1. Introduction to favorites on the desktop

The launcher desktop has four elements in the middle, which are the window widgets of a clock. The following lines are respectively a camera, an Amazon bookmarks, and a folder (the folder contains settings and clock ).

In the code, they are all favorites: appwidget, application, shortcut, and folder.

Favorites is stored in the database.

4. Add the default favorites to the desktop

The default favorite on launcher is defined in launcher2 \ res \ XML \ default_workspace.xml. (Launcher2 \ res \ xml-sw600dp \ default_workspace.xml, launcher2 \ res \ xml-sw720dp \ default_workspace.xml)

<?xml version="1.0" encoding="utf-8"?><favorites xmlns:launcher="" >    <appwidget        launcher:className=""        launcher:packageName=""        launcher:screen="4"        launcher:spanX="2"        launcher:spanY="2"        launcher:x="2"        launcher:y="0" />    <favorite        launcher:className=""        launcher:packageName=""        launcher:screen="4"        launcher:x="1"        launcher:y="3" />    <shortcut        launcher:icon="@drawable/ic_home_voice_search_holo"        launcher:screen="4"        launcher:title="@string/application_name"        launcher:uri=";docId=1000626391"        launcher:x="2"        launcher:y="3" />    <folder        launcher:icon="@drawable/ic_launcher_home"        launcher:screen="4"        launcher:title="@string/folder_name_format"        launcher:x="3"        launcher:y="3" >        <favorite            launcher:className=""            launcher:packageName="" />        <favorite            launcher:className=""            launcher:packageName="" />    </folder>    <!-- Hotseat (We use the screen as the position of the item in the hotseat) -->    <favorite        launcher:className=""        launcher:container="-101"        launcher:packageName=""        launcher:screen="4"        launcher:x="4"        launcher:y="0" /></favorites>

5. Tool attachment and introduction

I wrote a program to help generate default_workspace.xml. Unfortunately, the program does not support shortcut and folder.


Before adding an application or widget to the launcher, you need to find the package name, class name, and position, and then manually add it to the code. Now, you only need to drag the Add button on the desktop and run the program to generate a layout file for the current desktop application and widget and save it in/mnt/sdcard/default_workspace.xml. Replace packages \ apps \ launcher2 \ res \ xml-sw720dp \ default_workspace.xml.
