How to create a Video play button to stay invisible for a recor android application?

[imso]

Is there any way to get the play button to stay hidden in the background during recording until the user intervene to click the screen to allow the button to resurface the play button to stop the recording process?? Is the code coded in the .xml file or somewhere else.. How it be done??

After reading the link you provided i'm still quite lost on how should i integrate the surfaceview to the buttons similar to youtube to stop and start recording.. Sorry i'm very kinna bad in programming..

public class CameraTest extends Activity implements SurfaceHolder.Callback {
	
	private static final String TAG ="CAMERA_TUTORIAL";
	
	private SurfaceView surfaceView;
	private SurfaceHolder surfaceHolder;
	private Camera camera;
	private boolean previewRunning;

	File tempFile = null;
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        surfaceView = (SurfaceView)findViewById(R.id.surface_camera);
        surfaceHolder = surfaceView.getHolder();
        surfaceHolder.addCallback(this);
        
        surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
        
        Button btnStart = (Button) findViewById(R.id.button4);
        btnStart.setOnClickListener(new View.OnClickListener() 
        {
        	public void onClick(View v)
        	{
        		startRecording();
        	}
        	
        });
        
        Button btnStop = (Button) findViewById(R.id.button5);
        btnStop.setOnClickListener(new View.OnClickListener() 
        {
        	public void onClick(View v)
        	{
        		stopRecording();
        	}
        	
        });
    }
    @Override
    public void surfaceCreated(SurfaceHolder holder) {
    	camera = Camera.open();
    	if (camera != null) {
    		Camera.Parameters params = camera.getParameters();
    		camera.setParameters(params);
    	}
    	else {
    		Toast.makeText(getApplicationContext(), "Camera not available!", Toast.LENGTH_LONG).show();
    		finish();
    	}
    }
