デバイスが回転したときの Android ウィジェットのコンテンツが突然なくなりました。
デバイスが回転するときにそれらを再設定する必要がありますか? しかし、ウィジェットにはリッスンする設定変更がありません。
また、alarmmanager とサービスを使用して、新しいアプリ (viewflipper に追加) のウィジェットを設定し、1 分ごとに表示しました。
ウィジェットコード:
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
try{
// create intent service per APP id
for(int i = 0; i < appWidgetIds.length; i++)
{
Log.e("onUpdate -- Widget_2_6", "onUpdate -- Widget_2_6: widget ID: " + appWidgetIds[i]);
// check if alarms not created, create 1
if(!GlobalStorage.tempStorage.containsKey(Widget_2_6.class.toString() + appWidgetIds[i]))
{
createAlarmService(context, appWidgetIds[i]);
// put to hash for alarms created
GlobalStorage.tempStorage.put(Widget_2_6.class.toString() + appWidgetIds[i], 0);
//CustomAndroidTools.popToast(Widget_2_6.class.toString() + appWidgetIds[i], context);
}
}
}
catch(Exception e)
{
Log.e("onUpdate -- Widget_2_6", "onUpdate -- Widget_2_6: error: " + e.toString());
}
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
private void createAlarmService(Context context, int id)
{
if(alarm == null)
{
createAlarm(context);
}
// each new alarm will repeat in increasing half minute: so first is 1 min next is 1 min and 30 sec ...
alarm.setRepeating(AlarmManager.RTC, 0, (1000 * (60 + (GlobalStorage.tempStorage.size() * 30))), createPendingIntent(context, id));
Log.e("createAlarmService -- Widget_2_6", "createAlarmService -- Widget_2_6, creating alarm for widget id: " + id);
}
