Android Percentage Layout Height

There is an attribute called android:weightSum.

You can set android:weightSum=”2″ in the parent linear_layout and android:weight=”1″ in the inner linear_layout.

Remember to set the inner linear_layout to fill_parent so weight attribute can work as expected.

Btw, I don’t think its necesary to add a second view, altough I haven’t tried. 🙂

<LinearLayout
    android:layout_height="fill_parent"
    android:layout_width="fill_parent"
    android:weightSum="2">

    <LinearLayout
        android:layout_height="fill_parent"
        android:layout_width="fill_parent"
        android:layout_weight="1">
    </LinearLayout>

</LinearLayout>
