底部弹出listPopWindow

实现底部弹出一个listview选择框的原理是：制作一个含有listview的PopupWindow，控制PopupWindow在activity底部弹出。

如何制作一个含有list的popupWindow?

只需要一个布局文件盛放你想要的pop布局，和一个继承PopupWindow的类，来重写PopupWindow。看代码更直观

SelectListPopupWindow.java实现类

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", "山东");
//      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);

//设置SelectPicPopupWindow的View
this.setContentView(mMenuView);
//设置SelectPicPopupWindow弹出窗体的宽
this.setWidth(LayoutParams.FILL_PARENT);
//设置SelectPicPopupWindow弹出窗体的高
this.setHeight(LayoutParams.WRAP_CONTENT);
//设置SelectPicPopupWindow弹出窗体可点击
this.setFocusable(true);
//设置SelectPicPopupWindow弹出窗体动画效果
this.setAnimationStyle(R.style.AnimBottom);
//实例化一个ColorDrawable颜色为半透明
ColorDrawable dw = new ColorDrawable(0xb0000000);
//设置SelectPicPopupWindow弹出窗体的背景
this.setBackgroundDrawable(dw);
//mMenuView添加OnTouchListener监听判断获取触屏位置如果在选择框外面则销毁弹出框
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布局

<?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中如何调用你生成的SelectListPopupWindow

final ArrayList<HashMap<String,Object>> list = new ArrayList<HashMap<String,Object>>();
HashMap<String, Object> map =new HashMap<String, Object>();
map.put("name", "山东");
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();
////
}
});
//显示窗口
menuWindow.showAtLocation(MainActivity.this.findViewById(R.id.main), Gravity.BOTTOM|Gravity.CENTER_HORIZONTAL, 0, 0); //设置layout在PopupWindow中显示的位置
