super.onUpdate（）在AppWidgetProvider建议？ [英] super.onUpdate() in AppWidgetProvider recommend?

问题描述

我想，如果在调用super.onUpdate（弄清楚）正在开发一个AppWidgetProvider时推荐。

I'm trying to figure out if calling super.onUpdate() is recommend when developing an AppWidgetProvider.

public class MyAppWidgetProvider extends AppWidgetProvider {
  @Override
  public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    super.onUpdate(context, appWidgetManager, appWidgetIds);
    // My code starts here
    ...
  }
}

我不知道，因为它需要调用super.onCreate开发一个活动时，（）。但我找不到在JavaDoc类似的事情：
<一href=\"http://developer.android.com/reference/android/appwidget/AppWidgetProvider.html#onUpdate(android.content.Context\" rel=\"nofollow\">http://developer.android.com/reference/android/appwidget/AppWidgetProvider.html#onUpdate(android.content.Context, android.appwidget.AppWidgetManager，INT []）

I'm wondering because it is necessary to call super.onCreate() when developing an Activity. But I can't find anything similar in the JavaDoc: http://developer.android.com/reference/android/appwidget/AppWidgetProvider.html#onUpdate(android.content.Context, android.appwidget.AppWidgetManager, int[])

我也查了Android源（2.2和4.0）：

I also checked the Android sources (2.2 and 4.0):

<一个href=\"http://grep$c$c.com/file/repository.grep$c$c.com/java/ext/com.google.android/android/2.2_r1.1/android/appwidget/AppWidgetProvider.java\" rel=\"nofollow\">http://grep$c$c.com/file/repository.grep$c$c.com/java/ext/com.google.android/android/2.2_r1.1/android/appwidget/AppWidgetProvider.java

现在的方法不执行任何操作，但也许会做在以后的版本的东西。我认为它应该是安全的，现在要添加调用方法，也为将来的版本中是安全的。

Right now the method does nothing, but maybe it will be doing something in future releases. I think that it should be safe to add the call to the method now and also be safe for future releases.

上任何建议？

推荐答案

它不会伤害叫的onUpdate（）这里，而且，正如你所说的，它可能有未来价值。话虽这么说，我相信有很多，很多开发商的不的调用的onUpdate（），所以如果Android的移动，使得链接到在超的onUpdate（）是非常关键的，我希望谷歌会从山顶上喊吧。

It does not hurt to call onUpdate() here, and, as you say, it may have future value. That being said, I am sure that there are many, many developers not calling onUpdate(), and so if Android shifts such that chaining to the superclass in onUpdate() is critical, I hope Google will shout it from the mountaintops.
