Dynamic Word Count for EditText

Question

I am trying to get the Dynamic Or Live word count for an Edit Text. To explain the problem, I have an EditText and a Textview inside a fragment, whenever the user enters a sentence in the EditText it should automatically count the number of words occurring in that sentence and display the number of words in the TextView.

I have implemented the Text Watcher but can't figure out the code snippet.

Any help will be appreciated.

One of the callbacks of a TextWatcher is afterTextChanged(Editable edit).

A Editable is what you get when you call getText on an EditText, which holds the current text, and therefore also knows the length of the current text.

So you can do something like this:

        editText.addTextChangedListener(new TextWatcher() {
            ...
            @Override
            public void afterTextChanged(Editable editable) {
                String currentText = editable.toString();
                int currentLength = currentText.length();
                textView.setText("Current length: " + currentLength);
            }
        });
