I,CustomListView description:You can pull down and refresh, pull up and load, and call back the horizontal sliding interface,
/**
* Functions are similar to ListView, and the following are the features of Tianji:
* 1. pull-down refresh and load up to implement the CustomListView. OnPullListener Interface
* 3. Slide switching to implement the CustomListView. OnSlideListener Interface

Ii. CustomListFragment Function Description: pull-down and refresh, pull-up and load, horizontal sliding interface callback,

It has all ListFragment functions, the drop-down refresh and pull-up loading functions of the Tianji, and the Slide sliding switching callback interface;


Usage:
You can use your own Fragment to inherit CustomListFragment and rewrite the onCreateView function:
1. Return custom_list_fragment_content.xml Layout directly,
For example
@ Override
Public View onCreateView (LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState ){
If (container = null ){
// We have different layouts, and in one of them this
// Fragment's containing frame doesn't exist. The fragment
// May still be created from its saved state, but there is
// No reason to try to create its view hierarchy because it
// Won't be displayed. Note this is not needed -- we cocould
// Just run the code below, where we wocould create and return
// The view hierarchy; it wocould just never be used.
Return null;
}
View root = inflater. inflate (R. layout. custom_list_fragment_content, null );
Return root;
}


2. You need to add the custom layout of the control myfragment. xml:
(Including custom_list_fragment_content.xml)
Xmlns: android = "http://schemas.android.com/apk/res/android"
Android: orientation = "vertical"
Android: layout_width = "match_parent"
Android: layout_height = "match_parent"
>
Android: id = "@ + id/last_synctime_message"
Android: layout_width = "match_parent"
Android: layout_height = "@ dimen/error_message_height"
Android: paddingLeft = "8dip"
Android: paddingRight = "8dip"
Android: gravity = "right | center_vertical"
Android: text = "@ string/no_last_synctime"
Android: singleLine = "true"
Android: ellipsize = "end"
Android: background = "@ color/synctime_bar_background"
Android: visibility = "gone"
/>
Android: layout_width = "match_parent"
Android: layout_height = "1px"
Android: background = "? Android: attr/listDivider "/>

Layout = "@ layout/custom_list_fragment_content"
Android: id = "@ + id/list_panel"
Android: layout_width = "match_parent"
Android: layout_height = "0dip"
Android: layout_weight = "1"
/>






Then,
Public View onCreateView (LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState ){
View root = inflater. inflate (R. layout. myfragment, null );
Return root;
}
