Question

我需要帮助。我得到“getText（）。toString（）”的错误，它说：“getTEXT方法应该从UI线程调用......”这是什么意思呢？当提交数据时，数据不会保存在数据库中。有人可以帮我请我的时间不多了已经？：'（如果有需要什么，让我知道

Answer 1

不能使用的UI元素getText()（你的EditText-S）作为AsyncTask.doInBackground()运行中单独的线程并且无法访问UI元素。 你实际上是在做正确的new SubmitData().execute(Name, Age, Gender, Email, Phone, IncidentType, Description);，并从里面doInBackground()
