/*而除了专门为按钮点击实现的DialogInterFace.OnClickListener事件外，DialogInterface还提供了一些其他的事件，供Dialog对象响应，这些事件只是对Dialog声明周期各个状态的响应，一看就明白了，就不再详细讲解了，下面是这几个事件的说明：

interface DialogInterface.OnCancelListener：当对话框调用cancel()方法的时候触发。
interface DialogInterface.OnDismissListener：当对话框调用dismiss()方法的时候触发。
interface DialogInterface.OnShowListener：当对话框调用show()方法的时候触发。
interface DialogInterface.OnMultiChoiceListener：当对话框使用多选列表，并且选中的时候触发*/
