先给大家看下效果图：
MenuPopwindow:
package com.cloudeye.android.cloudeye.view; import android.app.Activity; import android.content.Context; import android.graphics.drawable.ColorDrawable; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.AdapterView; import android.widget.BaseAdapter; import android.widget.ImageView; import android.widget.ListView; import android.widget.PopupWindow; import android.widget.TextView; import com.cloudeye.android.cloudeye.R; import com.cloudeye.android.cloudeye.base.MenuPopwindowBean; import java.util.List; /** * Created by 袁磊 on 2016/10/26. */ public class MenuPopwindow extends PopupWindow { private View conentView; private ListView lvContent; public MenuPopwindow(Activity context, List<MenuPopwindowBean> list) { LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); conentView = inflater.inflate(R.layout.menu_popup_window, null); lvContent = (ListView) conentView.findViewById(R.id.lv_toptitle_menu); lvContent.setAdapter(new MyAdapter(context, list)); int h = context.getWindowManager().getDefaultDisplay().getHeight(); int w = context.getWindowManager().getDefaultDisplay().getWidth(); // 设置SelectPicPopupWindow的View this.setContentView(conentView); // 设置SelectPicPopupWindow弹出窗体的宽 this.setWidth(w / 3-30); // 设置SelectPicPopupWindow弹出窗体的高 this.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT); // 设置SelectPicPopupWindow弹出窗体可点击 this.setFocusable(true); this.setOutsideTouchable(true); // 刷新状态 this.update(); // 实例化一个ColorDrawable颜色为半透明 ColorDrawable dw = new ColorDrawable(0000000000); // 点back键和其他地方使其消失,设置了这个才能触发OnDismisslistener ，设置其他控件变化等操作 this.setBackgroundDrawable(dw); // mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog); // 设置SelectPicPopupWindow弹出窗体动画效果 this.setAnimationStyle(R.style.AnimationPreview); } public void setOnItemClick(AdapterView.OnItemClickListener myOnItemClickListener) { lvContent.setOnItemClickListener(myOnItemClickListener); } class MyAdapter extends BaseAdapter { private List<MenuPopwindowBean> list; private LayoutInflater inflater; public MyAdapter(Context context, List<MenuPopwindowBean> list) { inflater = LayoutInflater.from(context); this.list = list; } @Override public int getCount() { return list == null ? 0 : list.size(); } @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) { Holder holder = null; if (convertView == null) { convertView = inflater.inflate(R.layout.menu_popup_window_item, null); holder = new Holder(); holder.ivItem = (ImageView) convertView.findViewById(R.id.iv_menu_item); holder.tvItem = (TextView) convertView.findViewById(R.id.tv_menu_item); convertView.setTag(holder); } else { holder = (Holder) convertView.getTag(); } holder.ivItem.setImageResource(list.get(position).getIcon()); holder.tvItem.setText(list.get(position).getText()); return convertView; } class Holder { ImageView ivItem; TextView tvItem; } } /** * 显示popupWindow * * @param parent */ public void showPopupWindow(View parent) { if (!this.isShowing()) { // 以下拉方式显示popupwindow this.showAsDropDown(parent); } else { this.dismiss(); } } }
MenuPopwindow布局：
<"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:paddingRight="10dp"> <ListView android:id="@+id/lv_toptitle_menu" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@mipmap/back_toptitle_menu" /> </LinearLayout>
Adapter中的Item布局文件：
<"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:gravity="center" android:orientation="horizontal" android:paddingBottom="10dp" android:paddingTop="10dp"> <ImageView android:id="@+id/iv_menu_item" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_vertical" android:layout_marginRight="10dp" android:src="@mipmap/icon_menu_item_edit" /> <TextView android:id="@+id/tv_menu_item" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_vertical" android:text="测试" android:textColor="@color/black" android:textSize="18sp" /> </LinearLayout>
使用：
int[] icons = {R.mipmap.icon_menu_item_edit, R.mipmap.icon_menu_item_delete}; String[] texts = {"编辑", "删除"}; List<MenuPopwindowBean> list = new ArrayList<>(); MenuPopwindowBean bean = null; for (int i = 0; i < icons.length; i++) { bean = new MenuPopwindowBean(); bean.setIcon(icons[i]); bean.setText(texts[i]); list.add(bean); } MenuPopwindow pw = new MenuPopwindow(PersonalImgPlayActivity.this, list); pw.setOnItemClick(myOnItemClickListener); pw.showPopupWindow(findViewById(R.id.img_top1_share));//点击右上角的那个button
