How do you remove the title text from the Android ActionBar?

Question

I\'m looking through the Holo.Light theme, and I can\'t seem to find the magic style to override to get rid of the title text that briefly shows up when my app

Answer 1

While all of these are acceptable, if your activity only contains a main activity, you can edit res\values\styles.xml like so:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

</resources>

I've updated parent and added the .NoActionBar property to the Light theme from Android Studios Create Blank Application Wizard.

You can change the style applied to each activity, or if you only want to change the behavior for a specific activity, you can try this:

setDisplayOptions(int options, int mask) --- Set selected display 
  or
setDisplayOptions(int options) --- Set display options.

To display title on actionbar, set display options in onCreate()

getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_TITLE, ActionBar.DISPLAY_SHOW_TITLE);

To hide title on actionbar.

getSupportActionBar().setDisplayOptions(0, ActionBar.DISPLAY_SHOW_TITLE);

The only thing that really worked for me was to add:

<activity 
    android:name=".ActivityHere"
    android:label=""

Answer 4

I think this is the right answer:

<style name="AppTheme" parent="Theme.Sherlock.Light.DarkActionBar">
    <item name="actionBarStyle">@style/Widget.Styled.ActionBar</item>
    <item name="android:actionBarStyle">@style/Widget.Styled.ActionBar</item>
</style>

<style name="Widget.Styled.ActionBar" parent="Widget.Sherlock.Light.ActionBar.Solid.Inverse">
    <item name="android:displayOptions">showHome|useLogo</item>
    <item name="displayOptions">showHome|useLogo</item>
</style>

Answer 5

In your Manifest

<activity android:name=".ActivityHere"
     android:label="">

Answer 6

Got it. You have to override

android:actionBarStyle

and then in your custom style you have to override

android:titleTextStyle

Here's a sample.

In my themes.xml:

<style name="CustomActionBar" parent="android:style/Theme.Holo.Light">
        <item name="android:actionBarStyle">@style/CustomActionBarStyle</item>
</style>

And in my styles.xml:

<style name="CustomActionBarStyle" parent="android:style/Widget.Holo.ActionBar">
        <item name="android:titleTextStyle">@style/NoTitleText</item>
        <item name="android:subtitleTextStyle">@style/NoTitleText</item>
</style>

<style name="NoTitleText">
        <item name="android:textSize">0sp</item>
        <item name="android:textColor">#00000000</item>
</style>

I'm not sure why setting the textSize to zero didn't do the trick (it shrunk the text, but didn't make it go away), but setting the textColor to transparent works.
