无法将CardView添加到Eclipse中的布局

Question

I am using Eclipse and trying to add CardView to my layout. However I keep getting an exception:

02-27 23:33:41.982: E/AndroidRuntime(20071): FATAL EXCEPTION: main
02-27 23:33:41.982: E/AndroidRuntime(20071): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.materialcontactpicker/com.example.materialcontactpicker.MainActivity}: android.view.InflateException: Binary XML file line #1: Error inflating class android.support.v7.widget.CardView

... most of the crap that you usually ignore ...

02-27 23:33:41.982: E/AndroidRuntime(20071):    ... 24 more  

I have:
1. Imported appcompat_v7 to my workspace, added it to libraries.
2. Imported cardview project and added it to libraries.
3. Configured the build path and added cardview to the "Projects".
4. My targetSdkVersion is 21.

However, I still get the error.

How do I solve this?

Answer 1

I faced the similar issue yesterday in eclipse. Below steps work for me.

1. Remove cardView project from buildpath. Delete existing CardView project from workspace.
2. Clean Project.
3. Restart eclipse.
4. Import CardView project again.
5. Right click on the CardView Project. Go to Properties. Make sure "is Library" option is checked.
6. Now right click on your project -> build path -> configure build path -> Under projects tab, add cardview.

Hope it helps..
