Achieve key

On the basis of the previous code, you simply add a certain modification to the Onbindviewholder (viewholder holder, int position) function, as follows:

@Override public
 void Onbindviewholder (viewholder holder, int position) {
  //Set up Viewholder to associate with the data
  LOG.D ("Xjj", getitemviewtype (position) + "");
  If Footview exists, and the current position ViewType is Foot_type if
  (Isfootview && (getitemviewtype (position) = Foot_type)) {
   Holder.tvFootView.setText (footviewtext);
   Refresh too fast so use hanlder delay two seconds
   Handler Handler = new Handler ();
   Handler.postdelayed (New Runnable () {
    @Override public
    void Run () {
     max_count = 5;
     Notifydatasetchanged ();
    }

  else {
   Holder.tvViewHolder.setText (mdata.get (position) + position);
  }
 

In the function, first let the item display "in Load ..." ", then use handler, delay two seconds to refresh, the logical content is mainly two, one is to display the maximum capacity increase 5, the second is to refresh the content of adapter.

Expand extension

The author here in order to make readers easy to understand, the use of a lot of places is more coarse, the reader is really used when it will not be so simple, here are listed several points for the reader to learn by themselves:
1, Footview is generally not just a textview, the UI has a certain pursuit of the reader needs to add at least one ProgressBar.
2, adapter content will not be directly used in the list, need to get from the network, and so refresh the content of the adapter generally need to use the thread, rather than a simple handler here can be.
