An extend and import issue - Android

Here is the deal : I need to extends two different classes in Android. An example: In MainActivity.class I need to extends first TabActivity to use the tabs and getTabHost(); and in the same class I need to extends for example Li开发者_如何学PythonstActivity or something else...How can I do that? Maybe my question is a little stupid but... Thanks anyway!

You can extends either TabActivity or ListActivity in your main Activity.You can't extends two all together because java does not support multiple inheritence.After extending any one create the reference of another to use in your activity.

Your MainActivity doesn't need to extend TabActivity and ListActivity at the same time.

Only MainActivity needs to extend TabActivity and you can use a different Activity which extends ListActivity as the content of one or more of the tabs.

Here is the really good official documentation which has an example of what I'm talking about : http://developer.android.com/resources/tutorials/views/hello-tabwidget.html
