Android: How to Change the Actionbar "Home" Icon to Be Something Other Than the App Icon

Android: How to change the ActionBar Home Icon to be something other than the app icon?

The ActionBar will use the android:logo attribute of your manifest, if one is provided. That lets you use separate drawable resources for the icon (Launcher) and the logo (ActionBar, among other things).

Show both app icon and back arrow in ActionBar in Android App

Try this.

I tested and It works.

    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDisplayShowHomeEnabled(true);
    getSupportActionBar().setLogo(getResources().getDrawable(R.drawable.ic_launcher));
    getSupportActionBar().setDisplayUseLogoEnabled(true);

EDIT

    getSupportActionBar().setTitle("Your Actionbar Title");

How to change option menu icon in the action bar?

The following lines should be updated in app -> main -> res -> values -> Styles.xml

 <!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    <item name="android:actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>
</style>

<!-- Style to replace actionbar overflow icon. set item 'android:actionOverflowButtonStyle' in AppTheme -->
<style name="MyActionButtonOverflow" parent="android:style/Widget.Holo.Light.ActionButton.Overflow">
    <item name="android:src">@drawable/ic_launcher</item>
    <item name="android:background">?android:attr/actionBarItemBackground</item>
    <item name="android:contentDescription">"Lala"</item>
</style>

This is how it can be done. If you want to change the overflow icon in action bar

Changing the Action bar icon

getActionBar();

You're throwing the action bar away right there. getActionBar() returns an instance of ActionBar, which you then need to call setIcon() on. Like so:

ActionBar actionBar = getActionBar();
actionBar.setIcon(R.drawable.my_icon);
