Android 獲取系統應用信息

我是仿照andorid launcher裡面的方法，現抽取如下：

1. Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
2. mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
4. final PackageManager packageManager = getPackageManager();
5. List<ResolveInfo> apps = null;
7. apps = packageManager.queryIntentActivities(mainIntent, 0);
8. mNameList = new ArrayList<String>();
9. mDrawableList = new ArrayList<Drawable>();
10. mNameList.clear();
11. mDrawableList.clear();
12. if(apps != null && apps.size() > 0)
13. {
14. for (int i = 0; i < apps.size(); i++)
15. {
16. mNameList.add((String) apps.get(i).loadLabel(packageManager));//獲取應用名稱
17. mDrawableList.add(apps.get(i).loadIcon(packageManager)); //獲取應用圖片
18. System.out.println(apps.get(i).loadLabel(packageManager));
19. }
20. }

這樣就可以過濾出category為Intent.CATEGORY_LAUNCHER的所有的應用了
