How do I change the android actionbar title and icon

This is very simple to accomplish

If you want to change it in code, call:

setTitle("My new title");getActionBar().setIcon(R.drawable.my_icon);

And set the values to whatever you please.

Or, in the Android manifest XML file:

<activity android:name=".MyActivity"        android:icon="@drawable/my_icon"        android:label="My new title" />  

To enable the back button in your app use:

 getActionBar().setHomeButtonEnabled(true); getActionBar().setDisplayHomeAsUpEnabled(true);

The code should all be placed in your onCreate so that the label/icon changing is transparent to the user, but in reality it can be called anywhere during the activity's lifecycle.

To make a single icon be usable by all your action bars you can do this in your Android Manifest.

<application    android:logo="@drawable/Image">    ...</application>

You just need to add these 3 lines of code. Replace the icon with your own icon. If you want to generate icons use this

getSupportActionBar().setHomeAsUpIndicator(R.drawable.icon_back_arrow);getActionBar().setHomeButtonEnabled(true);getActionBar().setDisplayHomeAsUpEnabled(true);
