Android:如何获取 Intent 的发送者?
android 中有没有办法找到触发 INTENT 的源活动(在目标活动中)?
场景是我有两个活动 A 和 B.两者都触发了调用活动 C 的意图.活动 C 根据其来源显示额外信息.例如.如果呼叫来自 A,则 C 仅显示 2 个文本视图,而在 B 触发意图的情况下,活动 C 显示 3 个文本视图(基本上更多信息基于呼叫者).
The scenario is I have two activities A and B. Both fire an intent to call activity C. Activity C displays extra information based on its source. Eg. If call comes from A then C displays only 2 textviews whereas in the case of intent fired by B the activity C displays 3 textviews (basically more information based on who is the caller).
要确定这一点,我需要知道是谁触发了调用 C 的意图.我该怎么做?
To establish this I need to know who fired the intent calling C. How do I do this?

A better way to do this would be to use Intent extras to pass parameters to the receiver.
