Eclipse ADT（android Pugin）拒绝在drawable文件夹中查找图像

Question

Off the bat, version information:

• Eclipse: Juno Release, build 20120614-1722
• Android: 4.4
• ADT: 20.0.0v201206242043-391819

There are many, many questions on SO regarding the various res/drawable folders (standard, drawable-hdpi , -mdpi , -ldpi , -xhdpi ) and on whether it's necessary to create the standard drawable folder if it doesn't exist, where Android/ADT/Eclipse will look for the @drawable/* files, etc. However, my question seems to not have been answered thus far.

It's a pretty striaghtforward problem. To put it simply, I placed a file name 'starbg.png' in my drawable-hdpi folder, then used the qualifier @drawable/starbg.png in a layout xml file. However, Eclipse is throwing an error:

error: Error: No resource found that matches the given name (at 'background' 
with value '@drawable/starbg.png').

Why? Unsure. I have tried the following solutions based on SO questions, all without success:

• Cleaning the project (multiple times)
• Creating a res/drawable folder (as one was not auto-generated by my version of ADT) and adding the image there
• Copying the file into every single related folder
• Renaming the file to star_bg.png
• Restarting Eclipse

The project is not complicated. It's an incredibly simple setup, with 2 views, one of which has nothing more than a LinearLayout with an android:background attribute (with layout and orientation info, of course), the other of which works like a charm.

So I'm stumped. Any help is hugely appreciated.

Answer 1

when you specify your resource, it should not include the file extension. that is, a resource file,

drawable/starbg.png

should be referenced as,

@drawable/starbg

eg,

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:background="@drawable/starbg"
  ...>
...
</RelativeLayout>
