    java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. Make sure your adapter calls notifyDataSetChanged() when its content changes.

把UR notifySetDataChanged在uithread：

runOnUiThread(new Runnable() { 
       @Override 
       public void run() { 
        adapter. notifysetdatachanged(); 
       } 
      });
