    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"
