服务IntentService以及传递服务的处理结果

@EActivity(R.layout.input_club_name)
public class JoinActivity extends BaseActivity{
    @ViewsById({R.id.et_input_room_roomName,
                R.id.et_input_room_name})
    ArrayList<EditText> etlist = new ArrayList<EditText>();
    
    @Click(R.id.btn_input_club_name_submit)
    public void join(){
        //显示进度条
        ProgressBarUtil.show(this, "正在连接服务器，请稍后...");
        
        String roomName = etlist.get(0).getText().toString();
        String Name = etlist.get(1).getText().toString();
        
        //启动IntentService
        Intent intent = new Intent(this,ClubBiz.class); 
        intent.putExtra("roomName", roomName);
        intent.putExtra("Name", Name);
        
        //如何将Service的结果返回给activity:发广播，PendingIntent
        int requestCode = 100;
        Intent data = new Intent();
        int flags = 0;
        PendingIntent pendingIntent =this.createPendingResult(requestCode, data, flags);
        
        //将pendingIntent放到启动service的intent中。
        intent.putExtra("pendingIntent", pendingIntent);
        startService(intent);//1.注册服务：<service android:name=".biz.ClubBiz" > 启动服务并传递登陆的房间和房间名
    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {//4.根据pengdIntent传递的结果做进一步的处理。
        super.onActivityResult(requestCode, resultCode, data);
        try{
            if(requestCode==100 && resultCode ==200){
                int status = data.getIntExtra(Constants.KEY_STATUS, -1);
                if(status==Constants.STATE_OK){
                    ProgressBarUtil.close();
                    Tools.showInfo(this, "加入成功！");
                    startActivity(new Intent(this,ChatActivity_.class));
                }
                if(status==Constants.STATE_FAILURE){
                    ProgressBarUtil.close();
                    Tools.showInfo(this, "加入俱乐部失败！");
                }
            }
        }catch (Exception e) {
            ExceptionUtil.handlerException(e);
        }
    }
}

    //    public ClubBiz(String name) {
