1.基础的适配器

2.简单的适配器

3.啥也别说了上代码

package com.zgy.listviewdemo;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.widget.AbsListView;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.ArrayAdapter;import android.widget.ListView;        /*      * XML文件就是定义个listview与之对应      *       * */public class MainActivity extends Activity {private static final String[] str= new String[]{"first","second","third","fourth","fifth"};//定义一个数组来显示数量private ListView lView;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);     lView =(ListView)findViewById(R.id.listview_id);          //为list适配绑定 这种为最常见    // lView.setAdapter(new ArrayAdapter<String>(this,       //      android.R.layout.simple_list_item_1, str));//为list适配绑定 为单项    //  lView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_checked,str));    //  lView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);    //为list适配绑定 为多选     lView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_checked,str));     lView.setChoiceMode(AbsListView.CHOICE_MODE_MULTIPLE);          //list添加监听     lView.setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> parent, View arg1, int arg2,long arg3) {// TODO Auto-generated method stubsetTitle("你点击了第"+arg2+"行");}     });}}
