问题 I'm following this post to create nine patch drawable at run-time. I need to save the 9patch image on the internal/external memory, so that i can easily retrieve it's URI and assign it to an ImageView for example. Does anybody know how can I achieve this? P.S. Bitmap.compress method won't work, because it will save the image as a regular (not 9patch) png file. P.S. I know that I can serialize generated NinePatch object and save it to a file. But this way I can't assign it to a RemoteViews

问题 So I'm seeing some bizarre behavior in an appwidget that I wrote. The widget itself is quite simple - it reads a few values from persistent storage and then displays them as text. Nothing fancy in the layout - just a FrameLayout root element with some Linear Layout and TextView children. The widget has a simple configuration activity associated with it. The bizarre behavior is that the widget will initially show "Problem Loading Widget" after the user closes the configuration activity, and

问题 Can anyone help me on how to handle orientation change for app widget? On orientation change my widget is showing layout with empty view and removing all listeners. 回答1: After research and studying some of the folks answers , I came to know the mistake i have done. After initial setup of the widget , I am again initializing remote views and trying to change only few views like when user taps on refresh button , iam making that view visibility gone and making circular progress loading view

问题 When I'm adding single widget I can configure it properly and it's updated as supposed to after initial configuration. But when I add second and next instances of widget with the same or different configuration onUpdate is not triggered. Well, to be specific onUpdate is executed just before Configuration is set, when Configuration Activity is on top, so it works like: 1 widget - OK 2 widgets - First OK, Second not updated 3 widgets - First OK, Second OK, Third not updated and so on. Behavior

问题 I wanted to display a progress bar in an appwidget that displays playback progress from a background service. I know the appwidget supports that control, but I am wondering how I might go about updating the progress bar in a way that is consistent with good widget design (e.g. low battery consumption). The way I would normally do it in an activity would be by polling the playback on a timer. I haven't implemented this yet, so I am not even sure if it would work in an appwidget. Anyone know

问题 I've this homescreen widget: It's easy to update for example two buttons next to the logo from activity , because I have their appWidgetIds from onUpdate method from AppWidgetProvider , but imagebuttons in the list are created in RemoteViewsFactory class in getViewAt() method. @Override public RemoteViews getViewAt(int position) { RemoteViews row = new RemoteViews(ctxt.getPackageName(), R.layout.list_row_widget); row.setTextViewText(R.id.tvDescription, items.get(position).name); Intent i =

问题 I'm creating a fairly common use case of AppWidget on Android. AppWidgetProvider calls onAppWidgetOptionsChanged() (stretchable widget) and onUpdate() (timed) From those methods I start an IntentService . Case coming from options changed I pass the new size in the Intent. The service contacts a web-service, builds the RemoteViews and calls updateAppWidget() my main test device is a Nexus 7 (2012) running stock 4.3 (stock Launcher) The widget does not use RemoteViewFactory and does not user
