用jsp做婚纱网站的流程网站优化排名软件网站
我正在使用的应用程序具有登录/注册,该登录/注册连接到mysql数据库.起初,我在UI线程上运行了所有程序,后来发现由于在Android的UI线程上运行较长的代码而无法正常工作.我试图编辑我的代码以在添加的新线程上运行长任务.
.现在我的应用程序注册了我在mysql中看到的结果,但是由于这个错误,我的应用程序一直关闭
android.view.ViewRootImpl$CalledFromWrongThreadException:
Only the original thread that created a view hierarchy can touch its views.
该错误是可以理解的,但我不知道如何将一个或多个View运行回UI线程.
我已经对runOnuithread进行了一些研究,但是我不知道将其放置在代码中的位置,或者天气我将之前添加的新线程放在错误的位置开始,请
谁能帮我解决这个问题
这是代码片段
