Custom adapters:

Package com.neweriweibo.adapter;/** * Adapter * @author engineer-jsp * @date 2014.10.28 * */import java.util.arraylist;import Com.neweriweibo.r;import Com.neweriweibo.model.userweibiinfo;import Com.squareup.picasso.picasso;import Android.content.context;import Android.util.log;import Android.view.layoutinflater;import Android.view.View; Import Android.view.viewgroup;import Android.widget.baseadapter;import Android.widget.imageview;import Android.widget.textview;public class Messageadapter extends Baseadapter {private Context mcontext;p rivate arraylist&lt ; userweibiinfo> mresult;p rivate layoutinflater layoutinflater;public messageadapter (context context, ArrayList< userweibiinfo> result) {Mcontext = context; mresult = result; Layoutinflater = Layoutinflater.from (Mcontext);} @Overridepublic int GetCount () {return mresult.size ();} @Overridepublic Object getItem (int position) {return mresult.get (position);} @Overridepublic long Getitemid (int position) {return position;} @Overridepublic VIew GetView (int position, View Convertview, ViewGroup parent) {Viewholder holder; View view = Convertview, if (view = = null) {holder = new Viewholder (); view = Layoutinflater.inflate (r.layout.message_list_ item, NULL); holder.tvname = (TextView) View.findviewbyid (r.id.m_tv_username); holder.tvmessage = (TextView) View.findviewbyid (r.id.m_tv_message); holder.headimg = (ImageView) View.findviewbyid (R.id.weibo_item_icon); View.settag (holder); }else{holder = (Viewholder) View.gettag ();} LOG.D ("Weibo friend message-username test:", mresult.get (position). GetName ()); Holder.tvName.setText (Mresult.get (position). GetName ()); LOG.D ("Weibo friend message-content test:", mresult.get (position). Getorigtext ()); Holder.tvMessage.setText (Mresult.get (position). Getorigtext ()); LOG.D ("Weibo friend message-avatar address test:", mresult.get (position). GETHEADIMG ()); Picasso.with (View.getcontext (). Getapplicationcontext ()). Load (mresult.get (position). GETHEADIMG ()). into ( HOLDER.HEADIMG); return view;} Static class Viewholder{textview Tvname; TextView tvmessage; ImageView headimg;}}

Viewholder is one of the ListView optimization methods

Send Message interface:

Currently only with text send function, expression package are in the source code has, interested, can continue to develop, the following provide source learning:

OK, things are not many, the key is to master the method
