我正在向数据库(SQLite 数据库)添加一个新用户。当我单击按钮创建用户时,我使用的是 doInBackground。当我连接到 WCF Web 服务时,它工作正常。我改用 SQLite 数据库,但是 asyncTask 的 doInBackground 方法没有被执行。所有的更改都是在 AddUser() 方法中进行的。不抛出异常,logcat中也没有什么异常。我在这里做错了什么?

// 点击事件代码:

if(!(username.matches("") && password.matches("")&& firstName.matches("") && lastName.matches("")))
            {
                userNameRequired.setVisibility(View.INVISIBLE);
                passwordRequired.setVisibility(View.INVISIBLE);
                firstNameRequired.setVisibility(View.INVISIBLE);
                lastNameRequired.setVisibility(View.INVISIBLE);
              try
              {
                 new Thread(
                     new Runnable() {
                         @Override
                         public void run() {
                  **This is where it stops and does nothing.**
                             new   createNewUserAsyncTask().execute();  
                         }
                     }
             ).start();

更改您的代码以取出ThreadRunnable

if(!(username.matches("") && password.matches("")&& firstName.matches("") && lastName.matches("")))
        {
            userNameRequired.setVisibility(View.INVISIBLE);
            passwordRequired.setVisibility(View.INVISIBLE);
            firstNameRequired.setVisibility(View.INVISIBLE);
            lastNameRequired.setVisibility(View.INVISIBLE);

              **This is where it stops and does nothing.**
            new   createNewUserAsyncTask().execute();

AsyncTask必须在UI

根据文档,4个线程规则之一(实际上是第一个)是

AsyncTask 类必须在 UI 线程上加载。这是从 JELLY_BEAN 自动完成的。
