One simple trick we have to use is to make soft keyboard hidden at the app startup. As soon as the app starts the EditText gains the focus and the OS shows the keyboard covering the list items. If we don’t want this we can simply “move” the focus somewhere else:
1
2
	
android:focusable="true"
android:focusableInTouchMode="true"
