    xmlns:app="http://schemas.android.com/apk/res-auto"
 
    android:layout_width="match_parent"
 
    android:layout_height="match_parent">
 

    <View
 
        android:id="@+id/top_left"
 
        android:layout_width="0dp"
 
        android:layout_height="0dp"
 
        android:layout_alignParentTop="true"
 
        android:background="#ff44aacc"
 
        app:layout_heightPercent="20%"
 
        app:layout_widthPercent="70%" />
 

    <View
 
        android:id="@+id/top_right"
 
        android:layout_width="0dp"
 
        android:layout_height="0dp"
 
        android:layout_alignParentTop="true"

    <View
 
        android:id="@+id/bottom"
 
        android:layout_width="match_parent"
