Android 获取系统应用信息

我是仿照andorid launcher里面的方法，现抽取如下：

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));//获取应用名称 mDrawableList.add(apps.get(i).loadIcon(packageManager)); //获取应用图片 System.out.println(apps.get(i).loadLabel(packageManager)); } }

这样就可以过滤出category为Intent.CATEGORY_LAUNCHER的所有的应用了
