Just take 2 steps and problem would be more likely to get solved:

Step 1: Clean your project by clicking Project -> Clean.

Step 2: Rebuild your project by clicking Project -> Build All.

Also make sure that your layout xml files are syntax error free and you don't have any image which has non-acceptable names (such as a "-" between image name).

Check to see if you are importing the correct R file.

If there is an import for android.R... delete it and clean your project.
