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 EditText edit     EditText  findViewById R id text xyz    edit getText tostring      When I try it doing inside the default oncreate   I get null values  So for best practice  do u recommend a separate class for referring these already defined gui elements in main xml  From here we can call various methods of these elements like gettext or settext

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

Well  it depends on your needs  Very often I keep my references to widgets in activity  as a class fields  - and set them in onCreate method  I think that is a good idea  Probably the reason for your nulls is that you are trying to call findViewById   before you set contentView   in your onCreate   method - please check that

The quickest solution to your problem I believe is that you simply are missing parentheses on your getText  Simply add    to edit getText   toString   and that should solve it
