我的代码提供了正确的响应并正确设置了事务ID。但是在屏幕上,我第一次提交时ID丢失,当我再次返回并再次提交时,屏幕上的ID就是第一次交易的ID。
在首次提交上,会显示:
MOBILE NUMBER: 9129992929
OPERATOR: AIRTEL
AMOUNT: 344
TRANSACTION ID:
在第二次提交上,会显示:
MOBILE NUMBER: 9129992929
OPERATOR: AIRTEL
AMOUNT: 344
TRANSACTION ID: NUFEC37WD537K5K2P9WX
我希望在第一次提交时看到第二个屏幕。
对第一次提交的回复:
D/TID IS: ====>NUFEC37WD537K5K2P9WX D/UID IS:
====>27W3NDW71XRUR83S7RN3 D/Response-------: ------>{"tid":"NUFEC37WD537K5K2P9WX","uid":"27W3NDW71XRUR83S7RN3","status":"ok"}
对第二次提交的回复:
D/TID IS: ====>18R6YXM82345655ZL3E2 D/UID IS:
====>27W3NDW71XRUR83S7RN3 D/Response-------: ------>{"tid":"18R6YXM82345655ZL3E2","uid":"27W3NDW71XRUR83S7RN3","status":"ok"}

这是设置ID的地方。
MyApplication _Rechargedetail =(MyApplication)getApplicationContext();
confirm_tId =(TextView)findViewById(R.id._Tid);
String _tid =_Rechargedetail.getTId_name();
confirm_tId.setText(_tid);
答案 0 :(得分:0)
您的代码行应在完成网络操作并执行onPostExecute()后执行;您的AsyncTask。
confirm_tId.setText(_tid);
