android - How can I update widget from fragment? -


solutions update activity not work. code not work in app:

intent intentq = new intent(getactivity(), widget.class); intentq.setaction("android.appwidget.action.appwidget_update"); int ids[] = appwidgetmanager.getinstance(getactivity().getapplication()).getappwidgetids(new componentname(getactivity().getapplication(), widget.class)); intentq.putextra(appwidgetmanager.extra_appwidget_ids,ids); getactivity().sendbroadcast(intentq);

i use method in fragment in order update widget clicking updatebutton. hope method helps solve problem.

private void updatewidgetscreen(string updatedata) {      appwidgetmanager appwidgetmanager = appwidgetmanager.getinstance(parentactivity);     remoteviews remoteviews = new remoteviews(parentactivity.getpackagename(), r.layout.widget);     componentname thiswidget = new componentname(parentactivity, widgetprovider.class);      remoteviews.settextviewtext(r.id.remaining_money, updatedata);       intent intent = new intent(parentactivity, widgetservice.class);     intent.putextra(appwidgetmanager.extra_appwidget_id, mainutils.getwidgetid(prefs));     intent.setdata(uri.parse(intent.touri(intent.uri_intent_scheme)));     remoteviews.setremoteadapter(mainutils.getwidgetid(prefs), r.id.list_view, intent);      intent clickintent = new intent(parentactivity, mainactivity.class);     pendingintent clickpi = pendingintent.getactivity(parentactivity, 0, clickintent, pendingintent.flag_update_current);      remoteviews.setpendingintenttemplate(r.id.list_view, clickpi);     appwidgetmanager.updateappwidget(thiswidget, remoteviews);      log.e("updatewidgetscreen", updatedata+" updatedata - widgetid: "+ mainutils.getwidgetid(prefs)); }
