Question

I have an editText where a user inputs a phone number, but right when they click their first number, I want a \'+\' to appear in the beginning of the text. I have this code but

Answer 1

Use TextWatcher

editText.setImeOptions(EditorInfo.IME_ACTION_DONE);

Implement it like this. You can also trick it to fit your needs

editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_DONE) {
            // Specify your database function here.
            return true;
        }
        return false;
    }
});

Alternatively, you can use the OnEditorActionListener interface to avoid the anonymous inner class.
