Android TextInputLayout Adding Character Counting


Example

The TextInputLayout has a character counter for an EditText defined within it.
The counter will be rendered below the EditText.

Just use the setCounterEnabled() and setCounterMaxLength methods:

TextInputLayout til = (TextInputLayout) findViewById(R.id.username);
til.setCounterEnabled(true);
til.setCounterMaxLength(15);

or the app:counterEnabled and app:counterMaxLength attributes in the xml.

<android.support.design.widget.TextInputLayout
    app:counterEnabled="true"
    app:counterMaxLength="15">

    <EditText/>

</android.support.design.widget.TextInputLayout>
