ListView嵌套CheckBox （解决滑动时重复选择的问题）
adapter中做处理：
package com.chenglang.adapter;
import java.util.ArrayList;
import java.util.HashMap;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.CheckBox;
import android.widget.TextView;
public class Mytxtl_list_adapter extends BaseAdapter {
