Code implementation Android5.0 drop-down refresh effect

To implement a drop-down refresh similar to Gmail.

One, defined in the XML file

This control is provided in SupportV4, called Swiperefreshlayout. This view is actually a parent control that we can define as follows.

<Android.support.v4.widget.SwipeRefreshLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Android:id= "@+id/swipe_container"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent" >    <ListViewAndroid:id= "@+id/listview"Android:layout_width= "Match_parent"Android:layout_height= "Wrap_content"android:padding= "16DP" /></Android.support.v4.widget.SwipeRefreshLayout>

There is no feeling it and the ListView a dime relationship is not! It's so convenient, it's much simpler than the previous ListView drop-down refresh. As soon as the user pulls down in the range of the control, a pull-down round ball will appear automatically. In practical use, we still need to do simple processing in Java code.

Second, through the Java code to set up

 mswipelayout = (Swiperefreshlayout) Findviewbyid (R.id.swipe_container); Mswipelayout.setonrefreshlistener ( this         );  //  set the color on the drop-down circle, blue, green, orange, red   Mswipelayout.setcolorschemeresources (Android. R.color.holo_blue_bright, Android. R.color.holo_green_light, Android. R.color.holo_orange_light, Android.        R.color.holo_red_light); Mswipelayout.setdistancetotriggersync ( 400); //  setting how much distance the finger pulls down on the screen triggers a drop-down refresh  mswipelayout.setprogressbackgroundcolor (r.color.red); //  Set the background of the drop-down circle  mswipelayout.setsize (swiperefreshlayout.large); //Set the size of the circle  

When you set the background and the size of the circle, it looks like this:

To set up listeners:

 Public class extends Implements Swiperefreshlayout.onrefreshlistener {//... }

/** method in listener Swiperefreshlayout.onrefreshlistener, trigger after pull refresh*/     Public voidOnrefresh () {NewHandler (). postdelayed (NewRunnable () {@Override Public voidrun () {//Stop RefreshMswipelayout.setrefreshing (false); }        }, 5000);//send message after 5 seconds, stop refresh}
