获取 android.content.res.Resources$NotFoundException: 即使资源存在于 android 中也会出现异常 [英] Getting android.content.res.Resources$NotFoundException: exception even when the resource is present in android

问题描述

请让我知道哪里出错了.

Please let me know where I am going wrong to get the error.

我正在创建一个应用程序，它的一项活动只​​能处于横向模式.所以我在 AndroidManifest.xml 文件中添加了以下内容

I am creating an app which have one of its activity to be only in landscape mode. So I added the following in AndroidManifest.xml file

<activity android:name=".LandScapeImageActivity" android:screenOrientation="landscape"></activity>

我创建了一个像

/res/layout-land

/res/layout-land

并在其中添加一个名为 see_today_landscape_layout 的布局.

and add a layout called see_today_landscape_layout in it.

并在 onCreate() 中添加了以下内容

and in onCreate() I added the following

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.see_today_landscape_layout);
....
}

但是当我运行我的应用程序时，我收到以下错误

But when I run my app I am getting the following error

我在 R.java 中交叉检查，它具有 ID 为 7f03002b 的资源，异常正在寻找该资源并且它存在于那里...

I crossed checked in R.java and it has the resource with the ID 7f03002b which the exception is looking for and it is present in there...

我清理并重建项目 5 次，但问题仍然存在.

I cleaned and rebuild the project for say 5 times, but still the issue occurs.

奇怪的一点是，这昨天有效，今天无效.代码是一样的.

Strange point is that this was working yesterday and it's not working today. The code is the same.

推荐答案

1. 在 Eclipse 中，转到 Project > Clean...
2. 选择您的项目，然后按 OK
3. 重新启动应用

如果再次发生，请删除 r.java 文件.它会自动生成.

if it happens again delete the r.java file. it will generate automatically.
