Remove Android Activity Title and Icon

My getting-to-know-and-to-love Android journey continues, and has now come to themes. This morning, I have been learning how to use themes to customize the action bar and remove its icon and title.

I first removed the icon and title by running this piece of code in my start activity’s onCreate method:

ActionBar actionBar = getActionBar();
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setDisplayShowTitleEnabled(false);

This works, but causes the icon and title to be removed with a small delay. You will see the icon and title while the activity loads, after which they fade away.

A better way to achieve this is to remove the icon and title with themes instead of with code. I removed the code above and did the following instead.

Create a default action bar style (optional)

You don’t have to do this, but I think that having a default action bar style is more consistent than just adding one for action bars without the icon and title.

In styles.xml, I added the following line to my app theme:

<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:actionBarStyle">@style/ActionBar</item>
    ...any additional theme styles here
</style>

I then added the ActionBar style, which looks like this:

<style name="ActionBar" parent="android:Widget.Holo.Light.ActionBar.Solid.Inverse">
    <item name="android:background">...any color or image here...</item>
</style>

Note that I use the theme convention created by Android Studio, which creates an AppBaseTheme as well as an AppTheme that inherits the base theme. This will make it easy to customize your action bar.

Create a second style without icon and title

With the base theme in place, let’s create an app theme without a title and icon. Below the AppTheme style tag, add this inheriting style:

<style name="AppThemeWithoutActionBarTitle" parent="AppTheme">
    <item name="android:actionBarStyle">@style/ActionBarWithoutTitle</item>
</style>

as well as a new action bar style:

<style name="ActionBarWithoutTitle" parent="@style/ActionBar">
    <item name="android:displayOptions">useLogo</item>
</style>

Apply the new action bar style

To apply the style, open your manifest file and add the following line to the activities that should use it:

android:theme="@style/AppThemeWithoutActionBarTitle"

After this, the affected activities should no longer display an title or icon.
