Okay, sorry for asking this question. I have no idea how to solve this problem. I am creating a new project in eclipse, put some XML files in res/layout folder, and then drag an drop existing java files to src folder. I tried to generate R.java by cleaning the project and then these error messages appear:
[2014-02-10 18:28:01 - EventPlanner] W/ResourceType( 7228): ResXMLTree_node size 0xffffffff or headerSize 0xffff is not on an integer boundary.
[2014-02-10 18:28:01 - EventPlanner] E:\Andika\workspaces\EventPlanner\res\layout\activities_list.xml:6: error: Error: No resource found that matches the given name (at 'id' with value '@id/activity_id').
[2014-02-10 18:28:01 - EventPlanner] E:\Andika\workspaces\EventPlanner\res\layout\activities_list.xml:7: error: Error: No resource found that matches the given name (at 'id' with value '@id/chk_box').
[2014-02-10 18:28:01 - EventPlanner] E:\Andika\workspaces\EventPlanner\res\layout\activities_list.xml:10: error: Error: No resource found that matches the given name (at 'id' with value '@id/res_text').
.....
And R.java file wasn't generated. I have tried to close the eclipse and then re open again but it doesn't solve my problem. Did I miss something? Thank you
Edit: this is one of my XML layout

Where ever you getting the error in xml file.
1) Just delete that whole id and rename it again with new id name.
2) I can see you are also getting errors while setting styles and background resources. just delete and define it again in your xml file and clean your project.
I hope this resolves your problem.....
