Can not find a View with findViewById()

Question

I cannot find a TextView by calling findViewById(), even though the ID does exist.

OtherActivity:

public class         


        

Answer 1

You have to call setContentView(...) BEFORE you attempt to find any of the UI components. You're trying to find the TextView before you've called it.

Change your code to this...

super.onCreate(savedInstanceState);
setContentView(R.layout.other_activity);
TextView textView = (TextView)findViewById(R.id.txt02);
