copied!<p>This is how I was able to set the padding between the home icon and the title.</p> <pre><code>ImageView view = (ImageView)findViewById(android.R.id.home); view.setPadding(left, top, right, bottom); </code></pre> <p>I couldn't find a way to customize this via the ActionBar xml styles though. That is, the following XML doesn't work:</p> <pre><code><style name="ActionBar" parent="android:style/Widget.Holo.Light.ActionBar"> <item name="android:titleTextStyle">@style/ActionBarTitle</item> <item name="android:icon">@drawable/ic_action_home</item> </style> <style name="ActionBarTitle" parent="android:style/TextAppearance.Holo.Widget.ActionBar.Title"> <item name="android:textSize">18sp</item> <item name="android:paddingLeft">12dp</item>  </style> </code></pre> <p>However, if you are looking to achieve this through xml, these two links might help you find a solution:</p> <p><a href="https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/styles.xml" rel="noreferrer">https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/styles.xml</a></p> <p>(This is the actual layout used to display the home icon in an action bar) <a href="https://github.com/android/platform_frameworks_base/blob/master/core/res/res/layout/action_bar_home.xml" rel="noreferrer">https://github.com/android/platform_frameworks_base/blob/master/core/res/res/layout/action_bar_home.xml</a> </p>
