I want to change the custom back button in sherloc

问题:

I dont like the default back button that comes with action bars they look rather to tiny for my liking. I trying to fix a bigger and more descriptive button like the one used in the WeChat Mobile App. please any body with an Idea.

I tried this below but did not work

<item name="android:homeAsUpIndicator">@drawable/back</item>  //Put in my style

The the one below in my code

 ActionBar actionBar = getSupportActionBar();
        actionBar.setHomeButtonEnabled(true);
        actionBar.setDisplayHomeAsUpEnabled(true);
      //  actionBar.setDisplayUseLogoEnabled(false);
        actionBar.setDisplayUseLogoEnabled(true);

But did not work. the image that I kept in my drawable is not show. My app icon keeps show on the action bar which I dont want. and the back button is not working. Please any idea.

try this :

<style name="YourTheme" parent="@style/Theme.Sherlock.Light.DarkActionBar">
    <item name="homeAsUpIndicator">@drawable/new_indicator</item>
    <item name="android:homeAsUpIndicator">@drawable/new_indicator</item>
</style>

And new_indicator xml file in drawable folder: new_indicator.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

<item
    android:left="0dp"
    android:right="5dp">
    <bitmap android:src="@drawable/indicator" /> <!-- this is your desired image -->
</item>

</layer-list>
