compile 'com.github.ivbaranov:materialfavoritebutton:0.1.2'

Usage

Declare in XML (see xml attributes below for customization):

<com.github.ivbaranov.mfb.MaterialFavoriteButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

Or static initializer (see xml attributes below for customization):

MaterialFavoriteButton favorite = new MaterialFavoriteButton.Builder(this)
        .create();

Configure using xml attributes or setters in code:

app:mfb_animate_favorite="true"                  // to animate favoriting
app:mfb_animate_unfavorite="false"               // to animate unfavoriting
app:mfb_padding="12"             	 			 // image padding
app:mfb_favorite_image="@drawable/ic_fav"        // custom favorite resource
app:mfb_not_favorite_image="@drawable/ic_not_fav"// custom not favorite resource
app:mfb_rotation_duration="400"                  // rotation duration
app:mfb_rotation_angle="360"   			 	     // rotation angle
app:mfb_bounce_duration="300"             		 // bounce duration
app:mfb_color="black"              		 		 // black or white default resources (enum)
app:mfb_type="star"           			  		 // star or heart shapes (enum)

Make sure you are using either (mfb_favorite_image and mfb_not_favorite_image) or (mfb_color and mfb_type).

Set an OnFavoriteChangeListener to MaterialFavoriteButton:

favorite.setOnFavoriteChangeListener(
        new MaterialFavoriteButton.OnFavoriteChangeListener() {
          @Override
          public void onFavoriteChanged(MaterialFavoriteButton buttonView, boolean favorite) {
          	//
          }
        });

Set an OnFavoriteAnimationEndListener to MaterialFavoriteButton:

favorite.setOnFavoriteAnimationEndListener(
        new MaterialFavoriteButton.OnFavoriteAnimationEndListener() {
          @Override
          public void onAnimationEnd(MaterialFavoriteButton buttonView, boolean favorite) {
            //
          }
        });
Usage in RecyclerView

To avoid triggering animation while re-rendering item view make sure you set favorite button state in onBindViewHolder without animation:

favoriteButton.setFavorite(isFavorite(data.get(position)), false);
