Tostring problem in Android Studio

Question

I have String type variables and Int type variables. When I do getText.ToString() in a variable of type int Android Studio shows error due to variable type not being a String.

Would anyone know which option I can use for Int type variables?

Android Studio is complaining that the method insert() wait 3 parameters of type int, but you’re passing them as String, precisely by using the method toString(). Doesn’t make much sense.

In that case, you have to use the class wrapper Integer, more specifically the method parseInt(), that will take the contents of EditText and convert it to an integer value, returning a int:

Integer.parseInt(campo.getText().toString())
