Android的：通知调用片段 [英] Android: Notification to call Fragment

问题描述

我可以通知通过设置调用活动 的PendingIntent 的并使用 setLastestEventInfo（）的。如果我想打电话给一个特定的片段是什么，这可能吗？是，我可以覆盖任何方法？据我所知片段并不意图直接合作，而是需要由活动主办。

I can get the Notification to call an activity by setting PendingIntent and using setLastestEventInfo(). What if I want to call to a particular fragment, is that possible? Are the any methods that I can override? As far as I know fragments don't work with intent directly, but need to be hosted by activity.

推荐答案

您可以沿着传递片段的完整类名（ MyFragment.class.getName（））作为额外的意图。然后，有接收意向托管活动，并显示给定为多余的，像这样的片段：

You could pass the full class name of the Fragment (MyFragment.class.getName()) along as an extra in the Intent. Then, have a hosting Activity which receives the intent, and displays the Fragment given as the extra, something like this:

public static final String FRAGMENT_CLASS = "fragment_class";

public void onCreate(Bundle savedState) {
    Intent i = getIntent();
    String fragmentClass = i.getStringExtra(FRAGMENT_CLASS);
    if (!TextUtils.isEmpty(fragmentClass)) {
        Fragment toDisplay = Fragment.instantiate(this, fragmentClass);
        getSupportFragmentManager()
                .beginTransaction()
                .add(R.id.my_root_container, toDisplay, null)
                .commit();
    }
}
