A more advanced way would be to use butterknife bindview  This eliminates redundant code   In your gradle under dependencies  add this 2 lines   compile  com jakewharton butterknife 8 5 1             exclude module   support-compat        apt  com jakewharton butterknife-compiler 8 5 1    Then sync up  Example binding edittext in MainActivity   import butterknife BindView     import butterknife ButterKnife    public class MainActivity     BindView R id name  EditTextView mName           public void onCreate Bundle savedInstanceState            ButterKnife bind this                           But this is an alternative once you feel more comfortable or starting to work with lots of data

Shortest  amp  Simplest getText editText   getText button   getText textView   Little Workaround Just make method in your BaseActivity   create BaseActivity if you don t have  public class BaseActivity extends AppCompatActivity      public String getText TextView tv            return tv getText   toString   trim              And extend your all activities by this BaseActivity  public class YourActivity extends BaseActivity      Override   public void onCreate Bundle savedInstanceState        getText editText        getText button        getText textView          Note that EditText  Button extends TextView  so I created only getText TextView tv

You might also want to take a look at Butter Knife  It aims at reducing the amount of boilerplate code by using annotation  Here is a simple example   public class ExampleActivity extends ActionBarActivity         InjectView R id name      EditText nameEditText        InjectView R id email      EditText emailEditText        Override     public void onCreate Bundle savedInstanceState            super onCreate savedInstanceState           setContentView R layout activity example           Butterknife inject this               OnClick R id submit      public void onSubmit              Editable name   nameEditText getText             Editable email   emailEditText getText              Just add the following dependency to your build gradle   compile  com jakewharton butterknife x y z    As an alternative there is also AndroidAnnotations

I guess you will have to use this code when calling the  mEdit  your EditText object    myActivity this mEdit getText   toString    Just make sure that the compiler know which EditText to call and use
