How to get text from EditText?

Question

The question is quite simple. But I want to know where exactly do we make our references to the gui elements? As in which is the best place to define:

final          


        

Answer 1

If you are doing it before the setContentView() method call, then the values will be null.

This will result in null:

super.onCreate(savedInstanceState);

Button btn = (Button)findViewById(R.id.btnAddContacts);
String text = (String) btn.getText();

setContentView(R.layout.main_contacts);

while this will work fine:

super.onCreate(savedInstanceState);
setContentView(R.layout.main_contacts);

Button btn = (Button)findViewById(R.id.btnAddContacts);
String text = (String) btn.getText();
