Question

我试图找到一张表，我试试这样的所有细节 -

ParseQuery<ParseObject> query2 = ParseQuery.getQuery("ProfileData");
    query2.findInBackground(new FindCallback<ParseObject>() {
        @Override
        public void done(List<ParseObject> profileList, ParseException e) {
            if (e == null) {
                if (profileList.size() > 0) {
                    for (int i = 0; i < profileList.size(); i++) {
                        ParseObject p = profileList.get(i);

                        Log.d("ParseQuery", "objectId: " + p.getString("objectId"));
                    }
                }
            } else {
                Log.d("score", "Error: " + e.getMessage());
            }
        }
    });

但我得到了

错误：i / o失败

表格如下 -

View service 我做错了吗？

Answer 1

1）在继续之前，只需从parse.com检查您的表名密钥名称是否正确。

2）使用try {} catch（Throwable t）{}包围代码，以避免任何异常停止您的应用。

3）只需尝试调试即可找到确切的问题并提供更多细节。因此，您可以获得更好的解决方案。

4）首选android studio进行更好的调试。
