如何在活动重新启动时将意图附加项传递给onactivity结果？

Question

我正在写一个android应用程序。需要传递int值。我有一个listview它有contextmenu.I必须启动Intent.Action_Call。当我开始我的意图。我的应用程序将会背景。当意图完成后，我的应用程序开始调查。我的问题是;我没有得到用户的点击位置。我试图插入putExtra但在onActivityResult void不接受我用户的点击位置和值的值为零。如何我能得到它吗 ？

public boolean onContextItemSelected(MenuItem item) { 
      AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo(); 

     selectedPosition = info.position; 

    //in here , this value is true. 
      Toast.makeText(AnaMenu.this, String.valueOf(selectedPosition), Toast.LENGTH_LONG).show(); 

      switch (item.getItemId()) { 
       case MENU_Ara: 

        Intent i = getIntent(); 
        final ArrayList<String> secilmis = i.getStringArrayListExtra("listem"); 

        Intent ara = new Intent(Intent.ACTION_CALL); 
        ara.setData(Uri.parse("tel:" + secilmis.get(info.position).toString())); 


        ara.putExtra("selected", selectedPosition); 





        startActivityForResult(ara, AnketDegerlendirmesi); 






        return true; 
      } 


      return super.onContextItemSelected(item); 
     } 




    protected void onActivityResult(final int requestCode, int resultCode, final Intent data) { 

      if (requestCode == AnketDegerlendirmesi){ 
       Toast.makeText(AnaMenu.this,String.valueOf(selectedPosition),Toast.LENGTH_LONG).show(); 

       final AlertDialog.Builder mBuilder = new AlertDialog.Builder(AnaMenu.this); 
       mBuilder.setTitle("Deger"); 
       mBuilder.setIcon(R.drawable.ic_build_black_24dp); 
       mBuilder.setMultiChoiceItems(afteractivitydialogitems, dialogcheckeditems, new DialogInterface.OnMultiChoiceClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int position, boolean isChecked) { 



         if (isChecked){ 
     mUserselecteditems.add(Integer.valueOf(dialogdegerleri[position])); 
    } 
    if (!isChecked) { 
    if (mUserselecteditems.contains(Integer.valueOf(dialogdegerleri[position]))){ 
     mUserselecteditems.remove(Integer.valueOf(dialogdegerleri[position])); 
    } 
    } 
    } 
       }); 

       mBuilder.setCancelable(false); 
       mBuilder.setPositiveButton("Tamamdır.", new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int which) { 


         String items = ""; 
         toplamaislemi = 0; 
         for (int item : mUserselecteditems) { 
          items += "-" + item + "\n"; 

          toplamaislemi = toplamaislemi + item; 



    //When i want to get this value.Value is always zero(0) 
         String returnString = data.getStringExtra("selected"); 
         kullanıcısayıdegerlistesi.remove(String.valueOf(returnString)); 
         kullanıcısayıdegerlistesi.add(Integer.valueOf(returnString),String.valueOf(toplamaislemi)); 
         oyunTextView.notifyDataSetChanged(); 

        } 
       } )    .show(); 


      } 


      super.onActivityResult(requestCode, resultCode, data); 
     } 

Answer 1

首先，把这个onContextItemSelected

SharedPreferences settings = getSharedPreferences("PREFS_NAME", MODE_PRIVATE); 
       SharedPreferences.Editor editor = settings.edit(); 
editor.clear(); 

       editor.putInt("kelime", selectedPosition); 

       editor.commit(); 

安顿下来以上的鳕鱼后，设置onActivityResult

SharedPreferences settings = getSharedPreferences("PREFS_NAME", MODE_PRIVATE); 
        int selec = settings.getInt("kelime",selectedPosition); 

最后，设置适配器同样无效：

kullanıcısayıdegerlistesi.remove(selec); 
         kullanıcısayıdegerlistesi.add(selec ,String.valueOf(sonuc)); 

Answer 2

这听起来像你希望能够把这个：

Intent i = new Intent(...); 
i.putExtra("some_key", someValue); 
startActivityForResult(i, requestCode); 

再后来，当您收到结果：

protected void onActivityResult(... Intent data) { 
    data.getExtra("some_key"); // should be `someValue` from above 
} 

不幸的是，这是不是怎么运行的。 onActivityResult()的Intent data参数与您用于启动该活动的Intent不同。您开始的活动可以完全控制data意图是否为非空，以及其中的内容。

通常对于公共APIs，有关于您可以期望在data意图内有什么的文档。
