Android R参数指的是另一个未知的R.

Question

I have few .java files in my android project. I use R class several times in them.

However, in one file, I can't get it to work. When I use for example R.array.contextList (contexList array is in my generated R class) it says that contextList cannot be resolved or is not a field . When I press ctrl+space it suggests me arrays like emailAdressTypes or postalAddressTypes ... I have never seen those arrays. What's happening? Thanks

PS: I have cleaned my project several times and fixed errors in project several times.

Answer 1

See the imports.. if it has something like

android.R;

remove it and import your project's R.java

The documentation of android.R , this will explain where those things came from.
