late reply, but wanted to say thanks, this fixed it. On to my next problem:
I'm trying to write my own View class to handle various events, using LunarLander as an example. Here's my simple layout and class: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <com.my.package.BoardView android:id="@+id/board" android:layout_width="fill_parent" android:layout_height="fill_parent"/> <TextView android:id="@+id/TopText" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="play area" /> <LinearLayout android:id="@+id/rowButtons" android:orientation="horizontal" android:layout_width="wrap_content" android:layout_height="wrap_content" > <Button android:id="@+id/btnPlay" android:text="Play" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <Button android:id="@+id/btnInfo" android:text="Info" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <Button android:id="@+id/btnSetup" android:text="Setup" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> <TextView android:id="@+id/InfoText" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="screen size:" /> </LinearLayout> public class BoardView extends SurfaceView { public BoardView(Context context, AttributeSet attrs) { super(context, attrs); } @Override protected void onSizeChanged(int w, int h, int oldw, int oldh) { // TODO Auto-generated method stub super.onSizeChanged(w, h, oldw, oldh); TextView info = (TextView) findViewById(R.id.InfoText); //info.setText("width : " + w + ", height : " + h); } } When I first ran it, it blew up with a NPE in onSizeChanged. So at least I knew it was getting there. I commented out the info.setText line and it ran fine, but the view is blank on the screen. Why are the various TextViews and buttons not visible? I couldn't find any guidelines in the docs as to how/where to place your View class in the layout.xml.
