从曲面视图创建新视图

Question

我有一个小应用程序，我实现了一个表面视图。现在取决于某些条件（时间）我想将屏幕更改为不同的布局。如何在以下代码中执行此操作。

我正在做的事情的草图。

        public class df extends Activity 
      {

      public void onCreate(Bundle savedInstanceState) {


      }

class Panel extends SurfaceView implements SurfaceHolder.Callback {

    public Panel(Context context){
        super(context);
    }

    public void onDraw(Canvas canvas) {


    }

    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
        // TODO Auto-generated method stub
    }

    public void surfaceCreated(SurfaceHolder holder) {

    }

}

public void surfaceDestroyed(SurfaceHolder holder) {

    boolean retry = true;
    _thread.setRunning(false);
    while (retry) {
        try {
            _thread.join();
            retry = false;
        } catch (InterruptedException e) {
            // we will try it again and again...
        }
    }
}

}
