Hi. I am new to Java; please excuse my ignorance.
I am trying to use ViewGroup in main.xml. However I am getting a
runtime exception because onLayout method isn't implemented. How do I
implement this method? The following is my partial code from
main.xml:
<ViewGroup android:id="@+id/controlPanel"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button android:id="@+id/alphaButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@+string/alpha" />
<Button android:id="@+id/rotateButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@+string/rotate" />
</ViewGroup>
and below in the application I try to implement onLayout method, but I
the autocompletion doesn't show 'onLayout':
controlPanel = (ViewGroup)findViewById(R.id.controlPanel);
//controlPanel ...here I get no autocompletion for onLayout
