Play

There is no need to explain what this thing does, just take a look at the gif below.

Including in your project

Add to your root build.gradle:

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

Add the dependency:

dependencies {
    compile 'com.github.alxrm:youtube-play-icon:0.9'
}

Usage

PlayIconDrawable

You can use it as a Drawable, and insert into any ImageView, with beautiful fluent API like this:

final ImageView iconView = (ImageView) findViewById(R.id.icon_play);
final PlayIconDrawable play = PlayIconDrawable.builder()
    .withColor(Color.WHITE)
    .withInterpolator(new FastOutSlowInInterpolator())
    .withDuration(300)
    .withInitialState(PlayIconDrawable.IconState.PAUSE)
    .withAnimatorListener(new AnimatorListenerAdapter() {
      @Override public void onAnimationEnd(Animator animation) {
        super.onAnimationEnd(animation);
        Log.d("Animation", "animationFinished");
      }
    })
    .withStateListener(new PlayIconDrawable.StateListener() {
      @Override public void onStateChanged(PlayIconDrawable.IconState state) {
        Log.d("IconState", "onStateChanged: " + state);
      }
    })
    .into(iconView);

All of these methods can be ignored, so the drawable will be created with it's default state

There is an PlayIconView, which extends ImageView and simply draws the icon and provides an API to work with it. You can use it in any layout.

API

To change icon state w/o animation, you can use:

PlayIcon.setIconState(@NonNull PlayIconDrawable.IconState state)

and to do the same with beautiful morphing animation:

PlayIcon.animateToState(@NonNull PlayIconDrawable.IconState state)

you also can use a convenient toggle method:

PlayIcon.toggle(boolean animated);

if you need to know whether the state is changed, there is a handy StateListener, you can set one with:

PlayIcon.setStateListener(@Nullable PlayIconDrawable.StateListener listener);
