问题描述
限时送ChatGPT账号..似乎(至少)有两种方式可以发送意图 在安卓中:
There seem to be (at least) two ways to send Intents in Android:
PendingIntent.send(...)Activity.startIntentSenderForResult(PendingIntent.getIntentSender(), ...)
除了后者只能从 API 级别 5 开始工作并且结果以不同的方式传回这一事实(通过 PendingIntent.OnFinished 与 Activity.onActivityResult(...)) 有什么基本的两者的区别?
Other than the fact that the latter only works starting API level 5 and that the results are passed back in a different way (via PendingIntent.OnFinished vs. Activity.onActivityResult(...)) is there any fundamental difference between the two?
我发现第一个更方便，因为它可以完全封装在库中，而无需调用 Activity 覆盖 onActivityResult(...) 以转发结果 (像这样:糟糕！).仍然可以使用这种方法吗?
I find the first one a lot more convenient as it can be entirely encapsulated inside a library without requiring the calling activity to override onActivityResult(...) to forward the result (like this: yuck!). Is it ok to still use that approach?
快速澄清一下，因为我看到有人在另一个问题上抱怨这个: ; 上面的方法不是静态方法.我这样写它们只是为了可读性.
推荐答案
似乎这两种方法非常不同:
Seems like these two approaches are very different:
start...forResult(...) 方法以允许将结果返回给执行 start 的活动的方式启动意图或子活动...forResult(...).结果将传递回活动的 onActivityResult(...) 方法.启动意图或子活动的所有其他方式(包括 PendingIntent.send(...))都以即发即忘的方式起作用，并且不允许任何结果被退回.OnFinished 处理程序在发送启动后立即调用，无论是否需要一段时间才能完成.因此，传递到此处理程序的数据不一定与您通过 onActivityResult(...) 接收的数据有任何关系.事实上，在我的例子中，OnFinished 处理程序总是在子活动的对话框出现之前立即被调用，resultCode 是 Activity.RESULT_CANCELED.
The start...forResult(...) methods start an intent or sub-activity in a way that allows for a result to be returned to the activity that executed the start...forResult(...). The result will be passed back to the activity's onActivityResult(...) method.
All other ways of launching intents or sub-activities (including PendingIntent.send(...)) act in a fire-and-forget-manner and don't allow for any results to be returned. The OnFinished handler is called as soon as the launch is sent, whether or not it takes a while to complete. The data passed into this handler, therefore, does not necessarily have anything to do with what you would otherwise receive via onActivityResult(...). In fact, in my case, the OnFinished handler is always called right away, before the dialog of the sub-activity even shows up, with a resultCode of Activity.RESULT_CANCELED.
什么乱七八糟的...
