我的应用程序有三个活动说 A - ＆GT; B-＆GT; ç。

My application has three activities say A -> B-> C.

活动A从另一项活动名为通过 startActivityForResult（）。活性B和C也称为类似。我必须调用从通知栏还活性的（如果有一些具体的通知）。

Activity A is called from another activity through startActivityForResult(). Activity B and C are also called similarly. I have to call activity A from notifications bar also (if there is some specific notification).

现在，如果我目前的活动B或C，和我点击通知栏，并调用的活动时，该应用程序进入到活动只有A和输入的数据通过activites B或C不存在。

Now, if currently I am in activity B or C, and I click on Notification bar, and call the activity A, the app goes to Activity A only and data entered through activites B or C do not persist.

我不希望这样的行为。我想，如果我点击的通知，它应该重定向到目前唯一的屏幕。能有人帮助。 （我提到活动：launchMode 为 SingleTask ）。

I don't want such behavior. I want that if I click on Notification, it should redirect to current screen only. Can some one help. (I mentioned activity:launchMode as SingleTask).

推荐答案

您可能能够使用一个静态变量来确定其他数据。我不知道有多少，或者您正在寻找什么类型的数据与其他活动来访问，但。

You may be able to use a static variable to determine other data. I am not sure how much or what type of data you are looking to access from the other Activities, though.

也写入持久性存储可能工作，但同样 - 什么样的数据要存储的模糊性，以及如何使人们难以回答。只要写/读持久存储在 onResume 和 onSuspend 每项活动的methdod（或创建超Activity类和扩展它的A，B和C。

Also writing to persistent storage may work, but again - the vagueness of what data you are storing and how makes it difficult to answer. Just write/read the persistent storage in the onResume and onSuspend methdod of each Activity (or create super Activity class and extend it for A, B and C.
