Question

从活动更新的解决方案不起作用。此代码在我的应用中无效：

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);

我在我的片段中使用此方法，以便通过单击updateButton来更新小部件。我希望这种方法可以帮助您解决问题。

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));
}

如何从片段更新小部件？
