问题
Please let me know where I am going wrong to get the error.
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>
I have created a folder like
/res/layout-land
and add a layout called see_today_landscape_layout in it.
and in onCreate() I added the following
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.see_today_landscape_layout);
....
}
But when I run my app I am getting the following error

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...
I cleaned and rebuild the project for say 5 times, but still the issue occurs.
Strange point is that this was working yesterday and it\'s not working today. The code is the same.
回答1:
- in eclipse, go to Project > Clean...
- select your project, then press OK
- relaunch the app
if it happens again delete the r.java file. it will generate automatically.
回答2:
For my condition the cause was taking int parameter for TextView. Let me show an example
int i = 5;
myTextView.setText(i);
gets the error info above.
This can be fixed by converting int to String like this
myTextView.setText(String.valueOf(i));
As you write int, it expects a resource not the text that you are writing. So be careful on setting an int as a String in Android.
回答3:
Since you are setting the layout explicitly you might want to try and put it in the default /layout folder not in the /layout-land since that is if you want Android to automatically handle rotation for you.
回答4:
Try moving your layout xml from res/layout-land to res/layout folder
回答5:
This can happen due to a different language in the phone for which your code doesn't have the asset for. For example your preference.xml is placed in xml-en and you are trying to run your app in a phone which has French selected, the app will crash.
回答6:
In my case my Build Tools version in my build.gradle for the app module was outdated on an old project. Updating it fixed the issue:
android {
...
buildToolsVersion "19.0.1"
...
Updated to the latest build tools version (25.0.1) and sync'd the project and all was well again.
回答7:
Check to make sure that your imports are correct. I had a similar problem where R was pointing to the Android system R file, not my local one.
回答8:
I got this error from yet another reason:
I had the file res/xml/data.xml and I was trying to load it with Resources class like this:
Resources.getSystem().getXml(R.xml.data);
However this is incorrect as the method Resources.getSystem() returns a global shared Resources object that provides access to only system resources.
The correct way is as follows (from inside Activity):
this.getResources().getXml(R.xml.data);
回答9:
I deleted folders build inside a project. After cleaned and rebuilt it in Android Studio. Then corrected errors in build.gradle and AndroidManifest.
回答10:
This can also cause some trouble: Accidentally one of my layouts was parked in my tablet resources folder, so I got this error only with phone layout. The phone layout simply had no suitable layout file.
I worked again after moving the layout file in the correct standard folder and a following project rebuild.
回答11:
Make sure that the R you are pointing to is the correct one. I had a problem very similar to this, where an import got inserted by Eclipse that pointed to the System R file rather than the project one. It took a lot of head scratching. Hope this helps.
回答12:
You have screen orientation set to landscape in your xml. If you have used eclipse to generate this file it would have created under res/layout-land/ folder.But when you open activity in Portrait mode application will search for xml in res/layout-port/ folder or the regular res/layout/. If you didn't have xml for portrait mode your application will crash.
回答13:
I have fixed the by this way:
Create a folder in your resource directory name "drawable-nodpi" and then move yours all resources in this directory from others drawable directory.
Now clean your project and then rebuilt. Run again hopefully it will work this time without any resource not found exception.

I got this error when I was trying to access Bundle data from One Intent by using getInt("ID").
I solved it by using getString("ID").
From Activity1 i had
Intent intent=new Intent(this,ActivityB.class);
intent.putExtra("data",data)//
startActivity(intent);
On Activity B,
Bundle bundle=getIntent().getExtras();
if(extras!=null){
// int x=extras.getInt("Data"); This Line gave me error int
x=Integer.parseInt(extras.getString("Data")); // This solved the problem.
}
