Maskable Layout

The Maskable Layout is a simple framelayout that allows you to easily mask views and viewgroups. You can also execute other porterduffxfermodes. Simple Drawables are accepted, as wel as AnimationDrawables !

Usage

This example masks his child element (Imageview) with the mask "animation_mask" and sets the porterDuffXferMode to DST_IN

<com.christophesmet.android.views.maskableframelayout.MaskableFrameLayout
    android:id="@+id/frm_mask_animated"
    android:layout_width="100dp"
    app:porterduffxfermode="DST_IN"
    app:mask="@drawable/animation_mask"
    android:layout_height="100dp">

    <ImageView android:layout_width="match_parent"
               android:layout_height="match_parent"
               android:scaleType="centerCrop"
               android:src="@drawable/unicorn"/>
