我正在尝试在自定义textureview上播放一些rtsp视频。视频是第一次播放但是当我进入第二个活动时播放相同的视频（没有重新实例化，同一个会话但具有不同的纹理视图）那里正在播放并回到第一个活动，我在onResume textureview中再次设置sureface仍然显示它第一次离开的内容。有趣的事实就像视频仍在播放，只是它在纹理视图中不可见，如果我在显示之前转到第二个屏幕。我尝试释放surfacetexture而不释放，尝试释放我在第一个活动中持有引用以供将来使用的表面，而不是任何一个似乎都工作。可以是什么可能的原因？
在onResume我正在检查应用程序是否从应用程序抽屉或全屏活动回来。通过单击主页按钮使应用程序转到后台并从应用程序抽屉视频回到应用程序正在播放。只有当从完整回来时屏幕它不能正常工作。
