I was wondering what happened if I define a base Activity object with all my activities as subclasses of that. Then I declare a static variable in the base class, will all the subclasses use the SAME static or will there be one per subclass.
For example. My base class:
public class MyBaseActivity extends Activity{
static int myStatic;
...
....
}
Then:
public class MyActivity1 extends MyBaseActivity {
private void someMethod1(){
myStatic = 1;
}
...
....
}
and
public class MyActivity1 extends MyBaseActivity {
private void someMethod2(){
if (myStatic == 1)
doSomething();
}
...
....
}
If I now start MyActivity1 and it sets a value in “myStatic”. It then exits and then I start MyActivity2 – should I still have the value set by the first activity?
In the example above, would the “if” statement be true or false?
I know that if I instantiate Activity1 more than once then obviously I would get the same static variable. However, here I am instantiating a different subclass each time.
I am getting the impression that that is what is happening to me but want to be sure.
Static is static. They will reference the same object.
