如何在拍攝由相機意圖拍攝的各種標記時顯示圖像？

Question

我正嘗試在用戶點擊的位置顯示相機拍攝的圖像的標記（縮略圖）的全尺寸圖像。但到目前爲止，圖像會顯示，但始終顯示拍攝的最新圖像，而不是之前拍攝第一個標記時拍攝的圖像。

這裏是我到目前爲止的代碼：

public void onMapLongClick(final LatLng point) { 
     poinOnMap=point; 

     googleMap.setOnInfoWindowClickListener(new OnInfoWindowClickListener() { 

      @Override 
      public void onInfoWindowClick(Marker marker) { 
       Intent intent = new Intent(); 
       intent.setAction(Intent.ACTION_VIEW); 
       Uri selectedImage = intent.getData(); 
       String[] filePathColumn = {MediaStore.Images.Media.DATA}; 
       Cursor cursor = getContentResolver().query(
            selectedImage, filePathColumn, null, null, null); 
       cursor.moveToFirst(); 
       int columnIndex = cursor.getColumnIndex(filePathColumn[0]); 
       String fileUri = cursor.getString(columnIndex); 
       cursor.close(); 
       bitmap = BitmapFactory.decodeFile(fileUri); 
       Uri imgUri = Uri.parse("file://" + bitmap + fileUri); 
       intent.setDataAndType(imgUri, "image/*"); 
       startActivity(intent); 
      return; 
      } 
     }); 
    getApplicationContext().getDir(
       getResources().getString(R.string.app_name), MODE_PRIVATE); 

      fileUri = Uri.fromFile(new File((Environment.getExternalStorageDirectory() + 
        "/" +getResources().getString(R.string.app_name)),new Date().getTime() + ".jpg")); 
      Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
      takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); 
      startActivityForResult(takePictureIntent,TAKE_PICTURE); 
    } 

     public void onActivityResult(int requestCode, int resultCode, Intent data) { 
      if (requestCode == TAKE_PICTURE && resultCode == RESULT_OK) { 

        try { 
         GetImageThumbnail getImageThumbnail = new GetImageThumbnail(); 
         bitmap = getImageThumbnail.getThumbnail(fileUri, this); 
        } catch (FileNotFoundException e1) { 
         e1.printStackTrace(); 
        } catch (IOException e1) { 
         e1.printStackTrace(); 
        } 

誰能告訴我什麼，我做錯了什麼？

烏里selectedImage是空

Intent intent = new Intent(); 
      intent.setAction(Intent.ACTION_VIEW); 
      Uri selectedImage = intent.getData();
