You must update the View using the UI thread (not the SurfaceView thread). If you would like to make some View change from within the SurfaceView thread you must create a new RunOnUiThread which performs the View updating.

// From within SurfaceView thread
new Thread() {
    public void run() {
        activity.runOnUiThread(new Runnable() {     
            @Override
            public void run() {
                // Update view here
            }
        });
    }
}.start();
