ApplicationAdapter,

public class ApplicationAdapter extends ArrayAdapter<ApplicationInfo> implements CompoundButton.OnCheckedChangeListener { 
    private List<ApplicationInfo> appsList = null; 
    private Context context; 
    private PackageManager packageManager; 
    SparseBooleanArray mCheckStates; 
    CheckBox chkSelect; 
    SharedPreferences.Editor editor; 
    ApplicationInfo applicationInfo; 
    int count; 
    String Pname; 
    AppInfoHolder holder; 

    public ApplicationAdapter(Context context, int textViewResourceId, 
           List<ApplicationInfo> appsList) { 
     super(context, textViewResourceId, appsList); 
     this.context = context; 
     this.appsList = appsList; 
     packageManager = context.getPackageManager(); 
     mCheckStates = new SparseBooleanArray(); 
     count=appsList.size(); 
    } 

    @Override 
    public int getCount() { 
     return ((null != appsList) ? appsList.size() : 0); 
    } 

    @Override 
    public ApplicationInfo getItem(int position) { 
     return ((null != appsList) ? appsList.get(position) : null); 
    } 

    @Override 
    public long getItemId(int position) { 
     return position; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     SharedPreferences sharedPrefs = context.getSharedPreferences("shared",Context.MODE_PRIVATE); 
     editor = sharedPrefs.edit(); 
     View view = convertView; 
     holder=null; 
     if (null == view) { 
      LayoutInflater layoutInflater = (LayoutInflater) context 
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      view = layoutInflater.inflate(R.layout.snippet_list_row, null); 
      holder=new AppInfoHolder(); 
      holder.chkSelect = (CheckBox) view.findViewById(R.id.checkbox); 
      holder.appName = (TextView) view.findViewById(R.id.app_name); 
      holder.packageName = (TextView) view.findViewById(R.id.app_paackage); 
      holder.iconview = (ImageView) view.findViewById(R.id.app_icon); 

      view.setTag(holder); 
     }else{ 
      holder=(AppInfoHolder)view.getTag(); 
     } 

     applicationInfo = appsList.get(position); 
     if (null != applicationInfo) { 


      holder.appName.setText(applicationInfo.loadLabel(packageManager)); 
      holder.packageName.setText(applicationInfo.packageName);    holder.iconview.setImageDrawable(applicationInfo.loadIcon(packageManager)); 
     } 

     Collections.sort(appsList, new ApplicationInfo.DisplayNameComparator(packageManager)); 
     holder.chkSelect.setTag(position); 


     holder.chkSelect.setChecked(sharedPrefs.getBoolean("CheckValue" + position, false)); 
     holder.chkSelect.setOnCheckedChangeListener(this); 

     return view; 
    } 
    public boolean isChecked(int position) { 
     return mCheckStates.get(position, false); 
    } 

    public void setChecked(int position, boolean isChecked) { 
     mCheckStates.put(position, isChecked); 
    } 

    public void toggle(int position) { 
     setChecked(position, !isChecked(position)); 

    } 
    @Override 
    public void onCheckedChanged(CompoundButton buttonView, 
           boolean isChecked) { 
    //save the checkbox values (true or false) 
     editor.putBoolean("CheckValue" + buttonView.getTag(), isChecked); 

     //total number of items in the list  
     editor.putInt("count",count); 
     editor.commit(); 
    } 

    static class AppInfoHolder{ 
     CheckBox chkSelect; 
     TextView appName; 
     TextView packageName; 
     ImageView iconview; 
    } 
} 

В адаптере приложений (в onCheckedChanged) можно сохранить значения флажок (истина или ложь), а общее кол элементы в виде списка (общее количество установленных приложений). Точно так же я хотел бы сохранить PACKAGE NAME всего приложения. Что я сделал, чтобы спасти это, используя один из указанных ниже двух методов,

1. editor.putString («имя» + buttonView.getTag(), applicationInfo.packageName); // (добавлено в onChecked changed)
2. editor.putString ("name" + position, holder.packageName.getText(). toString()); // (добавлено в getview)

Эти два файла сохраняют только некоторые имена пакетов или ничего. Пожалуйста, помогите мне сохранить все имена пакетов.

Примечание: положение и buttonView.getTag() значения 0,1,2, ... и т.д.

Answer 1

я изменил это в основной деятельности и теперь я получаю все имена пакетов без любой вопрос.

private List<ApplicationInfo> checkForLaunchIntent(List<ApplicationInfo> list) { 
      ArrayList<ApplicationInfo> applist = new ArrayList<ApplicationInfo>(); 
      i=0; 
      for (ApplicationInfo info : list) { 

       try { 

        if (null != packageManager.getLaunchIntentForPackage(info.packageName)) { 


         applist.add(info); 
         //str=info.loadIcon(packageManager).toString(); 

          editor.putString("name" + i, info.processName.toString()); 

         // results.add(info.loadLabel(packageManager).toString()); 
         i++; 
        } 
       } catch (Exception e) { 
        e.printStackTrace(); 
       } 

      } 
      editor.commit(); 
      return applist; 
     }
