变量的范围

Question

如何在此代码中获取方法参数"myInteger"的值.

public void myMethod(int myInteger) {
    View.OnClickListener myClearHandler = new View.OnClickListener() {
        public void onClick(View v) {
            //***How can I get the value of "myInteger" here?***
        }
    };
}

假设你只是想读它,你只需要让它最终:

public void myMethod(final int myInteger) {
    View.OnClickListener myClearHandler = new View.OnClickListener() {
        public void onClick(View v) {
            int foo = myInteger;
        }
    };
}

在Java中,只能final在匿名内部类中访问参数和局部变量.
