使用线程运行睡眠启动来更新小部件

Question

我已经在带有主APP窗口的Android Studio中创建了一个Android小部件。这在AlarmManager上可以很好地工作，但是我将对其进行重新编码以使用具有运行，睡眠和启动功能的线程来更新小部件，但它不起作用。窗口小部件内容不会更新。

我让AlarmManager进入，被注释掉了。

import android.app.AlarmManager;
import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.Context;
import android.content.Intent;
import android.os.SystemClock;
import android.widget.RemoteViews;

public class UpdateWidget extends AppWidgetProvider {
    private PendingIntent pendingIntent;

/*
    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        final AlarmManager manager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        final Intent i = new Intent(context, UpdateService.class);

            pendingIntent = PendingIntent.getService(context, 0, i, PendingIntent.FLAG_CANCEL_CURRENT);
        manager.setRepeating(AlarmManager.ELAPSED_REALTIME, SystemClock.elapsedRealtime(), 60000, pendingIntent);

        // Onclick open the Main APP Window
        for (int appWidgetId : appWidgetIds) {
            Intent intent = new Intent(context, MainActivity.class);
            PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
            views.setOnClickPendingIntent(R.id.widget_content, pendingIntent);

            appWidgetManager.updateAppWidget(appWidgetId, views);
        }

    }

    @Override
    public void onReceive(Context context, Intent intent) {
        super.onReceive(context, intent);
    }
*/



    @Override
    public void onUpdate(final Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        super.onUpdate(context, appWidgetManager, appWidgetIds);
        final Intent i = new Intent(context, UpdateService.class);
        Thread t = new Thread() {
            @Override
            public void run() {
                try {
                    while (!isInterrupted()) {
                        Thread.sleep(100);
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {

                                PendingIntent.getService(context, 0, i, PendingIntent.FLAG_CANCEL_CURRENT);
                            }
                        });
                    }
                } catch (InterruptedException e) {
                }
            }
        };
        t.start();

        // Onclick open the Main APP Window
        for (int appWidgetId : appWidgetIds) {
            Intent intent = new Intent(context, MainActivity.class);
            PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
            views.setOnClickPendingIntent(R.id.widget_content, pendingIntent);

            appWidgetManager.updateAppWidget(appWidgetId, views);
        }

    }

    @Override
    public void onReceive(Context context, Intent i){
        super.onReceive(context, i);
    }

    private void runOnUiThread(Runnable runnable) {
    }


} // public class UpdateWidget
