I guess imp1 and imp2 are EditTexts,
so imp1.text and imp2.text are of type Editable and not String.
If result is a TextView you must do this:
result.text = (imp1.text.toString().toInt() + imp2.text.toString().toInt()).toString()
or if result is an EditText:
result.setText((imp1.text.toString().toInt() + imp2.text.toString().toInt()).toString())

You can still use old java method
(Integer.parseInt(imp1.text.toString()) + Integer.parseInt(imp2.text.toString()))
