Android之在launcher里面动态加载桌面图标

1、在手机桌面加载图标方式

         1）、动态加载

  

   

    

     

    
    

     

      Launcher.java
     
    
   

    

     

    
    

     

      private void addSourceList() {
     
    
   

    

     

    
    

     

       Intent launchIntent = new Intent(this, RcGrpActivity.class);
     
    
   

    

     

    
    

     

       launchIntent.setAction(Intent.ACTION_MAIN);
     
    
   

    

     

    
    

     

       launchIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       Intent addIntent = new Intent();
     
    
   

    

     

    
    

     

       addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, launchIntent);
     
    
   

    

     

    
    

     

       addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.source_list));
     
    
   

    

     

    
    

     

       addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
     
    
   

    

     

    
    

     

       ShortcutIconResource.fromContext(this, R.drawable.keycard));
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       ShortcutInfo shortcut = mModel.infoFromShortcutIntent(this, addIntent);
     
    
   

    

     

    
    

     

       shortcut.deletable = false;
     
    
   

    

     

    
    

     

       shortcut.titleResource = getResources().getResourceName(R.string.source_list);
     
    
   

    

     

    
    

     

       shortcut.presetItemId = getResources().getInteger(R.integer.preset_source_list_icon);
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       if (LauncherModel.presetItemExists(this, shortcut.presetItemId)) {
     
    
   

    

     

    
    

     

       return;
     
    
   

    

     

    
    

     

       }
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       ArrayList<ItemInfo> list = new ArrayList<ItemInfo>();
     
    
   

    

     

    
    

     

       list.add(shortcut);
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       mModel.addAndBindAddedApps(this, list, new ArrayList<AppInfo>(), true);
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       }
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      LauncherModel.java
     
    
   

    

     

    
    

     

       static boolean presetItemExists(Context context, int presetItemId) {
     
    
   

    

     

    
    

     

       final ContentResolver cr = context.getContentResolver();
     
    
   

    

     

    
    

     

       Cursor c = cr.query(LauncherSettings.Favorites.CONTENT_URI,
     
    
   

    

     

    
    

     

       new String[]{"title"},
     
    
   

    

     

    
    

     

       "presetItemId=?",
     
    
   

    

     

    
    

     

       new String[]{Integer.toString(presetItemId)},
     
    
   

    

     

    
    

     

       null);
     
    
   

    

     

    
    

     

       if (c == null) {
     
    
   

    

     

    
    

     

       return false;
     
    
   

    

     

    
    

     

       }
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

       try {
     
    
   

    

     

    
    

     

       return c.moveToFirst();
     
    
   

    

     

    
    

     

       } finally {
     
    
   

    

     

    
    

     

       c.close();
     
    
   

    

     

    
    

     

       }
     
    
   

    

     

    
    

     

       }
     
    
  
 

    优点：不需要平板适配

     2）、静态加载

     通过xml文件加载

      1、xml文件

  

   

    

     

    
    

     
 <?xml version="1.0" encoding="utf-8"?>
     
    
   

    

     

    
    

     
 <favorites xmlns:launcher="http://schemas.android.com/apk/res-auto">
     
    
   

    

     

    
    

     
 <shortcut
     
    
   

    

     

    
    

     
 launcher:uri="#Intent;action=com.sangfor.action.ACTION_OPEN_RESOURCE;category=android.intent.category.DEFAULT;end"
     
    
   

    

     

    
    

     
 launcher:iconRes="@drawable/ic_setting_app"
     
    
   

    

     

    
    

     
 launcher:titleRes="@string/source_list"
     
    
   

    

     

    
    

     
 launcher:container="-100"
     
    
   

    

     

    
    

     
 launcher:screen="0"
     
    
   

    

     

    
    

     
 launcher:x="2"
     
    
   

    

     

    
    

     
 launcher:y="2"
     
    
   

    

     

    
    

     
 launcher:deletable="false"
     
    
   

    

     

    
    

     
 launcher:presetItemId="@integer/preset_settings_icon"
     
    
   

    

     

    
    

     

       />
     
    
   

    

     

    
    

     
 </favorites>
     
    
  
 

     2、  AndroidManifest.xml

  

   

    

     

    
    

     
 <activity
     
    
   

    

     

    
    

     
 android:name="com.sangfor.vpn.client.phone.resource.RcGrpActivity"
     
    
   

    

     

    
    

     
 android:configChanges="orientation|keyboardHidden|screenSize"
     
    
   

    

     

    
    

     
 android:label="@string/about"
     
    
   

    

     

    
    

     
 android:screenOrientation="behind"
     
    
   

    

     

    
    

     
 android:theme="@android:style/Theme.Light.NoTitleBar" >
     
    
   

    

     

    
    

     
 <intent-filter>
     
    
   

    

     

    
    

     
 <action android:name="com.sangfor.action.ACTION_OPEN_RESOURCE" />
     
    
   

    

     

    
    

     
 <category android:name="android.intent.category.DEFAULT" />
     
    
   

    

     

    
    

     
 </intent-filter>
     
    
   

    

     

    
    

     
 </activity>
