Android: Improving customized Menu (TabMenu) in 18 articles)

The Chinese New Year is approaching. I would like to wish you a happy New Year!
People who have used UCWEB-Android should be impressed with their special menus and make the menus into Tab-menus (paging menus supported ), it can accommodate richer content than the traditional menu of Android (more menu items of Android are scaled down in [more]). For more information, see the example on the Internet (by CoffeeCole, email: longkefan@foxmail.com) to simplify and encapsulate the example so that it can be integrated into your own framework as a composite control.

Let's take a look at the effect of the program running in this article:

TabMenu itself is a PopupWindow, and two GridView are put on the PopupWindow. The first GridView is a page tag, which is located at the top of the PopupWindow, and the second GridView is the menu, which is located at the main body of the PopupWindow. This article uses the following code to implement the pop-up/exit animation of PopupWindow:

Add the anim sub-directory to the res folder of the project, and then create the file popup_enter.xml:

<? Xml version = "1.0" encoding = "UTF-8"?>
<Set xmlns: android = "http://schemas.android.com/apk/res/android">
<Translate android: fromYDelta = "100% p" android: toYDelta = "0" android: duration = "1000"/>
<Alpha android: fromAlpha = "0.0" android: toAlpha = "1.0" android: duration = "1000"/>
</Set>
 

Create the popup_exit.xml file:

<? Xml version = "1.0" encoding = "UTF-8"?>
<Set xmlns: android = "http://schemas.android.com/apk/res/android">
<Translate android: fromYDelta = "0" android: toYDelta = "100% p" android: duration = "1000"/>
<Alpha android: fromAlpha = "1.0" android: toAlpha = "0.0" android: duration = "1000"/>
</Set>
 

Create the file popup_animation.xml in the project's values Folder:

<? Xml version = "1.0" encoding = "UTF-8"?>
<Resources>
<Style name = "PopupAnimation" parent = "android: Animation">
<Item name = "android: windowEnterAnimation"> @ anim/popup_enter </item>
<Item name = "android: javaswexitanimation"> @ anim/popup_exit </item>
</Style>
</Resources>

 

The source code of main. xml is as follows:

<? Xml version = "1.0" encoding = "UTF-8"?>
<LinearLayout android: id = "@ + id/LinearLayout01"
Android: layout_width = "fill_parent" android: layout_height = "fill_parent"
Xmlns: android = "http://schemas.android.com/apk/res/android">
<TextView android: id = "@ + id/TextView01" android: layout_height = "wrap_content"
Android: layout_width = "fill_parent" android: text = "extended Menu ---- hellogv"> </TextView>
</LinearLayout>
 

The source code of TabMenu. java is as follows:
