Android Listview与Checkbox结合实现选择，删除，显示选择结果

 

网上有很多Listview与Checbox结合的例子，大多都存在这样那样的问题，要么选择异常，要么滚动Listview后选择消失，要么删除异常，要么无法正常显示选择结果。

以下为真正无误的，实用的Listview与Checkbox结合实现选择，删除，显示选择结果。

MainActivity.java

package com.example.listviewcheckbox;

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

import com.example.listviewcheckbox.R;

import android.app.Activity;
import android.app.AlertDialog;

import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {
	
	Button show;
	Button select;
	Button deselect;
	ListView lv;
	Context mContext;
	MyListAdapter adapter;

	List selected = new ArrayList();
	private List items;
	
	
    /** Called when the activity is first created. */
    @Override
