Change Text for loading screen in ActionBar-PullToRefresh library

Question

I have successfully implemented ActionBar-PullToRefresh in my code. Now whenever I refresh the list it shows "Loading ..." text in ActionBar.

So how to change that text in ActionBar. Do I directly change the string in the library or is there any other way to do that...

Answer 1

Approved approach from the samples

Source: https://github.com/chrisbanes/ActionBar-PullToRefresh/tree/master/samples

1. Create a theme with text overrides (e.g. ptrPullText),
   that is, res/values/styles.xml:

   <resources>
       <style name="Theme.Holo.CustomPtrHeader" parent="android:Theme.Holo">
           <item name="ptrHeaderStyle">@style/Widget.Custom.PtrHeader</item>
       </style>
       <style name="Widget.Custom.PtrHeader" parent="android:Widget">
           <item name="ptrRefreshingText">Pulling down the internet</item>
       </style>
   </resources>
   

2. Apply the custom theme to your activity in AndroidManifest.xml

   <activity
       ...
       android:theme="@style/Theme.Holo.CustomPtrHeader" />
   

or Register you own HeaderTransformer

For the example on how to do this, please see the GridView sample.

or A little hackier way

Please note that setPullText is not on the HeaderTransformer interface, it's an instance method of DefaultHeaderTransformer:

attacher = PullToRefreshAttacher.get(this);
attacher.addRefreshableView(listView, this);
transformer = ((DefaultHeaderTransformer)attacher.getHeaderTransformer());
transformer.setRefreshingText("Pulling down the internet");
