I have textView1 under Relative Layout in graphical layout view. But when I follow the code for MainActivity.java, I can't find textView1 under id.

Simply go back to you layout .xml file with the graphical editor. Select the text view you mentioned and look for its id in the properties panel just below it.
Text View 1

Text View 2

Just make sure you are calling it from the R resource file like this in MainActivity.java file 

TextView mTextLabel = (TextView) findViewById(R.id.textView1);

You could also check if you might have added a different id to the textView.
Ask again if this does not help.
