This is not much of a Android problem (as Activity is class as any other), it's the way Java works.

Java doesn't support multiple inheritance, so classes can only extend one other class.

class A extends B{

}

Even in this case:

class A {

}

class A extends another class - Object - but it is automatically implied without having to specify it.

If you want to ensure some functionality from several sources you will have to use interfaces and the implements keyword:

class A extends B implements C,D,E {

}
