Activity和SurfaceView

当activity离开了前台，surfaceview会被销毁； 当activity回到前台，surfaceview又会被重新创建， 创建是发生在onResume()方法之后。

通过注册回调函数来监听surfaceview的各种状态

surfaceView.getHolder().addCallback(new SurfaceCallback());

 

private final class SurfaceCallback implements Callback{

public void surfaceViewChanged(SurfaceHolder holder,int format,int width){}

 

public void surfaceViewCreated(SurfaceHolder holder){}

 

public void surfaceDestroyed(SurfaceHolder holder){}

 

}
