Question

I have a method:

void someMethod(String someString)
    final String[] testAgainst = {...};
    ....
    for(int i = 0; i < testAgainst.length; i++) {
        if (someString.equals(testAgainst[i])) {
            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setMessage("Strings are the same! Overwrite?")
                   .setTitle("Blah Blah Blah")
                   .setCancelable(false)
                   .setPositiveButton("Overwrite", new DialogInterface.OnClickListener() {

                       public void onClick(DialogInterface di, int which) {
                           someAction()
                       }
                   })

                   .setNegativeButton("Nah", new DialogInterface.OnClickListener() {

                       public void onClick(DialogInterface di, int which) {
                           ESCAPE
                       }
                   });
            AlertDialog dialog = builder.create();
        }
    }

    doSomeOtherStuff();
}

Here’s the thing, if my code reaches ESCAPE (that is, the user decides not to overwrite), I want to exit the method completely. I have tried…

• changing someMethod() to return a boolean, then returning it from the negative button, but it won’t let me because it’s within a void internal method.
• throwing an exception from ESCAPE to be caught externally, but the compiler won’t let me because DialogInterface.OnClickListener doesn’t throw.
• using a break statement to leave the for loop, but that doesn’t work either.

It would also be acceptable to simply leave the for loop. I can account for that. I’ve tried everything I can find and I’m at my wit’s end.

You can throw a RuntimeException or one of its subclasses. The compiler won’t complain about it.
