微调错误＆QUOT;旋转接头视图类型数量必须是1＆QUOT; [英] Spinner Error "Spinner adapter view type count must be 1"

问题描述

我在我的应用程序中使用Parse.com当我使用ParseQueryAdapter在片段检索数据并传递到一个微调的错误，因为

  java.lang.IllegalArgumentException：如果微调适配器视图类型数量必须是1
 

和应用程序停止。但是，如果我尝试ArrayAdapter它的工作原理。可能是什么问题？

ParseQueryAdapter code：

  ParseQueryAdapter.QueryFactory＆LT;的parseObject＆GT; spnQuery =
            新ParseQueryAdapter.QueryFactory＆LT;的parseObject＆GT;（）{
                公共ParseQuery创建（）{
                    ParseQuery查询=新ParseQuery（tableName值）;
                    返回查询;
                }
            };
    ParseQueryAdapter＆LT;的parseObject＆GT;适配器=新ParseQueryAdapter＆LT;的parseObject＆GT;（getActivity（）getApplicationContext（），spnQuery。）;
    adapter.setTextKey（COLUMNNAME）;
    spnLecture.setAdapter（适配器）;
 

解决方案

ParseQueryAdapter可能使用SpinnerAdapter下方。

要解决这个问题的一个方法是降低你的targetSdkVersion。 此错误是被报告为21 targetSdkVersion

请在这里看到： https：//开头code.google.com/p/android/issues/detail?id=79011

有一个长期的解决方案是修复适配器，这是不可能的情况下，直到解析团队决定来解决它的实施。

我曾与SpinnerAdapter同样的问题，得到了其使用targetSdkVersion 19.希望它能帮助！

工作没有外围损坏

I am using Parse.com in my application when I use ParseQueryAdapter in fragment to retrieve data and pass to a spinner an error as

java.lang.IllegalArgumentException: Spinner adapter view type count must be 1

and application stops. However if I try ArrayAdapter it works. What could be the problem?

ParseQueryAdapter Code:

ParseQueryAdapter.QueryFactory<ParseObject> spnQuery=
            new ParseQueryAdapter.QueryFactory<ParseObject>() {
                public ParseQuery create() {
                    ParseQuery query = new ParseQuery(tableName);
                    return query;
                }
            };
    ParseQueryAdapter<ParseObject> adapter = new ParseQueryAdapter<ParseObject>(getActivity().getApplicationContext(), spnQuery);
    adapter.setTextKey(columnName);
    spnLecture.setAdapter(adapter);

解决方案

ParseQueryAdapter might be using SpinnerAdapter underneath.

One way to solve this issue is to lower your targetSdkVersion. This error is being reported for targetSdkVersion of 21.

Please see here : https://code.google.com/p/android/issues/detail?id=79011

A long term solution is to fix the implementation of the adapter, which is not possible for your case until Parse team decides to fix it.

I had the same issue with SpinnerAdapter and got it working without peripheral damage using targetSdkVersion 19. Hope it helps!
