Android Studio Java classes dont seemed linked to layout files

Question

I am having an issue where I can not link my layout files to my java classes. I am importing code that I know worked into another project, and I moved all the source code and its associated layout xml files to the other project. (copy and paste)

Is their a way to link them back>

Here is an example:

setContentView(R.layout.activity_camera_protocol_demo);

It can not resolve activity_camera_protocol_demo.

Is their a fix for this?

It also does this with text views and buttons ect that are on the layout file.

Try rebuilding or cleaning your project. You find these options under the Build option — Tasos, Aug 30 '15 at 22:54

Go to Build --> Rebuild Project. It solved to me all the problems I had.

@johnjil Try also cleaning your project. `Build --> Clean Project` – Francisco Romero Aug 30 '15 at 23:51
yeah I did that as well. Is there a file that would like these together? – john jil Aug 31 '15 at 00:07
@johnjil What is exactly the error that it gives to you? That it doesn't recognise the R file? – Francisco Romero Aug 31 '15 at 00:08
cant resolve symbol: StartTakePhotoButton (its a button.) – john jil Aug 31 '15 at 00:26
@johnjil Look at this link: http://stackoverflow.com/questions/21100688/android-studio-suddenly-cannot-resolve-symbols. Maybe it could solve your problem. – Francisco Romero Aug 31 '15 at 00:28
@johnjil And nothing changes? – Francisco Romero Aug 31 '15 at 01:05
no not at all. I think I might be missing a file somewhere – john jil Aug 31 '15 at 01:46
@johnjil Are you sure that the layout it's on the folder layouts? – Francisco Romero Aug 31 '15 at 10:12
yeah, I think this is pretty rare – john jil Sep 01 '15 at 01:52
@johnjil Yes, I never had seen this (with the solutions that I put above I could solve it). It is only with this layout or with all layouts that you have? – Francisco Romero Sep 01 '15 at 10:37
