Android third-party framework Xlistview use

Now the pull-up refresh, drop-down load more is already a voluminous app standard

Recently, there is a related need to learn a bit, or the old saying that everything is on their own

It is not a good thing to do, time and effort not to say that may be doing a useless work, but their own research and study

It's still a necessity. Not to mention the third-party framework I used called Xlistview. This is its managed address:

Https://github.com/Maxwin-z/XListView-Android

After downloading it down

Copy the extracted content to your own project (you can build a package to store it, I did it)

Note that layout,string and drawable also have several corresponding files, which also need to go into the examination.

Then write the layout for the ListView

Note: <com.xxxxxxx the location of your own corresponding file xxx>

<?XML version= "1.0" encoding= "Utf-8"?><LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent"android:orientation= "vertical"Android:background= "#f0f0f0">    <TextViewAndroid:layout_width= "Fill_parent"Android:layout_height= "Wrap_content"Android:text= "@string/hello" />    <Com.example.guwie.yaoren.ui.view.XListViewAndroid:id= "@+id/xlistview"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent"Android:cachecolorhint= "#00000000">    </Com.example.guwie.yaoren.ui.view.XListView></LinearLayout>


Write the corresponding Java file for the layout file

The method of Myadapter here is custom, please refer to Xu Dashen's "Android must learn-baseadapter use and optimization" for details.
The above method is about the use of volley please Baidu Operation effect:
