我找到了ParceledListSlicehere的代码，以及它实现here的Parcelable接口的代码。看起来它在内部使用了某种形式的数组，所以你应该能够迭代它。我不能说这对你是否有帮助，因为我对这些库不是很熟悉，但我希望这是个起点祝你好运！

您可以应用您在第一次EDIT和EDIT 2中提到的方法，并使用Android的shell，因为您提到您的设备具有root权限。
顺便说一下，我不熟悉您正在使用的“stericson”库，但我同意利用现有库使您的生活更轻松;我使用的是libsuperuser。否则，你可以自己编写代码来使用Process等运行shell命令（但是在处理错误输出、关闭对象等方面需要考虑很多事情）。

private List<String> listAllInstalledApps(){
    String user = "0"; //can modify to iterate over all users 
    if (Shell.SU.available()) {
        //grab user installed package names
        List<String> output =
            Shell.SU.run("pm list packages --user " + user + " -3");
        StringBuilder csvBuilder = new StringBuilder();

        for(String item : output){
            csvBuilder.append(item);
            csvBuilder.append(", ");
        }
        Log.info(TAG, "Obtained installed apps: " + csvBuilder.toString());
        return output;
    }
    return new ArrayList<>();
}

当然，你也可以根据需要使用其他参数来pm，比如-e, -d参见documentation。
提取包名后，使用 dumpsys 获取所有必需的信息（如ApplicationInfo中所包含的信息）

//package names extracted from List<String> you returned earlier
for( String name : packageNames ){
    List<String> appInfo =
            Shell.SU.run("dumpsys package " + name);
    //search appInfo for info you need e.g. grantedPermissions, targetSdk...
}

如果您有专门需要此对象类型的下游代码，则根据需要创建ApplicationInfo对象

ApplicationInfo info = new ApplicationInfo();
info.uid = uid;
info.processName = processName;
info.className = classname;
info.packageName = packageName;
info.minSdkVersion = minSdkVersion;
//etc...

（ApplicationInfo类的字段是公共的）。这也适用于PackageInfo，它是一个包含ApplicationInfo字段的对象，另外它包含安装时间等的详细信息，这些也是您可以从dumpsys输出中提取的详细信息。因此您可以根据需要创建一个数组，并可以使用新的ApplicationInfo对象进行填充。

如果您能够访问隐藏的API，因为您是平台应用程序或正在使用内省（具有正确的权限！），您可以简单地使用UserManager.getUsers()和PackageManager. getInstalledApplicationsAsUser()：

Set<ApplicationInfo> installedApplications = new HashSet<>();
for (UserInfo user : getSystemService(UserManager.class).getUsers()) {
    installedApplications.addAll(getPackageManager().getInstalledApplicationsAsUser(PackageManager.GET_META_DATA, user.id));
}

private static JSONArray getAllAppNames() {
        JSONArray appNameList = new JSONArray();
        List<PackageInfo> packs = GlobalApplication.getContextOfApplication().getPackageManager().getInstalledPackages(0);
        for (int i = 0; i < packs.size(); i++) {
            PackageInfo p = packs.get(i);
            if ((!isSystemPackage(p))) {
                String appName = p.applicationInfo.loadLabel(GlobalApplication.getContextOfApplication().getPackageManager()).toString();
                appNameList.put(appName);
            }
        }
        return appNameList;
    }

    private static boolean isSystemPackage(PackageInfo pkgInfo) {
        return (pkgInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0;
    }

这应该或多或少解决了你的基本问题

以编程方式获取已安装的应用程序列表
添加代码到activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/rl"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="16dp"
    tools:context=".MainActivity"
    android:background="#8fa485">

    <ListView
        android:id="@+id/lv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

</RelativeLayout>

并将代码添加到MainActivity.java

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Get the application context
        mContext = getApplicationContext();

        // Get the activity
        mActivity = MainActivity.this;

        // Get the widgets reference from XML layout
        mRelativeLayout = (RelativeLayout) findViewById(R.id.rl);
        mListView = (ListView) findViewById(R.id.lv);

        // Initialize a new Intent which action is main
        Intent intent = new Intent(Intent.ACTION_MAIN,null);

        // Set the newly created intent category to launcher
        intent.addCategory(Intent.CATEGORY_LAUNCHER);

        // Set the intent flags
        intent.setFlags(
                Intent.FLAG_ACTIVITY_NEW_TASK|
                        Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED
        );

        // Generate a list of ResolveInfo object based on intent filter
        List<ResolveInfo> resolveInfoList = getPackageManager().queryIntentActivities(intent,0);

        // Initialize a new ArrayList for holding non system package names
        List<String> packageNames = new ArrayList<>();

        // Loop through the ResolveInfo list
        for(ResolveInfo resolveInfo : resolveInfoList){
            // Get the ActivityInfo from current ResolveInfo
            ActivityInfo activityInfo = resolveInfo.activityInfo;

            // If this is not a system app package
            if(!isSystemPackage(resolveInfo)){
                // Add the non system package to the list
                packageNames.add(activityInfo.applicationInfo.packageName);
            }
        }

        // Initialize an ArrayAdapter using non system package names
        ArrayAdapter adapter = new ArrayAdapter<String>(
                mContext,
                android.R.layout.simple_list_item_1,
                packageNames
        );

        // DataBind the ListView with adapter
        mListView.setAdapter(adapter);

        // Set an item click listener for the ListView widget
        mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                // Get the ListView selected item
                String selectedItem = (String) adapterView.getItemAtPosition(i);

                // Display a Toast notification for clicked item
                Toast.makeText(mContext,"CLICKED : " + selectedItem,Toast.LENGTH_SHORT).show();

                // Get the intent to launch the specified application
                Intent intent = getPackageManager().getLaunchIntentForPackage(selectedItem);
                if(intent != null){
                    startActivity(intent);
                }else {
                    Toast.makeText(mContext,selectedItem + " Launch Error.",Toast.LENGTH_SHORT).show();
                }
            }
        });

   }

    // Custom method to determine an app is system app
    private boolean isSystemPackage(ResolveInfo resolveInfo){
       return ((resolveInfo.activityInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0);
    }
}

你可以很容易地看到安装在手机上的应用程序的图标，只需付出一点努力，并添加ImageView。
