how to set title in toolbar?

Question

Seems pretty simple question, but could't find any answer. How to change the toolbar title.

The toolbar is created by AppCompat Activity,not a custom created one. It has the app name as default.I would like to change its Name corresponding to the action the activity performs.

Note : I can change custom toolbar title using the below code,so please i am not looking for that.

Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
toolbar.setTitle("My Title");

Answer 1

You can set default Toolbar title as following:

YourActivity.this.setTitle("Your Title");

For fragment:

getActivity().setTitle("Your Title");

Answer 2

Set ActionBar title based on your need

ActionBar ab = getActionBar();
ab.setTitle("My Title");

Answer 3

getSupportActionBar().setTitle("Title")
