handler和thread解析数据，以及将网络请求写到一个类里面进行数据解析

网络请求类：

package com.example.liangminghuitwo;

import java.io.IOException;

import org.apache.http.HttpClientConnection;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.params.BasicHttpParams;
import org.apache.http.params.HttpConnectionParams;
import org.apache.http.params.HttpParams;
import org.apache.http.util.EntityUtils;

public class Myutils {
    public static String getData(String url){
        String result=null;
        HttpGet get=new HttpGet(url);
        //设置参数
        HttpParams params=new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(params, 5000);
        //创建HTTPClinent
        HttpClient client=new DefaultHttpClient(params);
        try {
            HttpResponse httpResponse=client.execute(get);
            if(httpResponse.getStatusLine().getStatusCode()==200){
                HttpEntity httpEntity=httpResponse.getEntity();
                result=EntityUtils.toString(httpEntity, "utf-8");
            }
        
        
        
        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
        
        
        return result;
    }
}

MainActivity.class:

package com.example.liangminghuitwo;

import java.util.ArrayList;
import java.util.List;

import com.example.adapter.Mybase;
import com.example.vo.Data;
import com.example.vo.Demo;
import com.google.gson.Gson;

import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.app.Activity;
import android.database.sqlite.SQLiteDatabase;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.TextView;

public class MainActivity extends Activity {
    private ListView list_view;
    private TextView text_find;
    private EditText edit_find;
    String urls="http://93.gov.cn/93app/get_search.do?key=";
    private List<Demo> data=new ArrayList<Demo>();
    
    private String st;
    Handler han=new Handler(){
        @Override
        public void handleMessage(Message msg) {
            // TODO Auto-generated method stub
            super.handleMessage(msg);
            
            String rs=(String) msg.obj;
            Gson g=new Gson();
            Data de=g.fromJson(rs, Data.class);
            data=de.getData();
            Mybase base=new Mybase(data, getApplicationContext());
            list_view.setAdapter(base);
            
        }
        
    };
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        list_view=(ListView) findViewById(R.id.list_view);
        text_find=(TextView) findViewById(R.id.text_find);
        edit_find=(EditText) findViewById(R.id.edit_find);
        st=text_find.getText().toString().trim();
        text_find.setOnClickListener(new OnClickListener() {
            
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                new Thread(){
                    public void run() {
                        final String name=edit_find.getText().toString().trim();

                        String str=Myutils.getData(urls+name);
                        han.sendMessage(han.obtainMessage(1,str));
                        
                        
                    };
                    
                }.start();
            }
        });
        
        
        
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

}

以及添加适配器：Mybase.class

package com.example.adapter;

import java.util.List;

import com.example.liangminghuitwo.R;
import com.example.vo.Demo;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

public class Mybase extends BaseAdapter{
        private List<Demo> data;
        private Context context;
        
    public Mybase(List<Demo> data, Context context) {
            super();
            this.data = data;
            this.context = context;
        }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return data.size();
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return data.get(position);
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        Viehoder vh;
        if(convertView==null){
            vh=new Viehoder();
            convertView=LayoutInflater.from(context).inflate(R.layout.item,null);
            vh.text_time=(TextView) convertView.findViewById(R.id.text_time);
            vh.text_two=(TextView) convertView.findViewById(R.id.text_two);
            vh.text_title=(TextView) convertView.findViewById(R.id.text_title);
            convertView.setTag(vh);
        }else{
            vh=(Viehoder) convertView.getTag();
        }
        vh.text_time.setText(data.get(position).getSHOWTIME());
        vh.text_title.setText(data.get(position).getTITLE());
        vh.text_two.setText(data.get(position).getFROMNAME());
        return convertView;
    }
class Viehoder{
    TextView text_title,text_two,text_time;
    
}
}

效果图：
