应用程序在android中运行时，屏幕解锁后出现黑屏

我想在锁定屏幕时保持屏幕方向和应用程序。

但是当我在应用程序运行时锁定屏幕后解锁屏幕时， 然后设备只显示黑屏。它通过触摸作出反应（通过日志检查）但没有显示任何内容。 我正在使用全屏大小的TextureView。

我使用三星Galaxy Note 4进行开发，其Android版本为4.4.4。

  1. 启动应用程序（由我开发）。
  2. 锁屏。
  3. 解锁屏幕。
  4. 显示黑屏。＆lt; ==我的问题

    5. 关于WindowManager的启动应用程序，屏幕锁定，屏幕解锁的日志正在跟随。

    Manifest.xml如下所示。

    
...
android:configChanges="keyboardHidden|orientation|screenSize"
android:screenOrientation="landscape"
...

    我很抱歉我的英语不好。我真的想解决这个问题。 有人帮助我！
