Android的：如何获得使用ArrayAdapter微调项的ID [英] Android: How to get id of the spinner item using ArrayAdapter

问题描述

我的微调载有一些信息，每条都有伊茨自己的ID，

 公共类信息{
    私人字符串ID;
    私人字符串信息;
    公共字符串的getId（）{
        返回ID;
    }
    公共无效SETID（字符串ID）{
        this.id = ID;
    }
    公共字符串的getMessage（）{
        返回消息;
    }
    公共无效setMessage（字符串消息）{
        this.message =消息;
    }

     @覆盖
     公共字符串的toString（）{
         返回消息;
     }
}
 

我通过这个的消息来Arrayadapter，

 保护名单，其中;消息＆GT;消息=无效;
    ArrayAdapter＆LT;消息＆GT; arrayadapter =新的ArrayAdapter＆LT;消息＆GT;（活动，android.R.layout.simple_spinner_item，消息）;
                        arrayadapter.setDropDownViewResource（R.layout.textview）;
 spinner1.setAdapter（arrayadapter）;
 

现在如何，我可以得到该特定消息的ID选择？ 我能做到这一点与arrayadapter。任何帮助pciated AP $ P $

解决方案

  spinner1.setOnItemSelectedListener（新AdapterView.OnItemSelectedListener（）{
        公共无效onItemSelected（适配器视图＆LT;＆GT;母公司视图中查看，
                INT POS，长I​​D）{
            消息mSelected =（消息）parent.getItemAtPosition（POS）;
            Log.i（ID：，mSelected.getId（））;

        }

        @覆盖
        公共无效onNothingSelected（适配器视图＆LT;＆GT;为arg0）{
            // TODO自动生成方法存根
            Log.i（消息，没有选择）;

        }


    }）;
 

My spinner is loaded with some messages ,each message has itz own id,

public class Message {
    private String id;
    private String message;
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getMessage() {
        return message;
    }
    public void setMessage(String message) {
        this.message = message;
    }

     @Override
     public String toString() {          
         return  message;
     }
}

I am passing this message to Arrayadapter,

   protected List<Message> messages = null;
    ArrayAdapter <Message> arrayadapter = new ArrayAdapter<Message>( activity,android.R.layout.simple_spinner_item,messages);               
                        arrayadapter.setDropDownViewResource(R.layout.textview);
 spinner1.setAdapter(arrayadapter); 

Now how can i get the id of that particular message selected? can i do it with arrayadapter .Any help is appreciated

解决方案

spinner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        public void onItemSelected(AdapterView<?> parent, View view,
                int pos, long id) {
            Message mSelected = (Message) parent.getItemAtPosition(pos);
            Log.i("Id:", mSelected.getId());

        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub
            Log.i("Message", "Nothing is selected");

        }


    });
