How To Change Included Toolbar Title And Drawable?

Issue

I have a hard time finding on how to change the Toolbar title and it's drawable in every and each Activity.

There is something on Android Documentation that states that to minimize APK size. It is recommended to re-used components.

I create a separate layout, and <include layout=""/> to each of my Activities like Help, About , and etc. I also put android:label="Title" on Manifest File.

Toolbar.xml

My Main:

How do I access this included Toolbar DRAWABLE and TITLE in my Activities ?

Update: I removed ActionBar .

Solution

You are using Toolbar. So no need to do anything with ActionBar. Just set your Toolbar as supportActionBar. Then set title and icon to your Toolbar.

Use the below code:

mToolbar = (Toolbar)findViewById(R.id.Toolbar);
setSupportActionBar(mToolbar);
setTitle("About");
getSupportActionBar.setIcon(R.id.ic_arrow_back_black_24dp);

And, Remove all your mActionBar codes. Hope this helps.
