Cast Button as String variable before getting/setting text

Question

How come this doesn't work:

 String btnText = ((Button)findViewById(R.id.my_Button).getText().toString();

But this does:

Button myButton = ((Button)findViewById(R.id.my_Button);
String btnText = myButton.getText().toString();

The getText() method can't resolve, but I'm not sure why when essentially these two line are the same.

You have to put one more closing small bracket after this : (R.id.my_Button) like - ((Button)findViewById(R.id.my_Button)) then you access Button getText() method. — Hareshkumar Chhelana

It cant find the method getText() because you are trying to call it from an Object type which was returned by the method findViewById

You forgot to add another layer of bracket to fully cast it as a Button to enable you to call the method getText()

String btnText = ((Button)findViewById(R.id.my_Button)).getText().toString();

For the second example you directly cast it and reference to an Button object therefore you can directly call getText method from the button object itself

After converting find view reference to Button then you can access getText() method of Button :

After adding closing small bracket :

String btnText = ((Button)findViewById(R.id.my_Button)).getText().toString();
