If you want to enter only number then choose this android:digits="0123456789_".

ok.try the following code

   InputFilter[] Textfilters = new InputFilter[1];
    Textfilters[0] = new InputFilter(){
    public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
        // TODO Auto-generated method stub
        if (end > start) {

            char[] acceptedChars = new char[]{'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '_'};

            for (int index = start; index < end; index++) {
                if (!new String(acceptedChars).contains(String.valueOf(source.charAt(index)))) {
                return "";
                  }
                }
             }

Try and add this to your EditText

EditText text = findViewById(R.id.your_edit_text); /* Find your EditText here. */
text.setKeyListener(DigitsKeyListener.getInstance("0123456789_"));
