Or maybe you can try android:maxLength="160" if that suits your needs

It's better to use TextWatcher :

Edt_txt_keyIn.addTextChangedListener(new TextWatcher() {
    private int position;

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

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

    @Override
    public void afterTextChanged(Editable s) {
        if (s.length() > 160) {
            Edt_txt_keyIn.setText(s.delete(position, position + 1));
        }
    }
});
