解析对象没有被删除（Android）

标签： android parse-platform

我正在尝试从我的parse.com类中删除一个对象＆＃34; GameScore＆＃34;其中playerName等于当前玩家名称。我成功检索了对象但是deleteInBackground函数对我不起作用。（对象没有从parse.com类中删除。我是新手解析和android两者。有人可以帮忙。

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

        @Override
        public void onClick(View v) {

            //String myname = worldpopulationlist.get(position).getName();

            ParseQuery<ParseObject> query = ParseQuery.getQuery("GameScore");
            query.whereEqualTo("playerName", worldpopulationlist.get(position).getName());
            query.getFirstInBackground(new GetCallback<ParseObject>() {

                @Override
                public void done(ParseObject object, ParseException e) {
                    // TODO Auto-generated method stub
                    if (object == null) {
                        Toast.makeText(context,"  not found",
                                Toast.LENGTH_SHORT).show();
                        } else {
                            object1.deleteInBackground(new DeleteCallback() {
                                           public void done(ParseException e) {
                                                 if (e == null) {
                                                     Toast.makeText(context,"  deleted",
                                                                Toast.LENGTH_SHORT).show();
                                                 } else {
                                                     Toast.makeText(context,"  not deleted",
                                                                Toast.LENGTH_SHORT).show();
                                                     e.printStackTrace();

                                                 }
                                               }
                                             });

                        }
                    }

            });
            Intent intent = new Intent(context, MainActivity.class);
            intent.setFlags( Intent.FLAG_ACTIVITY_NO_HISTORY);
            context.startActivity(intent);

        }


    });

这是错误日志。日志的第一行显示未找到的对象，但是当我使用object.getObjectId（）方法时。它返回对象的正确objectId。

我遇到了类似的问题，我的问题是Parse ACL权限。

在类中，您最初创建对象的位置（不是要删除对象的类）。设置写权限如下：

    ParseACL defaultACL = new ParseACL();
    defaultACL.setPublicReadAccess(true);
    defaultACL.setPublicWriteAccess(true); //objects created are writable
    ParseACL.setDefaultACL(defaultACL, true);

可能是deleteInBackground()正在返回错误，或者（在Android处理此方式时不确定）它在进行删除之前被垃圾收集。

考虑向删除添加回调，以至少记录删除中的成功/错误。
