Resize the action bar icon

Question

I would like to have a big action bar. So I am resizing the action bar in the style, and now I am looking for resizing the icon and adding text.

Here is my style:

<!-- Application theme. --> <style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar"> <item name="android:textSize">22sp</item> <item name="android:actionBarSize">100dp</item> <item name="android:actionBarTabTextStyle">@style/MyActionBarTabText</item> <item name="android:actionButtonStyle">@style/MyActionButtonStyle</item> </style> <style name="MyActionButtonStyle" parent="android:style/Widget.ActionButton"> <item name="android:layout_width">fill_parent</item> </style> <style name="MyActionBarTabText" parent="android:style/Widget.Holo.ActionBar.TabText"> <item name="android:textColor">@color/white</item> <item name="android:textSize">25dp</item> </style> 

And my menu for actionBar (menu.xml):

 <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/app_setting" android:title="@string/app_setting" android:layout_width="match_parent" android:layout_height="match_parent" android:icon="@drawable/ic_setting" android:showAsAction="ifRoom" /> </menu> 

And In the main class:

 @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu, menu); return true; } 

In addition, I tried a few questions, but I could not get it to work.

I want to resize the action bar icon

How to resize the actionBar icon?
