Android MaoZhuaWeiBo Adapter ListView optimization and sending Weibo, android Weibo sharing

This article mainly tells you about the optimization of the Adapter ListView and the microblog sending. We all know that Android is in some memory-consuming classes, in order to avoid waste of resources as much as possible.

To save unnecessary resource waste, we need to optimize our components and so on.

Custom adapter:

Package com. neweriweibo. adapter;/*** adapter * @ author Engineer-Jsp * @ date 2014.10.28 **/import java. util. arrayList; import com. neweriweibo. r; import com. neweriweibo. model. userweibo iinfo; 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; private ArrayList <userweibo iinfo> mresult; private LayoutInflater layoutinflater; public MessageAdapter (Context context, ArrayList <userweibo iinfo> 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-profile picture 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 methods to optimize ListView.

Message sending interface:

Currently, only the text sending function is provided. Table packages are available in the source code. If you are interested, you can continue development. The following describes how to learn source code:

Address: <a target = _ blank href = "http://download.csdn.net/detail/jspping/8117425" target = "_ blank"> http://download.csdn.net/detail/jspping/8117425 </a> <strong> <span style = "font-size: 14px; color: # ff0000; "> </span> </strong> <pre name =" code "class =" java ">

OK. There are not many things. The key is to master the method.

The android ListView has been optimized by third-party class libraries.

Android-pulltorefresh is a powerful open-source project for pulling and refreshing, and supports pull-down and refreshing of various controls.
Android-pulltorefresh-listview pull-down refresh ListView
DropDownListView pull-down refresh and slide to the bottom to load more ListView
