I know it's too late, but in case someone still need help. Here is the working solution. Setting an error is pretty straight forward. But it will be displayed to user, when he request Focus on it. So to do the both thing on your own, User this code.

 firstName.setError("Enter FirstName");
 firstName.requestFocus();

Answer 3

u can use this :

@Override
        public void afterTextChanged(Editable s) {
            super.afterTextChanged(s);
            if (s.length() == Bank.PAN_MINIMUM_RECOGNIZABLE_LENGTH + 10) {
                Bank bank = BankUtil.findByPan(s.toString());
                if (null != bank && mNewPanEntered && !mNameDefined) {
                    mNewPanEntered = false;
                    suggestCardName(bank);
                }

---

private void suggestCardName(Bank bank) {
    mLastSuggestTime = System.currentTimeMillis();
    if (!bank.getName().trim().matches(getActivity().getString(R.string.bank_eghtesadnovin))) {
        inputCardNumber.setError(R.string.balance_not_enmb, true);

    }
}

Answer 4

You can show error as PopUp of EditText

if (editText.getText().toString().trim().equalsIgnoreCase("")) {
      editText.setError("This field can not be blank");
}

and that will be look a like as follows

firstName.addTextChangedListener(new TextWatcher()  {

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

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

    @Override
    public void afterTextChanged(Editable s)  {
        if (firstName.getText().toString().length <= 0) {
            firstName.setError("Enter FirstName");
        } else {
            firstName.setError(null);
        }
    }
 });

Answer 5

you could use an onchange event to trigger a validation and then you can display a toast if this is enough for you

Answer 6

private void showError() {
   mEditText.setError("Password and username didn't match");
}

Which will result in errors shown like this:

And if you want to remove it:

 textView.setError(null);
