Use android:inputType="number" in your EditText xml

You can also add text watcher editText.addTextChangedListener (new MyTextWatcher ());

private class MyTextWatcher implements TextWatcher {

    @Override
    public void beforeTextChanged (CharSequence s, int start, int count, int after) {

    }

    @Override
    public void onTextChanged (CharSequence s, int start, int before, int count) {


    }

    @Override
    public void afterTextChanged (Editable s) {

    }
}
