Combining layout_weight and maxHeight?

I have the following "button bar" layout setup:

<LinearLayout
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="vertical">
  <RelativeLayout
    android:id="@+id/button_bar"
    android:layout_width="fill_parent"
    android:layout_height="0dp"
    android:layout_weight="0.1"
    android:maxHeight="86px"
    android:orientation="horizontal">
    <Button
      android:id="@+id/home_button"
      android:layout_width="wrap_content"
      android:layout_height="fill_parent"
      android:layout_alignParentLeft="true"/>
    <Button
      android:id="@+id/level_button"
      android:layout_width="wrap_content"
      android:layout_height="fill_parent"
      android:layout_toRightOf="@+id/home_button"/>
    <Button
      android:id="@+id/help_button"
      android:layout_width="wrap_content"
      android:layout_height="fill_parent"
      android:layout_toRightOf="@+id/level_button"/>
    <Button
      android:id="@+id/sound_button"
      android:layout_width="wrap_content"
      android:layout_height="fill_parent"
      android:layout_alignParentRight="true"/>
  </RelativeLayout>
  <View
    android:layout_width="fill_parent"
    android:layout_height="0dp"
    android:layout_weight="0.9"/>
</LinearLayout>

I want the button bar (the RelativeLayout) height to be 10% of the screen height, so I used layout_weight="0.1" + layout_weight="0.9", but no more than 86 pixels, so I tried to use maxHeight="86px", but this doesn't work.

Do you have any clue how to achiveve 10% height combined with constant maximum height layout restriction, please?

It is fairly easy and probably the cleanest solution to subclass LinearLayout and create your own layout calculation.

Just override onLayout() and onMeasure().
