使ListView成为RefreshView的直接子级，也是第一个子级。它认为它已经到达了顶部，可能是因为在XML的顶部还有其他元素

xmlns:design="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:weightSum="1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:theme="@style/Theme.AppCompat"
tools:context="com.tag.instagramdemo.example.MainActivity"
android:background="@drawable/background1">

<ListView
    android:id="@+id/lvRelationShip"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >

</ListView>
