Android: Count number of cases in switch statement, know when last case
I am busy working on an app with multiple switch statement that each have a different number of cases.
switch(variable){
case: 0
//do something
case: 1
//do something
case: 3
//do something
I can iterate through the cases by using variable = variable +1. That works fine. My problem is being able to tell when the last case in the switch statement has been reached so that I can perform a different action.
How do I know when the count is at the last case? What is the code for that?
I appreciate your time.

@josh_gom3z in the last case a button will show that will offer the user the option to do something else. I could add it to the last case but I would have to go through each switch statement and there are a lot so I am trying to find a way to count the cases in a given switch statement in order to be able to tell when the last case for a particular switch statement has been reached.

You can use default case for your problem.
switch(variable){
case: 0
//do something
break;
case: 1
//do something
break;
case: 3
//do something
break;
default:
// Here you can run your different action
break;
}
You have to also define the max value for your variable so that when your variable value reaches to that max value it stops incrementing the variable value.
