Question

Even if I set the input type to numberdecimal or number, I have to cast the number to get the number. Then what is the use of input type in EditText views.

e.g.

int a = Integer.valueOf(editText.getText().toString());

One more thing, why do I need to use toString() with almost every views to get Text? In java, we could just getText anything from controls.

Answer 1

You have to parse Text to Integer because it doesn’t return int. It returns Editable formatted by input type. So if you set input type to numbers you get Editable which contains only numbers.
And you have to add toString() because EditText return Editables not Strings.
