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.

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);
}

but it will filter dot("."), comma(",") and other punctuation, not only emojis — HendraWD, May 29 '17 at 13:25

Well there is a trick, But I'm not sure that it could be helpful for your case. The trick is to set inputType as textEmailAddress

<EditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textEmailAddress" />

Also you can take a look at this answer .

KeyListener keyListener = new TextKeyListener(TextKeyListener.Capitalize.SENTENCES, false);
InputMethodManager imm = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
                setInput(YOUR_EDIT_TEXT, keyListener, imm);

Set up a TextWatcher on editText, in OnTextChanged, do the following,

String s = charSequence.toString();
Pattern p = Pattern.compile("[^A-Za-z0-9]");
Matcher m = p.matcher(s);
boolean b = m.find();
if(b == true){
 //give warning to user that special character is not allowed, 
//and delete or clear the last last character in charSequence .

}
