Android中ListView结合CheckBox判断选中项

本文主要实现在自定义的ListView布局中加入CheckBox控件，通过判断用户是否选中CheckBox来对ListView的选中项进行相应的操作。通过一个Demo来展示该功能，选中ListView中的某一项，然后点击Button按钮来显示选中了哪些项。

[1] 程序结构图如下：

其中Person.java是实体类，MainActivity.java是Activity组件类。listitem.xml是自定义的列表每项布局文件。

[2] listitem.xml布局文件源码如下：

[3] main.xml布局文件源码如下：

[4] Person.java实体类源码如下：

package com.andyidea.bean; public class Person { private String name; private String address; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } }
[5] MainActivity.java类源码如下：

package com.andyidea.listview; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import com.andyidea.bean.Person; import android.app.Activity; import android.app.AlertDialog; import android.content.Context; import android.os.Bundle; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.Button; import android.widget.CheckBox; import android.widget.ListView; import android.widget.TextView; public class MainActivity extends Activity { Button show; ListView lv; List persons = new ArrayList(); Context mContext; MyListAdapter adapter; List listItemID = new ArrayList(); /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mContext = getApplicationContext(); show = (Button)findViewById(R.id.show); lv = (ListView)findViewById(R.id.lvperson); initPersonData(); adapter = new MyListAdapter(persons); lv.setAdapter(adapter); show.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { listItemID.clear(); for(int i=0;i mChecked; List listPerson; HashMap map = new HashMap(); public MyListAdapter(List list){ listPerson = new ArrayList(); listPerson = list; mChecked = new ArrayList(); for(int i=0;i
