Android: must override a superclass Method

Android often has this problem during the eclipse import project. Many statements about the @ override mark error are as follows:

"Eclipse uses Java 1.5 for compilation by default when no settings are made.Code, So this problem often occurs.

Solution:

Select window-> preferences-> JAVA-> Compiler (eclipse on Mac-> preferences-> JAVA-> compiler), and check that the compiler of version 1.6 is selected"

But I opened it and saw that it was actually 1.7, which should be more advanced than 1.6, and there is still an error, depressed, and only the @ override mark can be removed, regardless of him ~
