The official Android Swiperefreshlayout

This is based on the latest V4 package implementation of a drop-down refreshed Dongdong ~ ~ ~

First of all, the whole is very simple, after all, is not a custom, but also please relax your heart!!! Not much nonsense to say, direct sticker code

Layout file:

<relativelayoutxmlns:Android="Http://schemas.android.com/apk/res/android"    xmlns:Tools="Http://schemas.android.com/tools"    Android: Layout_width="Match_parent"    Android: layout_height="Match_parent"    Tools: context=". Mainactivity "><android.support.v4.widget.swiperefreshlayout        Android: id="@+id/swipe_ly"        Android: Layout_width="Match_parent"        Android: layout_height="Match_parent"        ><listview            Android: id="@+id/lv"            Android: Layout_width="Match_parent"            Android: layout_height="Match_parent"></ListView></android.support.v4.widget.SwipeRefreshLayout></RelativeLayout>

The data is I a one to refresh out, the concrete implementation logic can be seen in the source code ~ ~ ~

As far as I know, if the V4 version of the effect is "know the client" that effect, now the latest this is currently used in the "Coursera" client, interested in the pot friends can see for themselves

(PS: Slag with Linux, for the moment have not found the more gratified gift recording tools, such as Bo friends have recommended, please leave a message to inform!!! Kneeling Thanks!!! ）
