窗口小部件换成其他内容时，在Android的编程方式刷新 [英] Widget replaced by other content when programmatically refreshing in Android

问题描述

在这里的某个地方对堆栈溢出，我发现下面的code有一天，我调整我的应用程序了一下：

Somewhere here on Stack Overflow, I had found the following code some day which I adjusted to my application a bit:

private void updateWidget() {
    AppWidgetManager widgetManager = AppWidgetManager.getInstance(ctx);
    ComponentName widgetComponent = new ComponentName(ctx, MyAppWidgetProvider.class);
    int[] widgetIds = widgetManager.getAppWidgetIds(widgetComponent);
    Intent update = new Intent();
    update.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, widgetIds);
    update.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
    ctx.sendBroadcast(update);
}

这应该编程刷新应用程序的窗口小部件的所有实例。 CTX 是活动的上下文（这个）的我在的onCreate设置一次（）。上面的方法是所谓的活动的的onStop（）方法。

This should programmatically refresh all instances of the application's widget. ctx is the Activity's context (this) that I set once in onCreate(). The method above is called in the Activity's onStop() method.

不幸的是，当它被调用，它取代了其他应用的插件（例如AP新闻）应用程序的窗口小部件 - 至少一段时间

Unfortunately, when it is called, it replaces the app's widget by other apps' widgets (e.g. AP News) - at least for a while.

怎么能这样呢？有什么不对的code？

How can this happen? Is there something wrong in the code?

感谢您！

编辑＃1：为了更清楚地指出这一点：我已经定义了自动刷新的时间间隔。但除此之外，我想从时间更新从活动小部件时间。 这个问题的表明，这是可能的。

Edit #1: To point this out more clearly: I've already defined an interval for automatic refreshing. But in addition to that, I would like to update the widget from the Activity from time to time. This question suggests that it is possible as well.

编辑＃2：我刚刚看到了错误的部件只显示几秒钟。在那之后，我自己的应用程序的窗口小部件再次出现。

Edit #2: I've just seen that the wrong widget is only shown for some seconds. After that, my own app's widget is shown again.

推荐答案

我遇到了一些问题，在过去的窗口小部件，并解决了他们。我真的不知道为什么我的解决方案，为我工作的原因。而作为它的工作对马尔科·W·的，所以我在这里把它：我所做的感动更新code键的服务。当我需要更新，启动该服务。同样，我不知道这一点，但问题就解决了​​。

I had some problems with widgets in the past, and have solved them. I really do not know the reason why my solution worked for me. And as it worked for Marco W., so I place it here: all I did was moved the update code to a service. When I need to update, start that service. Again, I'm not sure about that but the problems were solved.

感谢马可，我得到了一些更多的经验与Android。这很有趣： - ）

Thanks Marco, I got some more experiences with Android. It's funny :-)
