失敗傳遞結果ResultInfo {who = null，請求= 200，結果= -1，數據=意圖

我想從主要調用我的子活動。在此期間，我需要將linkedhashSet傳遞給它。在兒童活動中，我想對這個哈希集合執行一些操作，和點擊兒童活動中對話框的確定按鈕，我想將這個新的鏈接集合返回給pareent。失敗傳遞結果ResultInfo {who = null，請求= 200，結果= -1，數據=意圖

目前我使用下面的代碼在父母的活動，同時發送原始的HashSet：

Bundle bundle = new Bundle(); 
       bundle.putSerializable("keyThumbNails", thumbNailsLnkdhs); 

       Intent AndroidCustomGalleryActivityIntent = new Intent(parentActivity.this, childActivity.class); 
       childActivity.putExtras(bundle); 
       startActivityForResult(childActivity,200); 



Log.d(LOGGER, "ChildyActivityIntent called ");

它工作正常。我可以在兒童活動中接收這個哈希集，我可以對它進行操作。

我嘗試使用下面的代碼來發送新的HashSet：

new AlertDialog.Builder(this) 
      .setMessage(mymessage) 
      .setTitle(title) 

      .setNeutralButton(android.R.string.ok, 
      new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialog, int whichButton){ 
       Log.d(LOGGER, "AlertDialog neutral btn"); 
//     // the button was clicked 
        Bundle bundleToSend = new Bundle(); 
        bundleToSend.putSerializable("keyThumbNailsOfSelectedImages", SelectedThumbnailsPathsLnkdhs); 

        Intent SearchWebForWallPaperActivityIntent = new Intent(AndroidCustomGalleryActivity.this, SearchWebForWallPaperActivity.class); 
        SearchWebForWallPaperActivityIntent.putExtra("RESULT",bundleToSend); 
        setResult(Activity.RESULT_OK, SearchWebForWallPaperActivityIntent); 
        finish(); 
      } 
      }) 
      .show(); 
     }

這是正確shwon。

在父活動我使用下面的代碼收到此HashSet的......這段代碼有問題後，「得到包」記錄......

@Override 
    public void onActivityResult(int requestCode, int resultCode, Intent data) {  
     super.onActivityResult(requestCode, resultCode, data); 
     switch(requestCode) { 
     case (200) : { 
      if (resultCode == Activity.RESULT_OK) { 
       Log.d(LOGGER, "inside RESULT OK"); 
       //Bundle revievedBundle = this.getIntent().getExtras(); 
       Bundle recievedBundle = data.getExtras(); 
       Log.d(LOGGER, "got bundle"); 
      // if(recievedBundle.isEmpty()){ 
        //Log.d(LOGGER, "its empty"); 
       //} 
       SelectedThumbnailsPathsLnkdhs = (LinkedHashSet<String>) recievedBundle.getSerializable("keyThumbNailsOfSelectedImages"); 
      Log.d(LOGGER, "ThumbNailsLnkdhs size in SearchWebForWallPaperActivity intent: "+SelectedThumbnailsPathsLnkdhs.size()); 

      Toast.makeText(getApplicationContext(), 
         "ThumbNailsLnkdhs size in old intent: "+SelectedThumbnailsPathsLnkdhs.size(), Toast.LENGTH_LONG).show(); 

      } 
      break; 
     } 
     } 
    }

我嘗試了很多事情，搜索長讓它工作。但不可能成功:( 任何人都可以看看這個代碼，並幫助我嗎？

以下是logcat的痕跡：

顯示堆棧跟蹤信息，請 – 2012-03-10 19:13:35

編輯我的問題，並添加logcat的痕跡。謝謝 – adityag 2012-03-10 19:26:29

嗨，嗨，你爲什麼使用'putSerializable'？ – 2012-03-10 19:34:13

解決方案：

繪製SurfaceChanged期間的位圖，使用標記是否加載圖像

顯然，在MediaStore活動返回選擇後，SurfaceView尚未準備好立即進行繪製
