I have been using ToolBar since it was added into Support v7 library. And I think I used it well. But there is a point I can\'t understand. Why
Yes, you should replace ActionBar with new toolbar.
Reasons
It looks modern and it follows new material design.
Unlike Action bar, toolbar is not part of window decor. You define it and place it just like any other widget... therefore, you have freedom to place it anywhere in the parent layout.
You have freedom to put any widget inside toolbar.
You can define multiple toolbars.
EDIT
What i meant is you can place other widgets (views) inside toolbar.
Create a separate layout file for the toolbar (good for reusability). In my case file name is main_toolbar.xml
Then include this toolbar in your main layout like this
As you can see in this example i placed TextView inside the toolbar
