利用ListView批量删除item

利用CheckBox选中一个或多个item，最后批量删除它们。 

程序运行效果图如下：

 

package com.test.adapter;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.app.ListActivity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.BaseAdapter;
import android.widget.CheckBox;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;

import com.test.adapter.ArrayAdapterActivity.ListVIewAdapter.ViewHolder;
