Question

I have an android context menu with various selections and depending on the user selection I want to start an intent. The intent starts the same activity for all the buttons but will contain different String variables depending on the selection. I am currently using a switch, case methodology for my click listener but keep running into ‘duplicate local variable’ problems as I try to eliminate code repetition! If anyone could provide a-bit of pseudo-code that would be even better!

Answer 1

It’s hard to tell without seeing some code, but “duplicate local variables” together with “switch case” makes me think you’re declaring a variable in one of the cases with the same name as a variable from another case.

Code within different cases of the same switch is all in the same scope, unless you surround the code within a case with brackets, like this:

switch(VALUE) {
case A: {
    String string = "";
}
case B: {
    //Same variable name, possible since it's in a different scope now.
    String string = "";
}
}

So either use brackets, or simply make sure you’re using different variable names across the cases.
