Android擷取系統應用資訊

我是仿照andorid launcher裡面的方法，現抽取如下：

[java]
Intent mainIntent = new Intent(Intent.ACTION_MAIN, null); 
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER); 
 
final PackageManager packageManager = getPackageManager(); 
List<ResolveInfo> apps = null; 
 
apps = packageManager.queryIntentActivities(mainIntent, 0); 
mNameList = new ArrayList<String>(); 
mDrawableList = new ArrayList<Drawable>(); 
mNameList.clear(); 
mDrawableList.clear(); 
if(apps != null && apps.size() > 0) 
{ 
    for (int i = 0; i < apps.size(); i++) 
    { 
        mNameList.add((String) apps.get(i).loadLabel(packageManager));//擷取應用程式名稱 
        mDrawableList.add(apps.get(i).loadIcon(packageManager));      //擷取應用圖片 
        System.out.println(apps.get(i).loadLabel(packageManager)); 
    } 
} 
這樣就可以過濾出category為Intent.CATEGORY_LAUNCHER的所有的應用了
