/ / Instantiate a handler

Handler handler = new Handler ()
{
/ / After receiving the message processing

public void handleMessage (Message msg)

{
switch (msg.what)

{

case 1:
/ / Log.i ("--------------", "0000000000000000");
Intent intent = new Intent (CommentsActivity.this, CommentsActivity.class);
intent.putExtra ("nid", mNid);
startActivity (intent);
/ / CommentsAdapter.notifyDataSetChanged ();
/ / CommentsList.invalidate (); / / refresh interface
break;

}

super.handleMessage (msg);

}

};

If it can jump again. I do not know there is no better way to do

The written description of the method call Adapter for notifyDataSetChanged () method is generally the main UI thread will work in it, empathy invalidate () method is the same, still need to borrow Handler in the main UI thread work . For insurance purposes, I usually practice together with the project is a combination of absolute and effective :)

commentsList.setAdapter (commentsAdapter) ;/ / Reset commentsAdapter
updated to listviewcommentsAdapter.notifyDataSetChanged (); / / update the display

There are two way of life, one is required to take, one is the way you want to go. Must only take a good way to go, want to go to go to go its own way.
