Question

How can I create a layout that has an always present EditText that obeys the following three rules:

The EditText view:

1. fills the entire parent if no image is present (at runtime, the visibility will be set to View.GONE in this case.)
2. fills 50% of the parent height if the image is taller than it is wide.
3. fills the remainder of the parent if the image is wider than it is tall.

The image, of course, is stretched to fit inside the bottommost 50% of the parent rectangle while preserving aspect ratio.

Here’s how I did it. The resulting layouts look like this:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <EditText
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:text="blah" />

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:visibility="gone"
        android:src="@drawable/photo1" />

</LinearLayout>
