问题描述
我正在尝试动态更新小部件的TextClock的format24Hour.
I'm trying to dynamically update the format24Hour of my Widget's TextClock.
为此，我使用的是RemoteViews，如下所示:
To do so I'm using RemoteViews like so:
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.clockwidget);
views.setString(R.id.textclock, "setFormat24Hour", formatString24.toString());
appWidgetManager.updateAppWidget(appWidgetId, views);
但是，这会使我的窗口小部件显示问题加载窗口小部件"，而logcat显示
This however causes my Widget to show "Problem loading Widget" and logcat shows
03-31 17:37:19.872: W/AppWidgetHostView(1408): updateAppWidget couldn't find any view, using error view
03-31 17:37:19.872: W/AppWidgetHostView(1408): android.widget.RemoteViews$ActionException: view: android.widget.TextClock doesn't have method: setFormat24Hour(class java.lang.String)
但是，我很确定android.widget.TextClock具有标记为@RemotableViewMethod的方法setFormat24Hour(CharSequence format).
However I'm pretty sure that android.widget.TextClock has a method setFormat24Hour(CharSequence format) which is marked as @RemotableViewMethod.
有什么我想念的吗?为什么这行不通?
Is there anything I'm missing? Why isn't this working?
推荐答案
感谢njzk2，我找到了解决方案.这是一个相当愚蠢的问题.我需要调用RemoteViews#setCharSequence而不是setString，然后一切正常！
Thanks to njzk2 I found the solution. It was a rather stupid problem.I need to call RemoteViews#setCharSequence instead of setString and then everything works fine!
