防携程筛选，listview和checkbox结合使用

 最近一直做一款旅游的APP，有一个刷选的功能，一看很简单，但是最后搞了很久，日了狗。先不说放图

！！！！
其实呢原理很简单，就是两个listview 的合并还有listview 和CheckBox的混合使用！！！！！
首先呢原理很简单就是有一个PopupWindow 里面有两个listView，左边一个，右边一个（废话），
点击左边的listview。相应弹出相应右边的listview,然后右边的listview里面还有CheckBox，然后就是防止CheckBox的错乱，点击取消，确定，清除，相应的操作。
首先主布局：

然后就是PopupWindow的布局，都很简单，哈哈哈！

然后就是两个listview 的两个Adapter:
第一个FirstClassAdapter很简单直接上代码：

public class FirstClassAdapter extends BaseAdapter {
private Context context;
private List list;

public FirstClassAdapter(Context context, List list) {
    this.context = context;
    this.list = list;
}

@Override
public int getCount() {
    return list == null ? 0 : list.size();
}

@Override
public Object getItem(int i) {
    return null;
}

@Override
public long getItemId(int i) {
    return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup viewGroup) {
    ViewHolder holder;
    if (convertView == null) {
        convertView = LayoutInflater.from(context).inflate(
                R.layout.left_listview_item, null);
        holder = new ViewHolder();

        holder.nameTV = (TextView) convertView
                .findViewById(R.id.left_item_name);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    if (position == selectedPosition) {
        convertView.setBackgroundResource(R.color.popup_right_bg);
    } else {
        convertView.setBackgroundResource(R.drawable.selector_left_normal);
    }

    holder.nameTV.setText(list.get(position).getName());

    return convertView;
}

private int selectedPosition = 0;

public void setSelectedPosition(int selectedPosition) {
    this.selectedPosition = selectedPosition;
}

public int getSelectedPosition() {
    return selectedPosition;
}

private class ViewHolder {
    TextView nameTV;
}

}

左边listview的布局：

右边的SecondClassAdapter：
public class SecondClassAdapter extends BaseAdapter {
private Context context;
private List list;
private boolean isShow = false;
ArrayList dayscheckTrue = new ArrayList();
ArrayList dayscheckFalse = new ArrayList();
ArrayList timecheckTrue = new ArrayList();
ArrayList timecheckFalse = new ArrayList();
ArrayList pricecheckTrue = new ArrayList();
ArrayList pricecheckFalse = new ArrayList();

public SecondClassAdapter(Context context, List list
        ) {
    this.context = context;
    this.list = list;


}

public boolean isShow() {
    return isShow;
}

public void setShow(boolean isShow) {
    this.isShow = isShow;
}

@Override
public int getCount() {
    return list == null ? 0 : list.size();
}

@Override
public Object getItem(int position) {
    return null;
}

@Override
public long getItemId(int position) {
    return 0;
}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    ViewHolder holder;

    if (convertView == null) {
        holder = new ViewHolder();
        convertView = LayoutInflater.from(context).inflate(
                R.layout.right_listview_item, null);
        holder.nameTV = (TextView) convertView
                .findViewById(R.id.right_item_name);
        holder.cb = (CheckBox) convertView.findViewById(R.id.item_cb);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }
    final SecondClassItem classItem = list.get(position);

    holder.nameTV.setText(list.get(position).getName());

    holder.cb.setChecked(classItem.isChecked());
    return convertView;
}

private class ViewHolder {
    TextView nameTV;
    CheckBox cb;
} 

然后就是两个Bean类：
public class FirstClassItem {
private int id;
private String name;
private List secondList;

public FirstClassItem() {

}

public FirstClassItem(int id, String name, List secondList) {
    this.id = id;
    this.name = name;
    this.secondList = secondList;
}

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public List getSecondList() {
    return secondList;
}

public void setSecondList(List secondList) {
    this.secondList = secondList;
}

@Override
public String toString() {
    return "FirstClassItem{" + "id=" + id + ", name='" + name + '\''
            + ", secondList=" + secondList + '}';
}

第二个，因为第二个有CheckBox 所以我写一个 isChecked 字段，其实listview和checkbox 在一起有很多种解决方式，有兴趣可以看我另一篇博客，介绍一下我用过的方法。

public class SecondClassItem {
private int id;
private String name;
private boolean isChecked;
private int ids;

public int getIds() {
    return ids;
}

public void setIds(int ids) {
    this.ids = ids;
}

public SecondClassItem() {

}

public SecondClassItem(int id, String name, boolean isChecked, int ids) {
    super();
    this.id = id;
    this.name = name;
    this.isChecked = isChecked;
    this.ids = ids;
}

public boolean isChecked() {
    return isChecked;
}

public void setChecked(boolean isChecked) {
    this.isChecked = isChecked;
}

public boolean getChecked(boolean isChecked) {
    return isChecked;
}

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

@Override
public String toString() {
    return "SecondClassItem{" + "id=" + id + ", name='" + name + '\'' + '}';
}

关键代码就是MainActivity中了，备注很详细，有用的朋友只需改变极少代码就可以使用很简单，上代码：
public class MainActivity extends Activity implements OnClickListener {

/** 左侧一级分类的数据 */
private List firstList;
/** 右侧二级分类的数据 */
private List secondList;
// 二级数据
List list2;
// 保存的数据
private ArrayList dayMap = new ArrayList();
private ArrayList timeMap = new ArrayList();
private ArrayList priceMap = new ArrayList();
// 旅游的列表
private boolean isfrist = true;
private TextView textviewClick;
private PopupWindow popupWindow;
private ListView leftLV, rightLV;

private TextView textview_confirm;
private SecondClassAdapter secondAdapter;
private FirstClassAdapter firstAdapter;

private String val = "";
private String val2 = "";
private String val3 = "";

// 右边显示的数据
private List days = new ArrayList();
private List date = new ArrayList();
private List prices = new ArrayList();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    initView();

}

private void initView() {
    textviewClick = (TextView) findViewById(R.id.textviewClick);

    textviewClick.setOnClickListener(this);

}

// 初始化数据，你只要改这里就可以
private void requestList() {
    firstList = new ArrayList();

    days.add("2");

    date.add("2016-3-17");
    date.add("2016-3-18");
    date.add("2016-3-19");

    prices.add("1元");
    prices.add("2元");
    prices.add("3元");
    prices.add("4元");
    // 1
    ArrayList secondList1 = new ArrayList();
    secondList1.add(new SecondClassItem(0, "不限", false, 0));
    for (int i = 0; i < days.size(); i++) {
        secondList1
                .add(new SecondClassItem(i, days.get(i) + "天", false, 0));
    }

    firstList.add(new FirstClassItem(1, "行程天数", secondList1));
    // 2
    ArrayList secondList2 = new ArrayList();
    secondList2.add(new SecondClassItem(0, "不限", false, 0));
    for (int i = 0; i < date.size(); i++) {
        secondList2.add(new SecondClassItem(i, date.get(i), false, 0));
    }
    firstList.add(new FirstClassItem(2, "出发时间", secondList2));
    // 3
    ArrayList secondList3 = new ArrayList();
    secondList3.add(new SecondClassItem(0, "不限", false, 0));

    for (int i = 0; i < prices.size(); i++) {
        secondList3.add(new SecondClassItem(i, prices.get(i), false, 0));
    }
    firstList.add(new FirstClassItem(3, "价格区间", secondList3));

        }
        // 这里就是你点击后的逻辑
        Toast.makeText(MainActivity.this,
                "选择的数据天数" + val + "----日期" + val2 + "-----价格区间" + val3,
                Toast.LENGTH_LONG).show();

        popupWindow.dismiss();
        break;
    default:
        break;
    }

}

}

然后清除筛选和取消类似，简单吧。。。。。。。。。。。。。。
