本文实例讲述了android实现模仿ucweb菜单效果的方法。分享给大家供大家参考。具体如下：
ucweb的菜单看起来不错，自己模仿做一个，思路实现如下：
1、保留menu按键作用
2、用popupwindow作为菜单显示容器
3、用gridview显示所有子菜单
代码如下：
1、布局文件：
popupwindow.xml：

<?xml version="1.0" encoding="utf-8"?><relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/relativelayout_item" android:layout_width="fill_parent" android:layout_height="wrap_content" android:paddingbottom="5dip"> <imageview android:id="@+id/item_image" android:layout_centerhorizontal="true" android:layout_width="40dip" android:layout_height="40dip"> </imageview> <textview android:layout_below="@id/item_image" android:id="@+id/item_text" android:layout_centerhorizontal="true" android:layout_width="wrap_content" android:layout_height="wrap_content" style="@style/text.location" android:text="选项"></textview></relativelayout> |

view view = this.getlayoutinflater().inflate(r.layout.popwindowdemo, null);pop = new popupwindow(view,320,450);//大小设置为全屏幕，这里硬编码的，可修改pop.setoutsidetouchable(false);pop.setbackgrounddrawable(new bitmapdrawable());pop.setfocusable(true);//如果不加这个，grid不会响应itemclickpop.settouchinterceptor(new ontouchlistener() {public boolean ontouch(view v, motionevent event) { // todo auto-generated method stub if (event.gety()<240){ //这里处理，当点击gridview以外区域的时候，菜单关闭 if (pop.isshowing()) pop.dismiss(); } log.d("demo", "popupwindow::ontouch >>> view: " + v + ", event: " + event); return false;}}); |
3、初始化gridview：

/** 菜单图片 **/int[] menu_image_array = { r.drawable.menu_search, r.drawable.menu_filemanager, r.drawable.menu_downmanager, r.drawable.menu_fullscreen, r.drawable.menu_inputurl, r.drawable.menu_bookmark, r.drawable.menu_bookmark_sync_import, r.drawable.menu_sharepage, r.drawable.menu_quit, r.drawable.menu_nightmode, r.drawable.menu_refresh, r.drawable.menu_more };/** 菜单文字 **/string[] menu_name_array = { "搜索", "文件管理", "下载管理", "全屏", "网址", "书签", "加入书签", "分享页面", "退出", "夜间模式", "刷新", "更多" };/*** 构造菜单adapter* * @param menunamearray* 名称* @param imageresourcearray* 图片* @return simpleadapter*/private simpleadapter getmenuadapter(string[] menunamearray,int[] imageresourcearray) { arraylist<hashmap<string, object>> data = new arraylist<hashmap<string, object>>(); for (int i = 0; i < menunamearray.length; i++) { hashmap<string, object> map = new hashmap<string, object>(); map.put("itemimage", imageresourcearray[i]); map.put("itemtext", menunamearray[i]); data.add(map); } simpleadapter simperadapter = new simpleadapter(this, data, r.layout.item_menu, new string[] { "itemimage", "itemtext" }, new int[] { r.id.item_image, r.id.item_text }); return simperadapter;}menugrid = (gridview) view.findviewbyid(r.id.gridview); menugrid.setadapter(getmenuadapter(menu_name_array, menu_image_array)); |
4、注册menu弹起事件：

@overridepublic boolean oncreateoptionsmenu(menu menu) { // todo auto-generated method stub pop.showatlocation(findviewbyid(r.id.mainfrm), gravity.center|gravity.bottom, 0, 0); return false;//super.oncreateoptionsmenu(menu); } |
5、注册menu子菜单单击事件：

menugrid.setonitemclicklistener(new onitemclicklistener() { public void onitemclick(adapterview<?> arg0, view arg1, int arg2, long arg3) { log.v("demo", "menugrid.setonitemclicklistener: "+arg2+" "+arg3); toast.maketext(uimenu.this, "click"+arg2, toast.length_short).show(); if (pop.isshowing()) //关闭菜单 pop.dismiss(); }}); |
