Android Media3 PlayerView 监听 SurfaceTextureListener

Android Media3 PlayerView 监听 SurfaceTextureListener

• 由于 PlayerView 内部已经设置过 SurfaceTextureListener 的监听了，不能直接设置

//androidx.media3.ui.PlayerView 设置 app:surface_type="texture_view"
View videoSurfaceView = playerView.getVideoSurfaceView();
if (videoSurfaceView == null) {
    return;
}
if (videoSurfaceView instanceof TextureView) {
  TextureView textureView = (TextureView) videoSurfaceView;
  //先 textureView.getSurfaceTextureListener() 得到系统已设置的监听
  textureView.setSurfaceTextureListener(new SurfaceTextureProxy(textureView.getSurfaceTextureListener(), new SurfaceTextureProxy.Listener() {
      @Override
      public void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height) {
          Log.e(TAG, "onSurfaceTextureAvailable: test");
      }
  }));
}

public class SurfaceTextureProxy implements TextureView.SurfaceTextureListener {

    //源对象
    private TextureView.SurfaceTextureListener originListener;
    private Listener listener;

    public SurfaceTextureProxy(TextureView.SurfaceTextureListener originListener, Listener listener) {
        this.originListener = originListener;
        this.listener = listener;
    }

    @Override
    public void onSurfaceTextureAvailable(@NonNull SurfaceTexture surface, int width, int height) {
        originListener.onSurfaceTextureAvailable(surface, width, height);
        Log.e("TAG", "onSurfaceTextureAvailable: zfq0221" + originListener);
        //
        listener.onSurfaceTextureAvailable(surface, width, height);
    }

    @Override
    public void onSurfaceTextureSizeChanged(@NonNull SurfaceTexture surface, int width, int height) {
        originListener.onSurfaceTextureSizeChanged(surface, width, height);
        //
        listener.onSurfaceTextureSizeChanged(surface, width, height);
    }

    @Override
    public boolean onSurfaceTextureDestroyed(@NonNull SurfaceTexture surface) {
        boolean result = originListener.onSurfaceTextureDestroyed(surface);
        //
        listener.onSurfaceTextureDestroyed(surface);
        return result;
    }

    @Override
    public void onSurfaceTextureUpdated(@NonNull SurfaceTexture surface) {
        originListener.onSurfaceTextureUpdated(surface);
        //
        listener.onSurfaceTextureUpdated(surface);
    }
