这是我的代码，总是先执行httpPostToUpdateMyLocation 然后再执行 httpCreatMyTable(); 和httpGetTableId(); 我的想法是 让 httpCreatMyTable();和httpGetTableId()先执行，得到geoTableID，但是最后还是先执行httpPostToUpdateMyLocation 请问该如何解决！

TelephonyManager telephonyManager = (TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE);
imei = telephonyManager.getDeviceId();
//向服务器查询表格获得表格ID;
httpCreatMyTable(); //创建表格，首次运行
httpGetTableId(); //获得表格
httpPostToUpdateMyLocation(location); //传输数据

因为httpGetTableId调用LocationHttpClient.get是异步的，需要等onSuccess运行完。
你可以在主程序中做一个死循环，去等待一个boolean值，当onsuccess返回，再往下执行httpPostToUpdateMyLocation
