How to detect if users stop typing in EditText android

Question

I have an EditText field in my layout. I want to perform an action when the user stops typing in that edittext field. I have implemented TextWatcher and use its functions

Answer 1

There is a very simple and easy way of doing this using RxBindings for Android,

Get the library if you haven't already,

compile 'com.jakewharton.rxbinding:rxbinding:0.4.0'

Add and modify this snippet to your needs,

RxTextView.textChanges(mEditText)
            .debounce(3, TimeUnit.SECONDS)
            .subscribe(textChanged -> {
                Log.d("TAG", "Stopped typing!");
            });

What is Debounce Operator? - Learn more about it here

In our context, debounce will only notify you of the text change inside the EditText after a certain time has passed from the last text change that occurred inside the EditText.

Here I am waiting for 3 seconds until the last text change happened to conclude that the user has stopped typing. You can modify it according to your needs.
