How to change title of Activity in Android?

Question

I am using

Window w = getWindow();
w.setTitle(\"My title\");

to change title of my current Activity but it does not seem to work.

Answer 1

I have a Toolbar in my Activity and a Base Activity that overrides all Titles. So I had to use setTitle in onResume() in the Activity like so:

@Override
  protected void onResume() {
    super.onResume();
    toolbar.setTitle(R.string.title);
  }
