Android:获取最新意图 [英] Android: get most recent intent

问题描述

如何获取发送给活动的最后意图?

How can I get the last intent sent to an activity?

onNewIntent()的文档建议我需要执行以下操作:

The docs for onNewIntent() suggest I would need to do something like this:

class MyActivity {
    public void onNewIntent(Intent intent){
        setIntent(intent);
        reactToIntentAndDoStuff()
        super.onNewIntent(Intent intent);
    }
    public void onCreate(){
        reactToIntentAndDoStuff()
        super.onCreate();
    }
    public void onResume(){
        reactToIntentAndDoStuff()
        super.onResume();
    }
    public void reactToIntentAndDoStuff(){
        Intent intent = getIntent();
    }
}

这看起来正确吗?或者，还有更好的方法?我的活动的launchMode将是singleTop.无论是否已实例化，它都将需要以大致相同的方式对相同的Intent做出反应.

Does this look about right? Or is there a better way? My activity's launchMode will be singleTop. It will need to react to the same Intent in more or less the same way, whether it's already instantiated or not.

推荐答案

我认为这是正确的方法:) 请检查您是否真的需要在onResume()方法中调用reactToIntentAndDoStuff().我认为不需要.

I think this is the correct way :) Please check if you really need to call reactToIntentAndDoStuff() in onResume() method. I think its not needed.

super.onCreate();应该是onCreate()方法的第一行.

super.onCreate(); should be first line in onCreate() method.

getIntent()返回一个Intent，它是Activity首次启动时收到的.除非我们调用setIntent(newIntent)方法，否则不会更新.

getIntent() returns an Intent which was received when Activity launched first time. This does not update unless we call setIntent(newIntent) method.
