在列表视图中一次显示 10 个项目，在滚动一段时间后显示接下来的 10 个项目，依此类推

问：

我想在列表视图中显示手机中所有已安装的应用程序。但是，我想一次显示 10 个应用程序。现在，当用户滚动时，应该显示另外 10 个（来自其余应用程序），依此类推。

这是我的代码

    List<PackageInfo> packageList = getPackageManager().getInstalledPackages(0);
    
            List<String> appNames = new ArrayList<>();
    
            for (PackageInfo packageInfo : packageList) {
                if ((packageInfo.applicationInfo.flags & android.content.pm.ApplicationInfo.FLAG_SYSTEM) == 0) {
                 appNames.add(packageInfo.applicationInfo.loadLabel(getPackageManager()).toString());
                }
            }
    
            ArrayAdapter adapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, appNames);
            listView.setAdapter(adapter);

任何建议如何实现此功能？

我已经实现了 RecyclerView 而不是列表视图，这是代码

private int visibleThreshold = 10;

        appNames = new ArrayList<>();
        adapter = new AppListAdapter(appNames);
        recyclerView.setAdapter(adapter);

        recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
                super.onScrolled(recyclerView, dx, dy);

                totalItemCount = layoutManager.getItemCount();
                lastVisibleItem = layoutManager.findLastVisibleItemPosition();

                if (!loading && totalItemCount <= (lastVisibleItem + visibleThreshold)) {
                    // Load the next batch of applications
                    loadMoreApps();
                    loading = true;
                }
            }
        });

        loadMoreApps();
    }

    private void loadMoreApps() {

        int start = appNames.size();
        int end = start + 10;

        List<PackageInfo> packageList = getPackageManager().getInstalledPackages(0);
        for (int i = start; i < Math.min(end, packageList.size()); i++) {
            PackageInfo packageInfo = packageList.get(i);
            if ((packageInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 0) {
                appNames.add(packageInfo.applicationInfo.loadLabel(getPackageManager()).toString());
            }
        }

        adapter.notifyDataSetChanged();
        loading = false;
    }
}
