How can I restrict EditText to take emojis

Question

I am developing an application where I want my edittext should take Name only. I have tried using android:inputType="textCapSentences" but it seems like its not working. My edittext is still taking the emojis.

So, Is there any way i can restrict any special character or emojis input in edit text in android. If anyone have idea,Please reply. Thanks in advance.

Answer 1

you can use emoji filter as code below

mEditText.setFilters(new InputFilter[]{EMOJI_FILTER});

public static InputFilter EMOJI_FILTER = new InputFilter() {
    @Override
    public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
        boolean keepOriginal = true;
        StringBuilder sb = new StringBuilder(end - start);
        for (int index = start; index < end; index++) {
            int type = Character.getType(source.charAt(index));
            if (type == Character.SURROGATE || type == Character.OTHER_SYMBOL) {
                return "";
            }
            char c = source.charAt(index);
            if (isCharAllowed(c)) 
                sb.append(c);
            else
                keepOriginal = false;
        }
        if (keepOriginal)
            return null;
        else {
            if (source instanceof Spanned) {
                SpannableString sp = new SpannableString(sb);
                TextUtils.copySpansFrom((Spanned) source, start, sb.length(), null, sp, 0);
                return sp;
            } else {
                return sb;
            }
        }
    }
};

private static boolean isCharAllowed(char c) {
    return Character.isLetterOrDigit(c) || Character.isSpaceChar(c);
}
