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, 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.setOutsideTouchable(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>
