解析对象不会删除

Question

我使用解析为巴斯，我用下面的代码删除。但明天我才知道，这段代码是不工作的对象。

@Override 
     public void onClick(View view) { 
      new AlertDialog.Builder(context).setIcon(R.drawable.main).setTitle("Delete this product ?") 
        .setMessage("Are you sure you want to Delete this product ?").setPositiveButton("Yes", new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialogInterface, int i) { 



        ParseQuery<ParseObject> query = ParseQuery.getQuery("VendorInv"); 
        query.whereEqualTo("objectId", details.getObjectId()); 
        query.getFirstInBackground(new GetCallback<ParseObject>() { 
         @Override 
         public void done(ParseObject object, ParseException e) { 
          try { 
           object.delete();  // fixed part 
           object.saveInBackground(new SaveCallback() { // fixed part 
            @Override 
            public void done(ParseException e) { 

             if (e == null) { 
              vendorDetailsList.remove(position); 
              notifyItemRemoved(position); 
              notifyItemRangeChanged(position, vendorDetailsList.size()); 
              count.setText(String.valueOf(vendorDetailsList.size()) + "/" + totalNo + " items are Online"); 
              Toast.makeText(context, "Deleted", Toast.LENGTH_SHORT).show(); 
             } 
            } 
           }); 
          } catch (ParseException e1) { 
           Log.i("sand", e1.toString()); 
          } 
         } 
        }); 
       } 

      }).setNegativeButton("No", null).show(); 


     } 

    }); 

} 

然后，当解析机器人的贡献者所述比我固定下方的这部分代码

holder.cross.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View view) { 
       new AlertDialog.Builder(context).setIcon(R.drawable.main).setTitle("Delete this product ?") 
         .setMessage("Are you sure you want to Delete this product ?").setPositiveButton("Yes", new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialogInterface, int i) { 


         ParseQuery<ParseObject> query = ParseQuery.getQuery("VendorInv"); 
         query.whereEqualTo("objectId", vendorDetailsList.get(position).getObjectId()); 
         query.getFirstInBackground(new GetCallback<ParseObject>() { 
          @Override 
          public void done(ParseObject object, ParseException e) { 
/* this part is changed */        object.deleteInBackground(new DeleteCallback() { 
            @Override 
            public void done(ParseException e) { 
             if (e == null) { 
              Log.i("sand", vendorDetailsList.get(position).getObjectId()); 
              vendorDetailsList.remove(position); 
              notifyItemRemoved(position); 
              notifyItemRangeChanged(position, vendorDetailsList.size()); 
              count.setText(String.valueOf(vendorDetailsList.size()) + "/" + totalNo + " items are Online"); 
              Toast.makeText(context, "Deleted", Toast.LENGTH_SHORT).show(); 
             } else { 
              Toast.makeText(context, "Not Deleted please check your network connection", Toast.LENGTH_SHORT).show(); 
             } 
            } 
           }); 

          } 
         }); 


        } 

       }).setNegativeButton("No", null).show(); 


      } 

     }); 

吐司是印刷删除，但仍然在对象数据库不会被删除。 我不知道我要去的地方错了，但是这并没有帮助我在删除对象 任何帮助，将不胜感激

配置您的VendorInv类在服务器上是“公共的读取和写入启用” 和使用下面的代码：

ParseQuery<ParseObject> query = ParseQuery.getQuery("VendorInv"); 
    query.getInBackground(vendorDetailsList.get(position).getObjectId(), new GetCallback<ParseObject>() { 
     @Override 
     public void done(ParseObject object, ParseException e) { 
      if (object != null) { 
       object.deleteInBackground(new DeleteCallback() { 
        @Override 
        public void done(ParseException e) { 
         if (e == null) { 
          Log.i("sand", vendorDetailsList.get(position).getObjectId()); 
          vendorDetailsList.remove(position); 
          notifyItemRemoved(position); 
          notifyItemRangeChanged(position, vendorDetailsList.size()); 
          count.setText(String.valueOf(vendorDetailsList.size()) + "/" + totalNo + " items are Online"); 
          Toast.makeText(context, "Deleted", Toast.LENGTH_SHORT).show(); 
         } else { 
          Toast.makeText(context, "Not Deleted please check your network connection", Toast.LENGTH_SHORT).show(); 
         } 
        } 
       }); 
      } 
     } 
    });
