Android 当屏幕关闭时，应用程序停止工作

我已经创建了一个android应用程序，它在

横向

定向模式下工作。当屏幕处于活动状态时，它会使屏幕保持打开状态。但是，当我使用电源按钮锁定屏幕且应用程序打开时，它停止工作，并在

LogCat

中给出

Resources$NotFoundException

，指向活动的

onCreate（）

方法。请帮忙

注意：请记住，该应用程序在正常使用情况下工作正常。问题发生在我使用电源按钮关闭屏幕时。

从清单中删除“android:screenOrientation=“Sensor横向”，并发布活动菜单。xml

问题是我将布局xml文件保存在

布局栏

文件夹中，而不是

布局

文件夹中。当我锁定屏幕时，它在内部转为纵向模式（不知道为什么它总是保持该方向），并且由于它无法找到纵向模式的资源，它给出了

resources$NotFoundException

post logcat+您的清单file@MikeM. 试过了。没有区别：（@shayan It给出错误“您的tabhost必须有一个id为android.R.id.tabs的tabwidget”和“您的tabhost必须有一个id为android.R.id.tabcontent的framelayout”@MikeM.尝试了您的建议。没有区别。@MikeM。我的布局在layout land文件夹中，这就是它找不到它们的原因。谢谢您的时间：）我添加了

活动\u菜单

。如果我删除

sensorscape

，我如何将应用程序保持在

scape

方向？我的资源位于layout land文件夹中，这就是它找不到它们的原因。感谢您抽出时间：）
