        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"
     
            android:layout_toRightOf="@+id/top_left"
     
            android:background="#ffe40000"
     
            app:layout_heightPercent="20%"
     
            app:layout_widthPercent="30%" />
     
    
    
        <View
     
            android:id="@+id/bottom"
     
            android:layout_width="match_parent"
