Happy New Years 2020
Hi Everyone, Hello everyone. To read Or never read This is also the time of the entry of the blog. Has come to write again, has collected Libraries again, which would like to say that throughout the library has been collected for 2–3 years since the first article “Android Droidcon Developer Library GitHub update 14/02/60 Update Library Together on Valentine’s Day “The love story of Andrew.” At that time, it was said that the era in which Boom had a lot to write at that time. Because of the change from Java language to Kotlin because at that time the developers had to adapt in time With a world that must change Speaking when he first entered this industry, hehe
Come to know for a while It has changed to make the mobile industry accept that there are many changes. Because starting from the era of using android to write java, because from what I have observed, there is a beautiful Custom view to hope for User to download our App which admits that it is very difficult to use without having to config and must provide support versions of all Android versions. From the issue of Fragment, each version of android is a bug that doesn’t have an Android Jetpack. Anyone who wants to know that Android Jetpack can read this article. Can this
But now, in the kotlin collection functions, you can use without worrying.
[UPDATE] 100 Open-source Android apps written in Kotlin. Organized by Tech Stack and Architecture/Patterns.
Or can take what I have summarized Will be used examples and how to use Shortcut image style That subjects that use java straight

1.GoldMovies
The GoldMovies is based on Kotlin, MVVM architecture, coroutines, dagger, koin, and material designs & animations.
Module structure
The module structure is designed to try several different architectures.
Entity module : composed of entity models for persisting in database and response models for fetching data from network requests.
Network module :composed of abstractions for RESTful requests. And ApiResponseModel for standardizing a raw request model. An Interceptor for requesting every time with a query parameter api_key
Unit Tests to verify RESTful requests abstractions via a testing web server and mocked data.
Common-ui module composed of adapters and viewholders for composing recyclerview’s item via databinding. And some factories and extensions related to custom views.
Mvvm module is the implementation of user interfaces on the application. Based on mvvm architecture (view-databinding-viewmodel-model) with the repository pattern.
Attach TabLayout and RecyclerView. Useful for categorizing RecyclerView items.
What? 🤔
It is not a custom TabLayout or RecyclerView. It is just a helper library to attach to your RecyclerView with your TabLayout. If you don't want to go with sticky header RecyclerView or something like that, and also want to provide a good experience when your user is scrolling the content, this small library is for you.
How? 🤨
You fetch your product list and their categories. All you need to do is calcualate start index for all categories. Attacher will do the rest.
If your backend guy returns this json,
CategoryA -> 10 items (between 0..10)
CategoryB -> 20 items (between 10..30)
CategoryC -> 30 items (between 30..60)Then your offset list will be,
//3 tabs and their offset indexes in total list.
val categoryIndexOffsetList = [0,10,30]Then? 🙄
Then you attach.
TabScrollAttacher(tabLayout, recyclerView, categoryIndexOffsetList)
MDM is a library with the help of we can draw many different shapes like polygon, polyline and many more on the google map with editable mode.
Key Features:
- Draw any shape by touch on map
- Resize any shape by drag
- Remove any individual or all shapes from map
- Auto calculate the size of shapes drawn on map
- Customize shapes properties like color, stroke etc
- Easy callbacks for shapes draw, update and remove
Usage
// Simple Initialization
supportMapFragment.getMapAsync { googleMap ->
val mapDrawingManager = MDMBuilder(baseContext).withMap(googleMap).build()
mapDrawingManager?.removeListener = this //OnShapeRemoveListener
mapDrawingManager?.drawListener = this //OnShapeDrawListener
mapDrawingManager?.shapeType = ShapeType.POLYGON
}
Android app to showcase complex animations
Notes
- Read my article on Medium that breaks down these animations
- Download the APK or build code to view the app!
- UI was designed by Yaroslav Zubko. You can find it here.
- You can control the animation speed by opening the nav drawer and adjusting it.
Android Drop Down Tips List: A library for showing app tips on Android
A simple library for showing app tips on Android.
Tips can be set to be shown after a specific amount of time. They can also have an action button that will execute a provided Runnable and dismiss the tip when pressed.
Used in this app (also shown in “In-app example” gif below)
Kotlin
The title, description, action button text and action runnable can be set when creating an Item.
setAppearAfter() must also be called with:
- an initial time (Long) to start “counting down” from (e.g. app install time)
- a time in hours until the tip item is shown,
- a preference key which is used to store if an item has been dismissed (so it doesn’t show again)
How to Use :
val dropDownList: DropDownList = findViewById(R.id.drop_down_list)
dropDownList.preferences = preferencesval dropDownListItems = LinkedList<DropDownList.Item>()
var item: DropDownList.Itemitem = DropDownList.Item(
title = "Enter a title",
description = "Enter a description",
actionText = getString(android.R.string.ok),
action = Runnable {
// ...
}
)
item.setAppearAfter(appInstallTime, 0, "drop_list_example1")
dropDownListItems.add(item)item = DropDownList.Item(
title = "Example Item 2",
description = "Example Description 2",
actionText = "Action 2",
action = Runnable {
// ...
}
)
item.setAppearAfter(appInstallTime, 0, "drop_list_example2")
dropDownListItems.add(item)item = DropDownList.Item(
title = "Tip with no action",
description = "Tip description"
)
item.setAppearAfter(appInstallTime, 12, "drop_list_example2")
dropDownListItems.add(item)dropDownList.addAll(dropDownListItems)
Usage
Add ImagePickerView your Activity or Fragments Example.
ImagePickerView.Builder()
.setup {
config {
name { RESULT_NAME }
max { 5 }
}
}
.start(this) // if used fragment, .start(requireContext())Finish image select task, update ui for onActivityResult received data
For Example
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (resultCode == Activity.RESULT_OK) {
val images = data?.getParcelableArrayListExtra<Uri>(RESULT_NAME)
images?.let {
(recycler_view.adapter as ImageAdapter).submitList(it)
}
}
}This is a library to help developer faster on view an image full screen which has some gesture like double tap to zoom, span, zoom in/out, move.
Setup
- Add to build.gradle in app level
implementation 'com.github.tntkhang:full-screen-image-view-library:1.1.0'- Call open a FullScreenImageViewActivity and sent some appropriate data.
Intent fullImageIntent = new Intent(MainActivity.this, FullScreenImageViewActivity.class);
// uriString is an ArrayList<String> of URI of all images
fullImageIntent.putExtra(FullScreenImageViewActivity.URI_LIST_DATA, uriString);
// pos is the position of image will be showned when open
fullImageIntent.putExtra(FullScreenImageViewActivity.IMAGE_FULL_SCREEN_CURRENT_POS, pos);
startActivity(fullImageIntent);https://github.com/tntkhang/full-screen-image-view
A new way to improve navigation in your app
Its really easy integrate to your project
Usage
Really simple as I wrote earlier
Firstly, you should declare your view in xml file
<github.com.st235.lib_expandablebottombar.ExpandableBottomBar
android:id="@+id/expandable_bottom_bar"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_margin="20dp"
app:exb_backgroundCornerRadius="25dp"
app:exb_backgroundColor="#2e2e2e"
app:exb_itemInactiveBackgroundColor="#fff"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent" />Then you should add menu items to your navigation component
val bottomBar: ExpandableBottomBar = findViewById(R.id.expandable_bottom_bar)bottomBar.addItems(
ExpandableBottomBarMenuItem.Builder(context = this)
.addItem(R.id.icon_home, R.drawable.ic_bug, R.string.text, Color.GRAY)
.addItem(R.id.icon_go, R.drawable.ic_gift, R.string.text2, 0xFFFF77A9)
.addItem(R.id.icon_left, R.drawable.ic_one, R.string.text3, 0xFF58A5F0)
.addItem(R.id.icon_right, R.drawable.ic_two, R.string.text4, 0xFFBE9C91)
.build()
)bottomBar.onItemSelectedListener = { view, menuItem ->
/**
* handle menu item clicks here,
* but clicks on already selected item will not affect this callback
*/
}
bottomBar.onItemReselectedListener = { view, menuItem ->
/**
* handle here all the click in already selected items
*/
}
This is library to help you to add a sticky rotation label into your view.
xample Usage
<com.qifan.library.RotateLabelView
android:id="@+id/rotate_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@android:color/transparent"
app:background_color="@color/colorAccent"
app:label="Android"
app:layout_constraintEnd_toEndOf="@id/image"
app:layout_constraintTop_toTopOf="@id/image"
app:text_color="@android:color/white"
app:text_size="15sp" />
10.AppHead
Head View like Facebook Messenger for Android.
Components
AppHead has 3 main components
- HeadView: the draggable & dismissable view.
- DimissView: the view at the bottom that acts as bounds within which the HeadView can be dimissed.
- BadgeView(optinal): displays the number of notifications.
Usage
The most simple usage
AppHead.create(R.drawable.ic_messenger) {
headView { onClick {..} }
}.show(activity)Or using builders (proper for Java)
builder = Head.Builder(R.drawable.icon).headView(HeadView.Args().onClick {..})
AppHead(builder).show(activity)All available options
AppHead.create(R.drawable.ic_messenger_red) {
headView {
layoutRes(R.layout.app_head_red, R.id.headImageView)
onClick {..}
onLongClick {..}
alpha(0.9f)
allowBounce(false)
onFinishInflate {..}
setupImage {..}
onDismiss {..}
dismissOnClick(false)
preserveScreenLocation(false)
}
badgeView {
count("100")
position(BadgeView.Position.TOP_END)
}
dismissView {
alpha(0.5f)
scaleRatio(1.0)
drawableRes(R.drawable.ic_dismiss)
onFinishInflate {..}
setupImage {..}
}
}.show(this)Customize Components Layouts
In addition to configuring all options of the components, you also can define full custom components layouts. To customize HeadView, DimissView or BadgeView you must define the rootview as HeadView, DimissView or BadgeView

Change Language Programmatically in Android : http://gunhansancar.com/change-langua…
This is a helper library to change the language programmatically in Android.
Android by default uses the locale of the device to select the appropriate language dependent resources. And most of the time this behaviour is enough for common applications.
However, there are cases where you would want to change the language of your app and the UI of the app. As a result, LocaleHelper has emerged.
Features
- Changes language on-the-fly
- Persists the changes in
Preferencesautomatically - Detects changes when activity loads from backstack
- Detects Right-To-Left (RTL) languages and updates layout direction
- Small footprint (~3KB, ~50 methods), easy to use
13. BannerViewPager
Tencent Video,QQ Music,KuGou,AliPay,Tmall,TaoBao,YouKu,Himalaya,NetEase Music,Bilibili ect. All of above App’s Banner can be implements By BannerViewPager.
📱Introduction
MaterialDialog library is built upon Google’s Material Design library. This API will be useful to create rich, animated, beautiful dialogs in Android app easily. This library implements Airbnb’s Lottie library to render After Effects animation in app. Refer this for Lottie documentation.
Types of Dialog
MaterialDialog library provides two types of dialog i.e.
1. Material Dialog2. Bottom Sheet Material DialogThis is basic material dialog which has two material buttons (Same as Android’s AlertDialog) as you can see below.This is Bottom Sheet material dialog which has two material buttons which is showed from bottom of device as you can see below.
Bottom Sheet Material Dialog
BottomSheetMaterialDialog class is used to create Bottom Sheet Material Dialog. Its static Builder class is used to instantiate it. After building, to show the dialog, show() method of BottomSheetMaterialDialog is used.
BottomSheetMaterialDialog mBottomSheetDialog = new BottomSheetMaterialDialog.Builder(this)
.setTitle("Delete?")
.setMessage("Are you sure want to delete this file?")
.setCancelable(false)
.setPositiveButton("Delete", R.drawable.ic_delete, new BottomSheetMaterialDialog.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int which) {
Toast.makeText(getApplicationContext(), "Deleted!", Toast.LENGTH_SHORT).show();
dialogInterface.dismiss();
}
})
.setNegativeButton("Cancel", R.drawable.ic_close, new BottomSheetMaterialDialog.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int which) {
Toast.makeText(getApplicationContext(), "Cancelled!", Toast.LENGTH_SHORT).show();
dialogInterface.dismiss();
}
})
.build();// Show Dialog
mBottomSheetDialog.show();
HR Vertical calendar
The HR Vertical calendar for Android.
Demo
This awesome calendar is designed to meet more complex business requirements for Android development. And it’s easy to make a custom perfect ui. This calender is more flexible to adapt different ui and the complicated logic.
Vertical Calendar
The vertical calendar is build with ListView whose child item is CalendarCard with some information text. What you need to do is to setAdapter for the ListView.
Custom the UI
If you have a better design for the calender, you’ll find it’s easy to change to another style. It’s more convenient than System Calendar ui kit.

AndroidColorX (i.e: Android Color Extensions) is an Android library written in Kotlin that provides color utilities as Kotlin extension functions. The library relies on AndroidX ColorUtils for some of its calculations.
To convert a color type to any of the other types, you can use the extensions provided for it.
val color = Color.parseColor("#e91e63")val rgb = color.asRgb()
val argb = color.asArgb()
val hex = color.asHex()
val hsl = color.asHsl()
val hsla = color.asHsla()
val hsv = color.asHsv()
val cmyk = color.asCmyk()val colorHsl = HSLColor(hue = 210f, saturation = 0.5f, lightness = 0.5f)val colorInt = colorHsl.asColorInt()
val rgb = colorHsl.asRgb()
val argb = colorHsl.asArgb()
val hex = colorHsl.asHex()
val cmyk = colorHsl.asCmyk()
val hsla = colorHsl.asHsla()
val hsv = colorHsl.asHsv()
The same extensions are available for all the mentioned color types. Note that when converting from a color with an alpha component (i.e: ARGB or HSLA) to one without it (i.e: RGB or HSL) it will be a lossy conversion. If it's the other way around, conversions will assume full alpha (255 or 1f).
Also note that conversions from colors that store their components as Float (i.e: cmyk, hsl, hsla) to colors that store them as Int (i.e: RGBColor, ColorInt) and back will imply precision loss.
18.EasyReveal
EasyReveal is an extensible reveal library that contains various reveal animations. (Demo apk)
Getting started
Creating custom reveals
One of the core focuses of this library was extensibility. Creating your own reveal animation is as simple as extending ClipPathProvider and implementing the getPath() method. getPath() provides the Path for a given percent value on the provided view. The path gotten from getPath() is then used to clip the view using canvas.clipPath(path, op) (The op value is provided by the ClipPathProvider as well).
API Documentation
Documentation generated using Dokka : chrisvin.github.io/EasyReveal
The End?
No, infact, EasyReveal was a library that I created since I needed (but was unable to find) an extensible library for view clipping. Hence, the true form of EasyReveal is infact a view clipping library, who’s most obvious usecase is designing customizable reveal animations.
The first version of LiquidSwipe used EasyReveal as a dependency. If you like this library, you will probably love LiquidSwipe.
19.android-remote-temperature-control-client
Android Remote Temperature Control Client

20.Flourish
🎩 A polished and dynamic way to show up layouts.
Usage
Basic Example
Here is a basic example of implementing Flourish using Flourish.Builder class.
Flourish flourish = new Flourish.Builder(parentLayout)
// sets the flourish layout for showing and dismissing on the parent layout.
.setFlourishLayout(R.layout.layout_flourish_main)
// sets the flourishing animation for showing and dismissing.
.setFlourishAnimation(FlourishAnimation.BOUNCE)
// sets the orientation of the starting point.
.setFlourishOrientation(FlourishOrientation.TOP_LEFT)
// sets a flourishListener for listening changes.
.setFlourishListener(flourishListener)
// sets the flourish layout should be showed on start.
.setIsShowedOnStart(false)
// sets the duration of the flourishing.
.setDuration(800L)
.build();Create using kotlin dsl
This is how to create an instance of Flourish using kotlin dsl.
val myFlourish = createFlourish(parentLayout) {
setFlourishLayout(R.layout.layout_flourish_main)
setFlourishAnimation(FlourishAnimation.ACCELERATE)
setFlourishOrientation(FlourishOrientation.TOP_RIGHT)
setIsShowedOnStart(true)
setFlourishListener { }
}This library contain all utils related to google location. like, getting lat or long, Address and Location Setting dialog, many more…
What’s New in Ver 2.0

Edit text validation library using MVVM ( ViewModel + LiveData)
This is a simple library that facilitates text validation and error handling in a user-friendly way on EditText with (TextInputLayout support). For MVVM + data binding stack
open class ErrorCodeException(
open val errorCode: Int,
open vararg val args: Any?
) : ValidationException()open class StringException(val reason: String) : ValidationException()open class ResException(
@StringRes val resString: Int,
vararg val args: Any?
) : ValidationException()
25.jubako
A small API to help display rich content in a RecyclerView such as a wall of carousels
In this simple example we use some of Jubako’s convenience extensions to compose a RecyclerView with 100 rows.
Firstly the extension function RecyclerView.withJubako expresses which RecyclerView we want to load into (passing context) and then we follow up with a call to load describing what we want to load inside its lambda argument.
We can then make calls to Jubako’s withView extension function to specify each view (just a regular android.view.View) we wish to display for a row in our recycler that conveniently constructs the necessary boilerplate under the hood.
In the example we just print out 100 rows of static content, but Jubako was built to do much more than that.
Mostly this approach might work for simple applications, but under the hood Jubako offers more verbose construction to support more complicated scenarios.
The best place to start right now with Jubako is to check it the examples in the jubako-sample app in this repository.
Documentation is rough right now so the best place to begin would be to run & study the examples

🧀 Reacts dynamically with an indicator when the scroll is changed.
IndicatorScrollView
IndicatorScrollView is a scrollView for reacting with IndicatorView when scroll is changed.
It extends NestedScrollView. So it must have a ViewGroup child like what LinearLayout or RelativeLayout.
IndicatorView
IndicatorView is an indicator view for reacting to IndicatorScrollView when the scroll is changed.
It should be used in IndicatorScrollView.
Create using builder class
We can create an instance of the IndicatorView using IndicatorView.Builder class.
val indicatorView = IndicatorView.Builder(this)
.setIndicatorItemPadding(16)
.setExpandingRatio(0.2f)
.setExpandingAllItemRatio(1.0f)

.setFoldedWidth(200)
.setFoldedHeight(100)
.setCornerRadius(6)
.setLiftHorizontalDuration(400)
.setLiftVerticalDuration(200)
.setOnExpandListener { toast("expanded: $it") }
.build()Expand and Collapse
We can expand and collapse using the below methods.
doubleLiftLayout.expand() // expand the width and height size sequentially.
doubleLiftLayout.collapse() // collapse the width and height size sequentially.or we can do something after expanded using lambda.
doubleLiftLayout.expand { toast("expanded") }
doubleLiftLayout.collapse { toast("collapsed") }This library is inspired by the instagram video button having the same animation, look and feel.
Kotlin

33:BottomDrawer
BottomSheet with animations https://medium.com/@heyalex/bottom-sh…
You can make your own HandleView and implement TranslationUpdater interface for getting callbacks. Or you can use defined handle views by library like PlainHandleView or PullHandleView (check sample app).
After customizing theme and choosing handle view, you need to override configureBottomDrawer method and pass theme, handle view to BottomDrawerFragment.
So the following example will make Google Tasks fragment like on main preview:
class GoogleTaskExampleDialog : BottomDrawerFragment() {override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
super.onCreateView(inflater, container, savedInstanceState)
return inflater.inflate(R.layout.your_layout, container, false)
}override fun configureBottomDrawer(): BottomDrawerDialog {
return BottomDrawerDialog.build(context!!) {
theme = R.style.Plain
//configure handle view
handleView = PlainHandleView(context).apply {
val widthHandle =
resources.getDimensionPixelSize(R.dimen.bottom_sheet_handle_width)
val heightHandle =
resources.getDimensionPixelSize(R.dimen.bottom_sheet_handle_height)
val params =
FrameLayout.LayoutParams(widthHandle, heightHandle, Gravity.CENTER_HORIZONTAL)params.topMargin =
resources.getDimensionPixelSize(R.dimen.bottom_sheet_handle_top_margin)layoutParams = params
}
}
}
}
📱 Android library to open JSON from assets

// error
}
});
Get JSON as JSON Object:
JSONLoader.with(getApplicationContext())
.fileName("filename.json")
.getAsJSONObject(new JSONObjectLoaderListener() {
@Override
public void onResponse(JSONObject response) {
// response as JSONObject
}@Override
public void onFailure(Exception error) {
// error
}
});
Get JSON as JSON Array:
