這一篇主要給大家說說Adapter ListView最佳化及發送微博，我們都知道Android在一些比較耗記憶體的類裡，為了盡量避免浪費內

存，我們需要對我們的組件之類的進行最佳化，使其節約不必要的資源浪費

自訂配接器：

package com.neweriweibo.adapter;/** * 適配器 * @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 ;private ArrayList<UserWeiBiInfo> mresult ;private 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("微博好友訊息-使用者名稱測試：", mresult.get(position).getName());holder.tvName.setText(mresult.get(position).getName());Log.d("微博好友訊息-內容測試：", mresult.get(position).getOrigtext());holder.tvMessage.setText(mresult.get(position).getOrigtext());Log.d("微博好友訊息-頭像地址測試：", 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 就是ListView最佳化辦法之一，屢試不爽

發送訊息介面：

目前只帶文本發送功能，表情包都在原始碼裡有，有興趣的，可以繼續開發，下面提供源碼學習：

OK，東西又不是很多，關鍵是掌握方法
