1.首页

package com.yskj.jh.demopopupwindow;import androID.content.Context;import androID.graphics.drawable.BitmapDrawable;import androID.support.v7.app.AppCompatActivity;import androID.os.Bundle;import androID.vIEw.LayoutInflater;import androID.vIEw.VIEw;import androID.vIEw.VIEwGroup;import androID.Widget.AdapterVIEw;import androID.Widget.BaseAdapter;import androID.Widget.button;import androID.Widget.linearLayout;import androID.Widget.ListVIEw;import androID.Widget.PopupWindow;import androID.Widget.TextVIEw;import androID.Widget.Toast;import java.util.ArrayList;public class MainActivity extends AppCompatActivity { private button button; private PopupWindow kindsPopupWindow; @OverrIDe protected voID onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  setContentVIEw(R.layout.activity_main);  button = (button) findVIEwByID(R.ID.button);  button.setonClickListener(new VIEw.OnClickListener() {   @OverrIDe   public voID onClick(VIEw v) {    getKindPopupWindow();   }  }); } private voID getKindPopupWindow() {  final ArrayList kindsList = new ArrayList();  kindsList.add("全部分类");  kindsList.add("今日上线");  kindsList.add("美食");  kindsList.add("酒店");  kindsList.add("旅游");  LayoutInflater inflater = LayoutInflater.from(this);  // 引入窗口配置文件  VIEw vIEw = inflater.inflate(R.layout.pop_local_kind,null);  // 创建PopupWindow对象  kindsPopupWindow = new PopupWindow(vIEw,linearLayout.LayoutParams.WRAP_CONTENT,false);  //设置popupWindow宽  kindsPopupWindow.setWIDth(button.getWIDth());  ListVIEw ListVIEw = (ListVIEw) vIEw.findVIEwByID(R.ID.List);  PopAdapter adapter = new PopAdapter(MainActivity.this,kindsList);  ListVIEw.setAdapter(adapter);  // 需要设置一下此参数，点击外边可消失  kindsPopupWindow.setBackgroundDrawable(new BitmapDrawable());  //设置点击窗口外边窗口消失  kindsPopupWindow.setoutsIDe@R_419_5985@able(true);  // 设置此参数获得焦点，否则无法点击  kindsPopupWindow.setFocusable(true);  //设置popupWindow显示位置  kindsPopupWindow.showAsDropDown(button);  ListVIEw.setonItemClickListener(new AdapterVIEw.OnItemClickListener() {   @OverrIDe   public voID onItemClick(AdapterVIEw<?> adapterVIEw,VIEw vIEw,int i,long l) {    Toast.makeText(MainActivity.this,i+"pop",Toast.LENGTH_SHORT).show();    button.setText(kindsList.get(i).toString());    kindsPopupWindow.dismiss();   }  }); } //pop适配器 private class PopAdapter extends BaseAdapter {  private Context context;  private ArrayList<String> List;  public PopAdapter(Context context,ArrayList<String> List) {   this.context = context;   this.List = List;  }  @OverrIDe  public int getCount() {   if (List==null||List.size()==0){    return 0;   }   return List.size();  }  @OverrIDe  public Object getItem(int i) {   return List.get(i);  }  @OverrIDe  public long getItemID(int i) {   return i;  }  @OverrIDe  public VIEw getVIEw(int i,VIEw convertVIEw,VIEwGroup vIEwGroup) {   VIEwHolder holder = null;   if(convertVIEw==null){    holder = new VIEwHolder();    convertVIEw = LayoutInflater.from(context).inflate(R.layout.item_pop_local_kind,null);    holder.textVIEw = (TextVIEw) convertVIEw.findVIEwByID(R.ID.item_text);    convertVIEw.setTag(holder);   }else{    holder=(VIEwHolder)convertVIEw.getTag();   }   holder.textVIEw.setText(List.get(i).toString());   return convertVIEw;  }  private class VIEwHolder {   TextVIEw textVIEw;  } }}

2.首页布局

<?xml version="1.0" enCoding="utf-8"?><linearLayout xmlns:androID="http://schemas.androID.com/apk/res/androID" androID:layout_wIDth="match_parent" androID:layout_height="match_parent" androID:orIEntation="vertical" > <button  androID:ID="@+ID/button"  androID:layout_wIDth="wrap_content"  androID:layout_height="wrap_content"  androID:text="Show PopupWindow" /></linearLayout>

3.popupwindow布局，可根据情况自行布局，这里是demo布局

<?xml version="1.0" enCoding="utf-8"?><linearLayout xmlns:androID="http://schemas.androID.com/apk/res/androID" androID:layout_wIDth="match_parent" androID:layout_height="match_parent" androID:orIEntation="vertical" androID:background="#ffffff"> <ListVIEw  androID:ID="@+ID/List"  androID:layout_wIDth="match_parent"  androID:layout_height="wrap_content"  androID:background="#888888"> </ListVIEw></linearLayout>

4.popupwindow条目布局

<?xml version="1.0" enCoding="utf-8"?><linearLayout xmlns:androID="http://schemas.androID.com/apk/res/androID" androID:layout_wIDth="match_parent" androID:layout_height="match_parent" androID:orIEntation="vertical" androID:background="@color/white"> <TextVIEw  androID:ID="@+ID/item_text"  androID:layout_wIDth="match_parent"  androID:layout_height="40dp"  androID:gravity="center"  androID:text="pop"  androID:textcolor="#f08e1f"  androID:background="#eeeeee"  /></linearLayout>
