Question

I have a complex layout situation in which an horizontal LinearLayout holds two other LinearLayouts. The content for those layouts is dynamic, can be any kind of views, and is generated at runtime from different independent sources.

I want to display both of them as long as there is enough space, and limit them to 50% of the available space each otherwise. So I want those child LinearLayouts to have layout_width="wrap_content" when there is enough space, and layout_weight="0.5" when there isn’t. This means that the space distribution could be 10-90, 25-75, 60-40; it would only be 50-50 when there isn’t enough space to show the entire content of both views. So far I haven’t find a way to do this from XML, so I’m doing it from code. My question is can I achieve what I want using only XML attributes? Will a different kind of layout be able to do it?

Here is my current layout XML:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:orientation="horizontal"
    android:padding="2dp" >

    <LinearLayout
        android:id="@+id/title_frame"
        android:layout_width="wrap_content"
        android:layout_height="48dp"/>

    <LinearLayout
        android:id="@+id/options_frame"
        android:layout_width="wrap_content"
        android:layout_height="48dp"/>

</LinearLayout>

It appears this cannot be achieved using only XML attributes.
