底部彈出listPopWindow

實現底部彈出一個listview選擇框的原理是：製作一個含有listview的PopupWindow，控制PopupWindow在activity底部彈出。

如何製作一個含有list的popupWindow?
只需要一個佈局文件盛放你想要的pop佈局，和一個繼承PopupWindow的類，來重寫PopupWindow。看代碼更直觀
SelectListPopupWindow.java實現類

package com.example.picpopupwindow;

import java.util.ArrayList;
import java.util.HashMap;


import android.app.Activity;
import android.content.Context;
import android.graphics.drawable.ColorDrawable;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnTouchListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.PopupWindow;

public class SelectListPopupWindow extends PopupWindow {


    private View mMenuView;
    private ListView listView;
    private PopListAdapter adapter ;
    private ArrayList<HashMap<String, Object>> list;

    public SelectListPopupWindow(Activity context,OnClickListener itemsOnClick, ArrayList<HashMap<String, Object>> datalist) {//, OnItemClickListener itemclick
        super(context);
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        mMenuView = inflater.inflate(R.layout.pop_list_layout, null);
        listView = (ListView) mMenuView.findViewById(R.id.pop_list_layout_listview);
//      list = new ArrayList<HashMap<String,String>>();
//      HashMap<String, String> map =new HashMap<String, String>();
//      map.put("name", "山東");
//      list.add(map);
//      HashMap<String, String> map1 =new HashMap<String, String>();
//      map1.put("name", "河北");
//      list.add(map1);
        this.list =datalist;
        adapter = new PopListAdapter(context, list);
        listView.setAdapter(adapter);

        //設置SelectPicPopupWindow的View
        this.setContentView(mMenuView);
        //設置SelectPicPopupWindow彈出窗體的寬
        this.setWidth(LayoutParams.FILL_PARENT);
        //設置SelectPicPopupWindow彈出窗體的高
        this.setHeight(LayoutParams.WRAP_CONTENT);
        //設置SelectPicPopupWindow彈出窗體可點擊
        this.setFocusable(true);
        //設置SelectPicPopupWindow彈出窗體動畫效果
        this.setAnimationStyle(R.style.AnimBottom);
        //實例化一個ColorDrawable顏色爲半透明
        ColorDrawable dw = new ColorDrawable(0xb0000000);
        //設置SelectPicPopupWindow彈出窗體的背景
        this.setBackgroundDrawable(dw);
        //mMenuView添加OnTouchListener監聽判斷獲取觸屏位置如果在選擇框外面則銷燬彈出框
        mMenuView.setOnTouchListener(new OnTouchListener() {

            public boolean onTouch(View v, MotionEvent event) {

                int height = mMenuView.findViewById(R.id.pop_list_layout_listview).getTop();
                int y=(int) event.getY();
                if(event.getAction()==MotionEvent.ACTION_UP){
                    if(y<height){
                        dismiss();
                    }
                }               
                return true;
            }
        });

        mMenuView.setOnClickListener(itemsOnClick);
//      listView.setOnItemClickListener(itemclick);
    }


    public ListView getListView() {
        return listView;
    }


    public void setListView(ListView listView) {
        this.listView = listView;
    }


}

pop_list_layout.xml佈局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center_horizontal"
    android:orientation="vertical" >

    <ListView
        android:id="@+id/pop_list_layout_listview"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/white" />

</LinearLayout>

以下是在activity中如何調用你生成的SelectListPopupWindow

final ArrayList<HashMap<String,Object>> list = new ArrayList<HashMap<String,Object>>();
                HashMap<String, Object> map =new HashMap<String, Object>();
                map.put("name", "山東");
                list.add(map);
                HashMap<String, Object> map1 =new HashMap<String, Object>();
                map1.put("name", "河北");
                list.add(map1);
                menuWindow = new SelectListPopupWindow(MainActivity.this, itemsOnClick,list);
                menuWindow.getListView().setOnItemClickListener(new OnItemClickListener() {

                    public void onItemClick(AdapterView<?> arg0, View arg1,
                            int position, long arg3) {
                        HashMap<String,Object> map = list.get(position);
                        Toast.makeText(MainActivity.this, map.get("name").toString(), Toast.LENGTH_SHORT).show();
////                     
                    }
                });
                //顯示窗口
                menuWindow.showAtLocation(MainActivity.this.findViewById(R.id.main), Gravity.BOTTOM|Gravity.CENTER_HORIZONTAL, 0, 0); //設置layout在PopupWindow中顯示的位置
