Bind TextView and variable?

Question

Android

Is it possible to somehow bind the value of some variable in the code to the TextView?
That is, so that when this variable changes, the text in the TextView will automatically change as well?
Or just manually use textView.setText() each time?

Answer 2

DataBinding has a very convenient two-way binding, just for such cases.
