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。
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！
答案 0 :(得分：1)
然后解决方案很简单：
把它放在你的清单
中<android:screenOrientation="landscape">
