Say No More To TextWatcher Callback

As Android Developer, we have used TextWatcher callback to listen any of the changes in the EditText.

Something like this :

In Your xml Layout use OnTextChanged property

And call the view model user defined method to handle text changes in EditText. Full Snippet is below :

ViewModel User defined method can be like this (implement as per your implementation):

Now no more of TextWatcher callback in your View(Activity/Fragment), Instead use data binding to avoid boilerplate code.

Use MVVM, implement user defined method’s in View Model to handle OnTextChanged in xml.

Hope to see more of this implementation in future :-)

Cheers!!
