    copied!<p>I'm making a simple Android game written in Java.</p> <p>I have my activity...</p> <pre><code>public class GameName extends Activity{ ... public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } </code></pre> <p>Inside the "main" layout I have a button that calls a method called "startTheGame":</p> <pre><code>public void startTheGame(View v) { theGame = new Panel(this); setContentView(theGame); } </code></pre> <p>Here is the panel code (simplified)</p> <pre><code>class Panel extends SurfaceView implements SurfaceHolder.Callback { public GameThread _thread; public Panel(Context context) { super(context); getHolder().addCallback(this); setFocusable(true); } ... @Override public void surfaceCreated(SurfaceHolder holder) { _thread = new GameThread(getHolder(), this); _thread.setRunning(true); _thread.start(); } ... } </code></pre> <p>So as you can see I have a "GameThread" class that is started... here it is below:</p> <pre><code>class GameThread extends Thread { private SurfaceHolder _surfaceHolder; private Panel _panel; private boolean _run = false; public GameThread(SurfaceHolder surfaceHolder, Panel panel) { _surfaceHolder = surfaceHolder; _panel = panel; } public void setRunning(boolean run) { _run = run; } @Override public void run() { Canvas c; while (_run) { c = null; try { ... if (health &lt;= 0) { _run = false; //change views? setContentView(R.layout.over); } c = _surfaceHolder.lockCanvas(null); synchronized (_surfaceHolder) { _panel.onDraw(c); } ... } finally { // do this in a finally so that if an exception is // thrown // during the above, we don't leave the Surface in an // inconsistent state if (c != null) { _surfaceHolder.unlockCanvasAndPost(c); } try { Thread.sleep(60); } catch (Exception e) { } } } } </code></pre> <p>Hopefully you can see that if the health is &lt;= 0 it stops the thread and I am trying to change to another layout I created called "over".</p> <p>It just stops the screen from updating (drawing) but I never see the new panel.</p> <p>I've tried:</p> <pre><code>GameName cs = ((GameName)getApplicationContext()) cs.setContentView(R.layout.over); </code></pre> <p>But I'm getting a ClassCastException...</p> <p>Please Help!</p>
