Java 保存Android中动态创建的复选框的复选框状态

我已经创建了listview，它包含安装在该设备上的所有应用程序。 当向用户显示已安装的应用程序时，每个应用程序都有相应的复选框。 用户单击多个复选框并保存相应的应用程序名称

我想要的是，当用户再次启动应用程序时，应该选中用户保存的应用程序的复选框

我该怎么做？有人能帮我吗？ 提前谢谢

这是密码

AppList.java

public class AppList extends Activity {
AppInfoAdapter adapter ;
AppInfo app_info[] ;

    super.onCreate(savedInstanceState);

    final ListView listApplication = (ListView)findViewById(R.id.listApplication);
    final Button b= (Button) findViewById(R.id.button001);
    final Context context = null;
    b.setOnClickListener(new OnClickListener()
    {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            StringBuilder result = new StringBuilder();
            for(int i=0;i<app_info.length;i++)
            {
                if(adapter.mCheckStates.get(i)==true)
                {

                                   result.append(app_info[i].applicationName).append(",");
                   // result.append(",");
                }

            }

            String playlists = result.toString();
            StoringClas.writeApps(AppList.this, playlists);
            //String[] po = playlists.split(",");
            //b.setText(po[2]+"o");

        }

    });

    ApplicationInfo applicationInfo = getApplicationInfo();
    PackageManager pm = getPackageManager();
    List<PackageInfo> pInfo = new ArrayList<PackageInfo>();
    pInfo.addAll(pm.getInstalledPackages(0));
    app_info = new AppInfo[pInfo.size()];

    int counter = 0;
    for(PackageInfo item: pInfo){
        try{

            applicationInfo = pm.getApplicationInfo(item.packageName, 1);

                     app_info[counter] = new AppInfo(pm.getApplicationIcon(applicationInfo), 
                             String.valueOf(pm.getApplicationLabel(applicationInfo)));


            System.out.println(counter);

        }
        catch(Exception e){
             System.out.println(e.getMessage());
        }

        counter++;
    }

   adapter = new AppInfoAdapter(this, R.layout.item_row, app_info);
    listApplication.setAdapter(adapter);

}}

Android中有很多方法可以在应用程序发布之间保存信息。Android网站提供了不同内置方式的绝佳概述：

一旦你选择了一种保存方式，如

SharedReference

或数据库，那么当你的应用程序启动时，你可以检查保存的信息并将其显示给用户。
