Android实现模仿UCweb菜单效果的方法

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"?>
<linearlayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
 android:background="#50000000"
 android:layout_height="fill_parent"
 android:gravity="bottom|center_horizontal">
 <linearlayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="320dip"
  android:background="@drawable/bkg2"
  android:id="@+id/popdialog"
  android:layout_height="250dip"
  android:gravity="center_vertical|center_horizontal"
  >
  <gridview
   android:id="@+id/gridview"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   android:numcolumns="4"
   android:verticalspacing="10dip"
   android:horizontalspacing="10dip"
   android:stretchmode="columnwidth"
   android:gravity="center"
   />
 </linearlayout>
</linearlayout>

item_menu.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>

2、用popupwindow作为菜单显示容器：

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itemclick
pop.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：

@override
public 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();
 }
});
