我有一个有 2 个旋转器的活动。我用从像这样的 xml 文件中获取的列表填充微调器：

<outil id="1" name="Décompacteur">
    <travail id="1">Travail au sol</travail>
    <travail id="1001">Autre</travail>
</outil>
<outil id="2" name="Cultivateur">
    <travail id="3">Travail au sol</travail>
    <travail id="1002">Autre</travail>
</outil>

在另一个活动中，我可以更改构建列表的文件。

我的问题是：我在一长串工具的末尾选择了一个工具（outil），例如 position = 6。然后我更改了文件，工具列表现在只有 4 个项目。我设置了一个新的适配器：

listNameOutil = getOutilNameList(listOutilObject);
adapterOutil = new ArrayAdapter<String>(this, R.layout.spinners_base, listNameOutil);
adapterOutil.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner_outil.setAdapter(adapterOutil);

但我仍然得到一个错误，我不知道它来自哪里，只要堆栈跟踪中没有“引起”......请注意，我也做了一个spinner_outil.setSelection(positionSaved);. 起初，我试图捕捉这一行的异常，但问题似乎不是这一行。

有什么想法可以解决这个问题吗？

这是堆栈跟踪：

编辑 ：

在开始时，我绑定到我的服务。然后，在 onServiceConnected 中，我向服务询问配置信息：

        try {
            remoteServiceMain.requeteLireConfig();
        } catch (RemoteException e) {
            e.printStackTrace();
        }

然后，仍然在 onServiceConnected 中，我定义了布局：

spinner_outil = (Spinner) findViewById(R.id.spinner_outil_layout);
spinner_outil.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1, int position, long arg3) {
    }
}

然后 onServiceConnected 就完成了。请注意，我在那里得到错误之前的最后一个日志。

编辑：

我之后做setSelection(positionSaved);，spinner_outil.setAdapter(adapterOutil);当我在调用后从服务中得到答案时，我设置了 positionSaved：

    try {
        remoteServiceMain.requeteLireConfig();
    } catch (RemoteException e) {
        e.printStackTrace();
    }

positionSaved由服务发送，服务从配置文件中获取。positionSaved每次用户单击微调器的项目时都会保存。我从服务而不是直接从文件中获取它的原因是我对其他事情使用相同的方法
