如何知道哪些应用程序是由Intent.createChooser选择？ [英] How to tell which app was selected by Intent.createChooser?

问题描述

code：

        Intent launchIntent = new Intent(Intent.ACTION_MAIN);
        launchIntent.addCategory(Intent.CATEGORY_HOME);
        Intent chooser  = Intent.createChooser(launchIntent, "Complete Action using..");
        activity.startActivity(chooser);

我看不出有什么方法来判断哪些意图（HOME类启动器）被选中。没有Inent.addOnActionSetListener，也没有chooser.addOnIntentChosenListener等，所以我怎么能知道哪些选择？难道还是我写我自己的选择器来呢？

I don't see any way to tell which Intent (HOME category launcher) was selected. There is no Inent.addOnActionSetListener, and no chooser.addOnIntentChosenListener etc. So how can I tell which was selected? Do Or do I have to write my own chooser for this?

推荐答案

在Android 5.1+，你可以使用<一个href="http://developer.android.com/reference/android/content/Intent.html#createChooser%28android.content.Intent,%20java.lang.CharSequence,%20android.content.IntentSender%29"相对=nofollow>的三参数版 createChooser（）方法，其中最后一个参数是 IntentSender ，你可以用它来找出被选中。

On Android 5.1+, you can use the three-parameter edition of the createChooser() method, where the last parameter is an IntentSender that you can use to find out what was chosen.

在此之前的Andr​​oid 5.1，没有什么在Android中，让你知道什么样的用户选择。

Prior to Android 5.1, there is nothing in Android to let you know what the user chose.
