PullToRefreshScrollView + 多条目

1. 首先是布局文件
<?xml version="1.0" encoding="utf-8"?>
<com.handmark.pulltorefresh.library.PullToRefreshScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/pull"
>
<comh.example.com.chenyixun.MyListView

android:layout_height="wrap_content"
android:id="@+id/list_view"
></comh.example.com.chenyixun.MyListView>
</com.handmark.pulltorefresh.library.PullToRefreshScrollView>下面是代码的操作package comh.example.com.chenyixun.MyFrangment;
