跳出方法从匿名内部类 [英] Break out of a method from anonymous inner class

问题描述

我有一个方法：

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();
}

这里的东西，如果我的code到达 ESCAPE （即用户决定不覆盖），我要彻底退出方法。我曾尝试...

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...

• 更改的someMethod（）来返回一个布尔值，然后从负按钮返回，但它不会让我，因为它是一个无效的内部方法中。


• 从 ESCAPE 在外部抓到，但是编译器不会让我抛出一个异常，因为 DialogInterface.OnClickListener 不会抛出。


• 使用破语句离开为循环，但这并不能工作。

• 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.

这也将是可以接受的只是离开为循环。我可以解释这一点。我用尽了一切我能找到和我在我束手无策。

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.

推荐答案

您可以抛出一个RuntimeException或其子类之一。编译器不会抱怨。

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