在我的应用程序中，我使用openTok作为音频和视频调用功能。附件是我正在创建的图像，用于视频调用，以旋转摄像机视图，有一个摄像机旋转图标。

在发布流之前，这个图标到旋转相机的位置是一样的，但是一旦流被发布，这个图标就消失了。它之所以发生，是因为z阶。如下所述的发布流的代码：

    private void startPublisherStreaming() {
    mPublisher = new Publisher.Builder(getContext())
            .resolution(Publisher.CameraCaptureResolution.LOW)
            .frameRate(Publisher.CameraCaptureFrameRate.FPS_7)
            .name(name)
            .build();
    mPublisher.setPublisherListener(VideoCallFragment.this);
    mPublisher.setStyle(BaseVideoRenderer.STYLE_VIDEO_SCALE, BaseVideoRenderer.STYLE_VIDEO_FILL);
    mPublisher.setPublishAudio(true);
    mPublisher.setPublishVideo(true);
    flSubStream.addView(mPublisher.getView());

    if (mPublisher.getView() instanceof GLSurfaceView) {
        ((GLSurfaceView) mPublisher.getView()).setZOrderOnTop(true);
    }

    ivFlipCamera.bringToFront();
    mSession.publish(mPublisher);
}

一旦眩光表面得到渲染，它就会出现在顶部，旋转图标就会返回。为了恢复图标，我使用的是bringtoFront()，但这不起作用。下面是用于布局的xml。

你知道如何在GLsurfaceview上引入旋转图标吗？

一种选择是切换到使用TextureView而不是GLSurfaceView，一般来说，当使用TextureView而不是GLSurfaceView时，视图合成要容易得多。

在构建会话时，可以通过这样做来启用TextureView。

Session builder = new Session.Builder(this, apiKey, sessionId)
    .sessionOptions(new Session.SessionOptions() {
        @Override
        public boolean useTextureViews() {
            return true;
        }
    }).build();
