Alloy PullToRefresh

Description

The Titanium Alloy PullToRefresh widget allows to refresh the page with a pull down when using a ListView and TableView. Available for iOS and Android, without any dependencie.

• In the jsfile of your listView/tableView:

  • In the initialization of the file put this code:

      if (args.pulltorefresh) {
     		args.pulltorefresh.setCallback(api.doRefresh);
      }
    

  • In the function where you update your view you have to put this code:

      if (args.pulltorefresh && data) {
     		args.pulltorefresh.stop(data.length * 240, 20);
      }
    

    The first argument is the length of one item of your listView/tableView.

    The second argument [Optional] is the subtraction of the size of the header by the size of the navbar, if you don't have any navbar don't indicate this argument.

  • Add this function:

      doRefresh: function(e) {
      	// Call your update function
      },
    

Internationalization

This widget can be in multiples languages, that's there are 4 keys you have to indicate the string phrases :

1. loading
2. release_to_update
3. pull_to_reload
4. updated_at

You can for example put this code in your /i18n/en/string.xml file:

<string name="loading">Loading</string>
<string name="release_to_update">Release to update</string>
<string name="pull_to_reload">Pull to reload</string>
<string name="updated_at">Update at</string>

You can find the same example in french in the widget file i18n/fr/string.xml-dist.

Wishlist

Works also with ScrollView

The native ios RefreshControl don't work for ScrollView (see the doc).

Therefore maybe we can use instead of it the headerpullview used for Android. Surently in the next version if a kind dev can do it ?
