Answer 1

使用 Handlers 、 UI-threads 或 AsyncTask （postexecute） 来调用 notifydatasetchanged(); 。您正在后台线程中执行此操作...

Answer 2

在下面调用这个，把它放在一个线程中

             runOnUiThread(new Runnable(){
                 @Override
                 public void run() {
                    // call it here
                 }  
             }
