Question

我正在开发一个Android应用程序，它将显示手机中安装的所有应用程序，当点击特定应用程序时，它应该只显示该应用程序的权限。我使用包管理器来获取apk安装的所有细节的详细信息。代码的一部分在这里：

    PackageManager packageManager = context.getPackageManager();
    List<PackageInfo> applist = packageManager.getInstalledPackages(0);
    Iterator<PackageInfo> it = applist.iterator();
    while (it.hasNext()) {
        PackageInfo pk = (PackageInfo) it.next();
        PackageInfo pk1 = (PackageInfo) it.next();



        if ((pk.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
            // Log.v("System app using internet = ",""+ pk.applicationInfo.loadLabel(packageManager));
            String p = pk.applicationInfo.loadLabel(packageManager).toString();

            if (PackageManager.PERMISSION_GRANTED == packageManager.checkPermission(Manifest.permission.CAMERA, pk.packageName))
                //results.add("" +"\n"+pk.applicationInfo.loadLabel(packageManager));





            {
                //Drawable appicon = getPackageManager().getApplicationIcon("com.google.maps");
                results.add("" + "\n" + pk.applicationInfo.loadLabel(packageManager));
            }
            if (PackageManager.PERMISSION_GRANTED == packageManager.checkPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE, pk.packageName))
                results1.add("" +"\n"+pk1.applicationInfo.loadLabel(packageManager));
        }

    }

在列出应用程序时，我应该在应用程序名称后面加上图标。

Icon and application name example 我应该如何修改此代码，以便获得所需的输出。
