How to count the number of characters in a string?

Question

Android

I need to display the number of characters entered in the EditText (Input) after pressing the button in the TextView (Output)

public void Count(View view) {
        String S = Input.getText().toString();
        Output.setText(S.length());
    }

For some reason it doesn't work, what am I doing wrong?

Answer 1

Debugger in hand and go ahead, look at what you have in the variable S, what is in Output, and whether Count is called at all.
