Update TextView text size on AppWidget

Question

I can not figure this out, I\'ve been struggling with it for days now, and I\'m so tired of it..

I\'m changing the text size of a TextView on an AppWidget with a Spinne

Answer 1

So i finally got it working after trying a million different things. I ended up passing a string with the value via sharedpreferences, the same way i got the text to the widget, and just set views.setFloat(R.id.TextView, "setTextSize", Float.valueOf(SizeString)); in the widget provider it self.

Answer 2

You have to broadcast ACTION_APPWIDGET_UPDATE yourself for the first time when a configuration Activity is launched.

The Appwidgets Documentation says :

The onUpdate() method will not be called when the App Widget is created (the system will not send the ACTION_APPWIDGET_UPDATE broadcast when a configuration Activity is launched). It is the responsibility of the configuration Activity to request an update from the AppWidgetManager when the App Widget is first created. However, onUpdate() will be called for subsequent updates—it is only skipped the first time.

Update:

Try by adding this code just above the finish() line of your Config activity.

AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(this);
appWidgetManager.updateAppWidget(
        new ComponentName(this.getPackageName(), Widget.class.getName()), views);
