android - 应用程序在 android 中运行时屏幕解锁后黑屏

Question

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。它通过触摸使用react(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Samsung Galaxy Note 4开发，android版本是4.4.4。

1. 启动应用程序(由我开发)。
2. 锁定屏幕。
3. 解锁屏幕。
4. 出现黑屏。 <== 我的问题

有关启动应用程序、屏幕锁定、屏幕解锁的有关 WindowManager 的日志如下。

Manifest.xml 如下所示。

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

对不起我的英语不好。我真的很想解决这个问题。 谁帮帮我!

Answer 1

那么解决方法就很简单了:

把它放在你的 list 中

<android:screenOrientation="landscape">
