PopupWindow仿淘宝排序选择，多个切换

本人写这些主要是自己记不住所以把一些可能以后会用到的控件或者是功能写上来，写的不好大家不要见怪。


点击旅游类型或者是天数的时候会进行PopupWindow里面的数据切换，不会关闭PopupWindow，再次点击的时会关闭PopupWindow，点击外部区域或者是选择内容之后都会关闭，
下面是主要代码main里面的代码

public class MainActivity extends Activity implements OnClickListener,
        OnTraveLineClick {

    private LinearLayout ll_city;// 定位
    private LinearLayout ll_day;// 天数
    private LinearLayout ll_type;// 类型

    private TextView city_type;// 类型
    private TextView city_day;// 天数

    private View allView;

    private TravelLineAllPopupView popupWindow;

    private List dayList;
    private List typeList;

    /** 类型 */
    private String themeCode = "";
    /** 设置默认天数：全部 */
    private int travelDays = -1;

    /** 哪一个控件show出来的PopupWindow */
    private int isViewClick = -1;
    /** PopupWindow是否显示 1：显示，2：未显示 */
    private int isViewVisibility = 2;

    @Override
    protected void onCreate(Bundle arg0) {
        super.onCreate(arg0);
        setContentView(R.layout.activity_main);
        findViews();
        initViews();
        // 添加天数
        addDayList();
        // 添加主题类型
        addTypeList();

    }

    protected void findViews() {
        ll_city = (LinearLayout) findViewById(R.id.ll_city);
        ll_day = (LinearLayout) findViewById(R.id.ll_day);
        ll_type = (LinearLayout) findViewById(R.id.ll_type);
        city_day = (TextView) findViewById(R.id.city_day);
        city_type = (TextView) findViewById(R.id.city_type);
        allView = (View) findViewById(R.id.allView);

    }

    protected void initViews() {
        ll_city.setOnClickListener(this);
        ll_day.setOnClickListener(this);
        ll_type.setOnClickListener(this);

        popupWindow = new TravelLineAllPopupView(this);

    }

这里是PopupWindow代码

public class TravelLineAllPopupView extends PopupWindow {

    private View mView;
    // ListView展示所需要的适配器
    private TravelLinePopupAdapter adapter;

            @Override
            public void onItemClick(AdapterView parent, View view,

    }

    public interface OnTraveLineClick {
        public void onTraveLineClick(int position, int type);
    }

}

这里是PopupWindow布局代码

    "match_parent"
        android:layout_height="match_parent"
        android:scrollbars="none" >

        "match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >

            <com.example.popupwindowdemo.ListViewExt
                android:id="@+id/mListView"
                android:layout_width="match_parent"
                android:layout_height="0dp"
                android:layout_weight="1"
                android:divider="@null"
                android:listSelector="@null"
                android:scrollbars="none" >
            com.example.popupwindowdemo.ListViewExt>
        
    

这里是ListView控件的代码

/**
 * listView内嵌套ScrollView显示不全

public class ListViewExt extends ListView {

    public ListViewExt(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

    public ListViewExt(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }



    public ListViewExt(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }

    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // 根据模式计算每个child的高度和宽度
        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
                MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
    }

}

下面是adapter适配器的代码

public class TravelLinePopupAdapter extends BaseAdapter {

    private Context context;
    private LayoutInflater mInflater;
    // 将两个list类型换成自己的
    private List list;
    private List typeList;
    private int type;

    public TravelLinePopupAdapter(Context context) {
        this.context = context;

        mInflater = LayoutInflater.from(context);
    }

    public void setList(List list, int type) {
        this.list = list;
        this.type = type;
    }

    public void setTypeList(List list, int type) {
        this.typeList = list;
        this.type = type;
    }

    @Override
    public int getCount() {
        if (type == 1) {
            if (list != null) {
                return list.size();
            } else {
                return 0;
            }
        } else {
            if (typeList != null) {
                return typeList.size();
            } else {
                return 0;
            }

        }
    }

    @Override
    public Object getItem(int position) {
        return list.get(position);
    }

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        if (convertView == null) {
            convertView = mInflater.inflate(R.layout.travel_line_popup_item,
                    null);
            holder = new ViewHolder();
            holder.day = (TextView) convertView.findViewById(R.id.day);
            holder.type = (TextView) convertView.findViewById(R.id.type);

            convertView.setTag(holder);

        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        if (type == 1) {
            holder.day.setVisibility(View.VISIBLE);
            holder.type.setVisibility(View.GONE);
            if (list.get(position) == -1) {
                holder.day.setText("全部");
            } else {
                holder.day.setText(list.get(position) + "天");
            }
        } else if (type == 2) {
            holder.day.setVisibility(View.GONE);
            holder.type.setVisibility(View.VISIBLE);
            holder.type.setText(typeList.get(position));
        }

        return convertView;
    }

    class ViewHolder {
        TextView day;
        TextView type;
    }

}

这里是适配器布局代码

    <TextView
        android:id="@+id/day"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:background="#ffffff"
        android:gravity="center"
        android:textColor="#222222"
        android:textSize="15sp"
        android:visibility="gone" />

    <TextView
        android:id="@+id/type"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:background="#ffffff"
        android:gravity="right|center_vertical"
        android:paddingRight="10dp"
        android:textColor="#222222"
        android:textSize="15sp"
        android:visibility="gone" />

    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="#f0f0f0" />

所有布局我全部用的是LinearLayout
