Download

compile 'com.github.ivbaranov:materialfavoritebutton:0.1.4'

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) app:mfb_size="48"

  // button size

Make sure:

you are using either ( mfb_favorite_image and mfb_not_favorite_image) or ( mfb_color and mfb_type).
if you change mfb_size attribute you should also provide your own combination of mfb_favorite_image and mfb_favorite_image resources and mfb_padding attribute that will fit your new dimensions, otherwise you can get blurred icon

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);
