DraggableView is an Android library to make floating draggable view easy, currently it only extends from ImageView. Now you can make any view (or viewgroup) draggable using extensions on Kotlin & provided utils class on Java

On root / project build.gradle file add maven { url 'https://jitpack.io' }

Example:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

On app build.gradle add implementation 'com.github.hyuwah:DraggableView:LatestVersion'

Example:

dependencies {
    ...
    implementation 'com.github.hyuwah:DraggableView:LatestVersion'
    ...
}

Note: check the number on Jitpack badge above for latest version

DraggableImageView

On Layout XML file

<io.github.hyuwah.draggableviewlib.DraggableImageView
            android:src="@mipmap/ic_launcher_round"
            android:id="@+id/draggableView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>

On Activity / Fragment file

var dv = findViewById<DraggableImageView>(R.id.draggableView)
dv.setOnClickListener {
    // TODO on click
}

You can extent any view or viewgroup to be draggable (i.e. Button, FrameLayout, Linearlayout, LottieView, etc)

Here's some example using TextView:

<TextView
            android:id="@+id/tv_test_draggable"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="DRAG ME!" />

var tv = findViewById<TextView>(R.id.tv_test_draggable)

tv.makeDraggable(Draggable.STICKY.AXIS_X, true) // default is STICKY.NONE & animated true

// First param is the axis:
// - Draggable.STICKY.AXIS_X
// - Draggable.STICKY.AXIS_Y
// - Draggable.STICKY.AXIS_XY
// - Draggable.STICKY.NONE

// Second param is animation toggle
// - true or false

If you're on java class, you could do it with the help of DraggableUtils

Here's some example using Button:

<Button
            android:id="@+id/tv_test_draggable"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="DRAGGABLE BUTTON!" />

Button button = findViewById(R.id.tv_test_draggable);

DraggableUtils.makeDraggable(button, Draggable.STICKY.AXIS_X, true); // default is STICKY.NONE & animated true

// First param is the view

// Second param is the axis:
// - Draggable.STICKY.AXIS_X
// - Draggable.STICKY.AXIS_Y
// - Draggable.STICKY.AXIS_XY
// - Draggable.STICKY.NONE

// Third param is animation toggle
// - true or false
