在Android的活动之间传递值 [英] Passing values between activities in Android

问题描述

我有一个关于Android中的活动之间传递数据的问题。我试图让一个对象Parcelable，它的工作原理，但它的复杂实现每类。我想尝试的值存储作为一个全球性，并在其他活动获取它。我知道，我们应该避免全局变量，但目前我没有任何其他解决方案。任何建议？也许，如果我用了一个集合，它应该是Parcelable吧？

I have a question about passing data between activities in Android. I tried to make an object Parcelable, it works but it's complicated to implement for every class. I want to try to store the value as a global and fetch it in the other activity. I know that we should avoid globals, but at the moment I don't have any other solution. Any advice? Maybe if I used a collection, it should be Parcelable, right??

在此先感谢：）

推荐答案

我有误解，我们的整体构想一种强烈的感觉活动。纵观意图的传递数据，我可以说活动额外的机制的发明一样东西全足够W / O需求交换的大量相互之间的数据。但我还是没有带了Android的核心设计师的一个点。检查<一href=\"http://stackoverflow.com/questions/1694301/good-alternatives-to-share-a-complex-tree-of-objects-between-activities-in-androi\">this螺纹，MB你会发现它有帮助。

I have a strong feeling that we misunderstand the whole conception of Activities. Looking at the intent's extra mechanism of passing data I can say Activity was invented like something all-sufficient w/o need of exchanging large amount of data between each other. But I still havn't got a point of android core designers. Check this thread, mb you'll find it helpfull.
