RefreshableView
可下拉刷新的ViewGroup、ListView
RefreshableView:
main_xml:
<com.wangjie.refreshableview.RefreshableView
xmlns:rv="http://schemas.android.com/apk/res/com.wangjie.refreshableview"
android:id="@+id/main_refresh_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
rv:interceptAllMoveEvents="false"
>
<com.wangjie.refreshableview.NestScrollView android:layout_width="match_parent" android:layout_height="wrap_content"
android:fillViewport="true"
>
<TextView
android:id="@+id/main_tv"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:padding="20dp"
android:textSize="18sp"
android:text="Drop Down For Refresh\n\n\n\n\n\n\n\n\n\n\nDrop Down For Refresh\nDrop Down For Refresh\n\n\n\n\n\n\n\n\n\n\nDrop Down For Refresh\nDrop Down For Refresh\n\n\n\n\n\n\n\n\n\n\nDrop Down For Refresh\nDrop Down For Refresh\n\n\n\n\n\n\n\n\n\n\nDrop Down For Refresh"

注意：RefreshableView如果包含在ScrollView外面，需要设置属性“interceptAllMoveEvents”为false
