<p>Got it. You have to override</p>

<pre><code>android:actionBarStyle
</code></pre>

<p>and then in your custom style you have to override</p>

<pre><code>android:titleTextStyle
</code></pre>

<p>Here's a sample. </p>

<p>In my themes.xml:</p>

<pre><code>&lt;style name="CustomActionBar" parent="android:style/Theme.Holo.Light"&gt;
        &lt;item name="android:actionBarStyle"&gt;@style/CustomActionBarStyle&lt;/item&gt;
&lt;/style&gt;
</code></pre>

<p>And in my styles.xml:</p>

<pre><code>&lt;style name="CustomActionBarStyle" parent="android:style/Widget.Holo.ActionBar"&gt;
        &lt;item name="android:titleTextStyle"&gt;@style/NoTitleText&lt;/item&gt;
        &lt;item name="android:subtitleTextStyle"&gt;@style/NoTitleText&lt;/item&gt;
&lt;/style&gt;

&lt;style name="NoTitleText"&gt;
        &lt;item name="android:textSize"&gt;0sp&lt;/item&gt;
        &lt;item name="android:textColor"&gt;#00000000&lt;/item&gt;
&lt;/style&gt;
</code></pre>

<p>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.</p>

<p>I'm very new to Android so correct me if I'm wrong, but I think if you decide to use navigation tabs on the Action Bar, they seemed to not be completely left aligned because the title text color is only transparent and hasn't gone away.</p>

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

我正在浏览Holo.Light主题，但我似乎找不到可以覆盖的神奇样式来摆脱在我的应用首次启动时短暂显示的标题文本。我该怎么做呢？
