Question

I’ve taken a program from a book as a template. In activity_main.xml I have:

android:id="@+id/contactID"//and 
android:id="@+id/contactName" 

both are specified in separate text views.

Then in mainActivity.java I have:

int[] views = new int[] {R.id.contactName, R.id.contactID};

Neither variable is defined in the java file which looks odd to me, but that’s what the book says…and eclipse says neither variable can be resolved or is a field so it won’t compile. It’s the correct contentView.

I’m guessing that R is supposed to pick these up when compiling – it doesn’t. I’ve tried cleaning with no joy. Sorry if I’m missing something really obvious.

Answer 1

Check your import. remove android.R if its imported. And import your R. Also make sure that you do NOT have any errors in your xmls, or else your R will not be generated.
