Full Set of Android tabactivity code (implemented in combination with the layout XML file)

Today, I checked the usage of tabactivity. The articles on the Internet are not comprehensive and are not detailed enough. Therefore, the entire code is specially organized for your convenience. I wrote the source code for Android for the first time. If you do not have any deficiencies, please kindly advise me ~ If you have less time to talk about it, go to the topic below.

 

My development environment is eclipse + Android sdk1.6.

 

Manifest. xml:

<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <manifest xmlns: Android = "http://schemas.android.com/apk/res/android" <br/> package = "com. keven "<br/> Android: versioncode =" 1 "<br/> Android: versionname =" 1.0 "> <br/> <application Android: icon = "@ drawable/icon" Android: Label = "@ string/app_name"> <br/> <activity Android: Name = ". mainframe "<br/> Android: Label =" @ string/app_name "> <br/> <intent-filter> <br/> <action Android: Name =" android. intent. action. main "/> <br/> <category Android: Name =" android. intent. category. launcher "/> <br/> </intent-filter> <br/> </activity> <br/> </Application> <br/> <uses-SDK Android: minsdkversion = "4"/> </P> <p> </manifest>
