Question

我使用AlarmManager,每二次更新一次植被,但当增加更多的植被时,只更新了最后的植被。我没有说明为什么......

这是法典......

public class widget extends AppWidgetProvider {

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager,int[] appWidgetIds) {
        SharedPreferences preference = context.getSharedPreferences("MY_PREFERENCE", Context.MODE_PRIVATE);
        Intent intent = new Intent(context,vampireServiceWidget.class);
        context.startService(intent);
        for(int i=0; i<appWidgetIds.length;i++){        
            if(preference.getLong("countdown", 0)!=0){
                //Parte il countdown
                Intent in = new Intent().setAction("it.android.dev.thevampirediaries.UPDATE_COUNTDOWN");
                in.putExtra("id_widget", appWidgetIds[i]);
                in.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                PendingIntent pi = PendingIntent.getBroadcast(context, 0, in, PendingIntent.FLAG_UPDATE_CURRENT);
                AlarmManager alarm = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
                alarm.setRepeating(AlarmManager.ELAPSED_REALTIME, SystemClock.elapsedRealtime(), 1000, pi); 

                    }       }

}

- 《刑法》

    AppWidgetManager manager = AppWidgetManager.getInstance(context);
            RemoteViews remoteView = new RemoteViews(context.getPackageName(),R.layout.widgett);
         thisWidget=intent.getIntExtra("id_widget", 0)
            SimpleTimeFormat tf = new SimpleTimeFormat("$dd$ : $HH$: $mm$: $ss$");    
            String risultato = tf.format(countdown_data_fine - new Date().getTime()); // arg0 tempo
            remoteView.setTextViewText(R.id.textView1, titolo_puntata);
            remoteView.setTextViewText(R.id.textView2, risultato);
            manager.updateAppWidget(thisWidget, remoteView);

评论 lo,不寄出植被。 Use .

引言

public class widget extends AppWidgetProvider {

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager,int[] appWidgetIds) {
        SharedPreferences preference = context.getSharedPreferences("MY_PREFERENCE", Context.MODE_PRIVATE);
        Intent intent = new Intent(context,vampireServiceWidget.class);
        context.startService(intent);
        //for(int i=0; i<appWidgetIds.length;i++){        
            if(preference.getLong("countdown", 0)!=0){
                //Parte il countdown
                Intent in = new   Intent().setAction("it.android.dev.thevampirediaries.UPDATE_COUNTDOWN");
                in.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                PendingIntent pi = PendingIntent.getBroadcast(context, 0, in, PendingIntent.FLAG_UPDATE_CURRENT);
                AlarmManager alarm = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
                alarm.setRepeating(AlarmManager.ELAPSED_REALTIME, SystemClock.elapsedRealtime(), 1000, pi); 

             }
