bringToFront 在 GLsurface 视图的情况下不起作用

Question

在我的应用程序中，我将 openTok 用于音频和视频通话功能。附件是我为视频通话而创建的图像，用于旋转摄像头视图，其中有一个摄像头旋转图标。

在发布流之前，这个旋转相机的图标就在原位，但是一旦发布流，它就会消失。它正在发生，因为由于 z 顺序。发布流的代码如下：

    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 glsurface 得到 renderend，它就会出现在顶部并且旋转图标会返回。要恢复图标，我正在使用 bringtoFront() 但这不起作用。下面是布局的xml。

知道如何在 GLsurfaceview 上添加旋转图标吗？

Answer 1

一个选项是切换到使用 TextureView 而不是 GLSurfaceView，一般来说，使用 TextureView 而不是 GLSurfaceView 时，视图组合要容易得多。

您可以在构建 Session 时启用 TextureView

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