如何从意图获得额外的日期? [英] How to get Date extra from an intent?

问题描述

我正在打包意图，我添加的Extras之一是日期对象，如下所示:

I am packing an intent and one of the Extras I add is a date object, like this:

intent.putExtra(DATE_EXTRA, t.getDate());

后来，当我阅读其他内容时，我会尝试像这样获取日期:

Later, when I reading the extras, I try to get the Date like this:

this.date = new Date(intent.getExtras().getString(DATE_EXTRA));

但是，这将返回有关String为空的错误.我不认为以上方法是正确的方法，因为我没有在寻找字符串，但是我无法在任何地方找到intent.getDateExtra()方法.我该怎么办?

However, this returns an error about the String being empty. I don't think the above is the right way to do it, because I am not looking for a string, but I have not been able to find an intent.getDateExtra() method anywhere. What do I do?

我知道日期已正确传递，因为我可以在调试时看到它:

I know that the date was passed properly, because I can see it while debugging:

推荐答案

替换:

this.date = new Date(intent.getExtras().getString(DATE_EXTRA));

具有:

this.date = (Date)intent.getSerializableExtra(DATE_EXTRA);

看看是否有帮助.
