Question

我有一个微调器，我正在动态加载微调器和消息我这样做如下

protected List<Message> messages = null;
ArrayAdapter <Message> arrayadapter = new ArrayAdapter<Message>( activity,android.R.layout.simple_spinner_item,messages);               

                       spinner1.setAdapter(arrayadapter);

我收到如下信息

public List<Message> getMessages(String type) throws Exception{
    HttpClient client = new HttpClient();
    GetMethod get = null;
    Message message = null;
    List<Message> messages = new ArrayList<Message>();
    try {
        get = new GetMethod("http://" + Constants.CLOUD_SERVER_URL + Constants.getMessages + "/"+type);
        int statusCode = client.executeMethod(get);
        if(statusCode == 200){
            Log.d(TAG, "Successfully posted the comments");
            Utils utils = new Utils();
            Document doc = utils.formatInputStream(get.getResponseBodyAsStream());
            NodeList listMessages = doc.getElementsByTagName("message");
            int totalMessage = listMessages.getLength();
            for (int s = 0; s < totalMessage; s++) {
                Node messageNode = listMessages.item(s);
                if (messageNode.getNodeType() == Node.ELEMENT_NODE) {
                    Element messageElement = (Element) messageNode;
                    message = new Message();
                    message.setId(utils.getTagValue(messageElement, "id"));
                    message.setMessage(utils.getTagValue(messageElement, "question"));
                    messages.add(message);

                    Log.d(TAG, "Id - " + message.getId() + " Message - " + message.getMessage());
                }
            }
        }else{
            Log.d(TAG, "Either server has problem or not reachable at this time");
            throw new Exception("Server Issue Status code return by server is " + statusCode);
        }
        Log.d(TAG, "recommend ----------> Step 15");
        Log.d(TAG, "recommend ----------> Step 20");
    }finally{
        get.releaseConnection();
        get = null;
    }
    return messages;
}

我的问题是我在微调器中获取消息的id而不是消息文本如何将该消息转换为字符串并将其传递给适配器或最后我在旋转器中得到文本的任何其他方式。

一种方法是覆盖toString()类的Message方法并返回消息值，如下所示：

@Override
public String toString() {
    return message; //where message is member variable holding message text
}

Android：将字符串传递给ArrayAdapter
