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

Question

My application's main icon consists of two parts in one image: a logo and a few letters below it. This works well for the launcher icon for the app, but when the icon appears on the left edge of the ActionBar, the letters get cut off and it doesn't look good.

I would like to provide the ActionBar with a separate version of the icon, with only the "logo" part and not the letters beneath it, but so far have been coming up empty. I honestly can't find any answer to this, and I can't even find the question itself anywhere.

Answer 1

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).

Answer 2

In AndroidManifest.xml:

<application
    android:icon="@drawable/launcher"
    android:label="@string/app_name"
    android:name="com..."
    android:theme="@style/Theme">...</Application>

In styles.xml: (See android:icon)

<style name="Theme" parent="@android:style/Theme.Holo.Light">
    <item name="android:actionBarStyle">@style/ActionBar</item>
</style>
<style name="ActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
    <item name="android:icon">@drawable/icon</item>
</style>

Answer 3

Please try this line

getSupportActionBar().setHomeAsUpIndicator(R.drawable.back_arrow);

Answer 4

If you are using AppCompat, the only way to set the ActionBar icon on devices running Gingerbread (API 10) or below is by setting the android:icon attribute in every Activity in your manifest or setting the drawable programatically.

<manifest>
    <application>
        ...
        <activity android:name="com.your.ActivityName"
            ...
            android:icon="@drawable/ab_logo"/>
        ...
   </application>
</manifest>

Update: Be warned however that the application icon will be overridden if you set the android:icon attribute on the launch Activity. The only work around I know of is to have a splash or dummy Activity which then launches your main Activity.

Answer 5

Inspired by TheIT, I just got this to work by manipulating the manifest file but in a slightly different fashion. Set the icon in the application setting so that the majority of the activities get the icon. On the activity where you want to show the logo, add the android:logo attribute to the activity declaration. In the following example, only LogoActivity should have the logo, while the others will default to icon.

<application
    android:name="com.your.app"
    android:icon="@drawable/your_icon"
    android:label="@string/app_name">

    <activity
        android:name="com.your.app.LogoActivity"
        android:logo="@drawable/your_logo"
        android:label="Logo Activity" >

    <activity
        android:name="com.your.app.IconActivity1"
        android:label="Icon Activity 1" >

    <activity
        android:name="com.your.app.IconActivity2"
        android:label="Icon Activity 2" >

</application>

Hope this helps someone else out!

Answer 6

creating logo

in folders "drawable-..." create in all of them logo.png . The location of the folders: [YOUR APP]\app\src\main\res

In AndroidManifest.xml add line: android:logo="@drawable/logo"

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:logo="@drawable/logo"
    ...

that's it.

Answer 7

Please Try, if use "extends AppCompatActivity" and present actionbar.

 ActionBar eksinbar=getSupportActionBar();
if (eksinbar != null) {
    eksinbar.setDisplayHomeAsUpEnabled(true);
    eksinbar.setHomeAsUpIndicator(R.mipmap.imagexxx);
}

update

I think by default it uses your launcher icon... Your best bet is to create a separate image... Designed for the action bar and using that. For that check: http://developer.android.com/guide/topics/ui/actionbar.html#ActionItems
