findViewById not working for an include?

by

Try retrieving the <include /> and then searching within that

Make sure your root has the same ID as the root element in the included XML file.. ex

<include
    android:id="@+id/outer"
    layout="@layout/test" />

Then retrieve your “inner” content using:

FrameLayout outer = (FrameLayout)findViewById(R.id.outer);

ImageView iv = (ImageView)outer.findViewById(R.id.inner);
if (iv == null) {
    Log.e(TAG, "Not found!");
}
