PopupWindow实现弹出菜单

     在使用UC-WebBrowser时，你会发现它的弹出菜单跟系统自带的菜单不一样。它实现更多菜单选项的显示和分栏。其实，它的本身是PopupWindow或者是AlertDialog对话框，在里面添加两个GridView控件，一个是菜单标题栏，一个是菜单选项。菜单选项视图的切换可以通过适配器的变换，轻松地实现。该实例下载路径：http://download.csdn.net/source/3275759

          一、运行截图：

           

 

             

        二、实现要点：

        （1）屏蔽系统弹出的菜单：

          1、首先创建至少一个系统的菜单选项

        

[java] view plain copy print ?

1. @Override  
2.     public boolean onCreateOptionsMenu(Menu menu) {  
3.           
4.         menu.add("menu");  
5.         return super.onCreateOptionsMenu(menu);  
6.     }  

@Override public boolean onCreateOptionsMenu(Menu menu) { menu.add("menu"); return super.onCreateOptionsMenu(menu); }

          2、在onMenuOpened方法里显示自己的菜单视图，并返回FALSE。

       

[java] view plain copy print ?

1. @Override  
2.     public boolean onMenuOpened(int featureId, Menu menu) {  
3.   
4.         myMenu.showAtLocation(findViewById(R.id.layout), Gravity.BOTTOM, 0,0);  
5.           
6.         return false;   // true--显示系统自带菜单；false--不显示。   
7.     }  

@Override public boolean onMenuOpened(int featureId, Menu menu) { myMenu.showAtLocation(findViewById(R.id.layout), Gravity.BOTTOM, 0,0); return false; // true--显示系统自带菜单；false--不显示。 }

        （2）点击菜单栏，切换菜单视图时，只要重新设置当前的适配器对象就可以。

        

[java] view plain copy print ?

1. gv_body.setAdapter(bodyAdapter[arg2]);  //改变选项视图  

gv_body.setAdapter(bodyAdapter[arg2]); //改变选项视图

         （3）继承PopupWindow，重写一个类实现弹出对话框，主要是为了更好更简便实现弹出菜单的样式和事件响应等等。

         

[java] view plain copy print ?

1. public class MyDefinedMenu extends PopupWindow { 。。。}  

public class MyDefinedMenu extends PopupWindow { 。。。}

        三、 具体代码如下：

        （1）布局：

          

[xhtml] view plain copy print ?

1. <?xml version="1.0" encoding="utf-8"?>  
2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
3.     android:id="@+id/layout"  
4.     android:orientation="vertical"  
5.     android:layout_width="fill_parent"  
6.     android:layout_height="fill_parent"  
7.     >  
8. </LinearLayout>  

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/layout" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > </LinearLayout>

          （2）程序代码
