Make A Variable Final In Android Studio

When I try to make the variable A(String) equal to e(Which comes from a Plain Text) this appears in the line of the error(In the code below): Variable 'e' is accessed from within i

Solution 1:

You are trying to add a string to an EditText:

 A=""+e;

This can't be done.
You probably want to add a string to a string, instead:

 A = "" + e.getText().toString();

Solution 2:

You can't assign e to a, since e is an edittext while a is a String. This is a java problem, and I recommend you learning java from thenewboston's tutorials before getting into android. Anyway, you need to use

A = e.getText();

No need for final variables, which use the final keyword.

Using a final keyword here, would cause problems. A final variable can't be edited, and won't be a solution since the variable will hold a text representation of that EditText, not it's actual text. Just for the sake of completeness, though, a final variable is represented like this:

final String finalString = "This string will now for ever hold this value. This can't be changed.";
