先是Bean中的

package?com.tong;

public?class?Bean?{
	private?String?view_title;
????private?String?view_content;
????private??String?view_time;
????private?String?view_phone;
????public?Bean()?{
		
	}
	public?Bean(String?view_title,?String?view_content,?String?view_time,
			String?view_phone)?{
		super();
		this.view_title?=?view_title;
		this.view_content?=?view_content;
		this.view_time?=?view_time;
		this.view_phone?=?view_phone;
	}
	
	public?String?getView_title()?{
		return?view_title;
	}
	public?void?setView_title(String?view_title)?{
		this.view_title?=?view_title;
	}
	public?String?getView_content()?{
		return?view_content;
	}
	public?void?setView_content(String?view_content)?{
		this.view_content?=?view_content;
	}
	public?String?getView_time()?{
		return?view_time;
	}
	public?void?setView_time(String?view_time)?{
		this.view_time?=?view_time;
	}
	public?String?getView_phone()?{
		return?view_phone;
	}
	public?void?setView_phone(String?view_phone)?{
		this.view_phone?=?view_phone;
	}
}

2.MainActivity中的’

package?com.example.baseadapter;
import?java.util.ArrayList;
import?java.util.List;
import?android.app.Activity;
import?android.os.Bundle;
import?android.widget.ListView;
import?com.tong.Bean;
	public?class?MainActivity?extends?Activity?{
	????private?ListView?mlists;
	????private?List<Bean>mdatas;
	????private??MyAdapter?myAdapter;
	????@Override
	????protected?void?onCreate(Bundle?savedInstanceState)?{
	????????super.onCreate(savedInstanceState);
	????????setContentView(R.layout.activity_main);
	????????mlists=(ListView)findViewById(R.id.listview);
	????????mlists.setAdapter(myAdapter);
	????????initData();
	????????}

	????private?void?initData()?{
	//在該方法中初始化定義在Bean中的數(shù)據(jù),先初始化List<Bean>中的mDatas
	????????mdatas=new?ArrayList<Bean>();
	????????Bean?bean=new?Bean("Android的使用技巧1","Android打造萬能適配器來打造ListView和GridView",
	????????????????"2016-08-27","10086");
	????????mdatas.add(bean);
	????????//用這兩行代碼加載數(shù)據(jù)，后面的bean不用重復(fù)定義
	?????????bean=new?Bean("Android的使用技巧2","Android打造萬能適配器來打造ListView和GridView",
	????????????????"2016-08-27","10086");
	????????mdatas.add(bean);
	?????????bean=new?Bean("Android的使用技巧3","Android打造萬能適配器來打造ListView和GridView",
	????????????????"2016-08-27","10086");
	????????mdatas.add(bean);
	?????????bean=new?Bean("Android的使用技巧4","Android打造萬能適配器來打造ListView和GridView",
	????????????????"2016-08-27","10086");
	????????mdatas.add(bean);
	//初始化這些數(shù)據(jù)之后就需要新建一個適配器MyAdapter
	????????//數(shù)據(jù)傳入后，加載適配器，需要傳入兩個參數(shù)，第一個Activity，第二個是mdatas
	????????myAdapter=new?MyAdapter(this,mdatas);//然后在listview中加載該適配器

	????}
	}

3.MyAdapter中的

package?com.example.baseadapter;

import?java.util.List;

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

import?com.tong.Bean;

public?class?MyAdapter?extends?BaseAdapter{
	private?LayoutInflater?inflater;
????private?List<Bean>?mdatas;
????//聲明這個構(gòu)造方法Context用于加載我們的布局文件
????public?MyAdapter(Context?context,?List<Bean>datas){
????????inflater=LayoutInflater.from(context);
????????mdatas=datas;//獲取到的數(shù)據(jù)集用于編寫下面的屬性
????}
????@Override
????public?int?getCount()?{
????????return?mdatas.size();
????}

????@Override
????public?Object?getItem(int?i)?{
????????return?mdatas.get(i);
????}

????@Override
????public?long?getItemId(int?i)?{
????????return?i;
????}

????@Override
????public?View?getView(int?i,?View?view,?ViewGroup?viewGroup)?{
????????ViewHolder?viewHolder=null;//聲明一個ViewHolder
????????if(view==null){
????????????//判斷是否已經(jīng)加載，加載定義的布局
????????????view=inflater.inflate(R.layout.listview_data,viewGroup,false);

????????????viewHolder=new?ViewHolder();

????????????viewHolder.mtitle=?(TextView)?view.findViewById(R.id.textview1);
????????????viewHolder.mcontent=?(TextView)?view.findViewById(R.id.textview2);
????????????viewHolder.mtime=?(TextView)?view.findViewById(R.id.textview3);
????????????viewHolder.mphone=?(TextView)?view.findViewById(R.id.textview4);
?????????????view.setTag(viewHolder);
????????}else?{
????????????viewHolder=?(ViewHolder)?view.getTag();

????????}
????????Bean?bean=mdatas.get(i);//定義Bean用來獲取當(dāng)前顯示的數(shù)據(jù)
????????viewHolder.mtitle.setText(bean.getView_title());
????????viewHolder.mcontent.setText(bean.getView_content());
????????viewHolder.mtime.setText(bean.getView_time());
????????viewHolder.mphone.setText(bean.getView_phone());
????????return?view;
????????//這步完成之后去MainActivity.java文件中加載MyAdapter，先新建一個MyAdapter型的變量
????}
????//定義一個ViewHolder類用于存放數(shù)據(jù)類型及性能優(yōu)化
????private?class?ViewHolder{
????????TextView?mtitle;
????????TextView?mcontent;
????????TextView?mtime;
????????TextView?mphone;

????}
}
