我不能让我的按钮部件做任何事情

我刚开始学安卓,想自学语言,结果遇到了一堵砖墙。

我正在尝试编程一个非常简单的widge,它只是一个按钮。当按键按下时,手机进入静音模式。不幸的是,我能编程的唯一一件事就是弹出一条祝酒词。

有人能告诉我我的错误吗?提前谢谢你。这是我的代码:

package com.DoNotDisturb.widget;

import com.DoNotDisturb.widget.R;

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.Context;
import android.content.Intent;
import android.media.AudioManager;
import android.util.Log;
import android.widget.RemoteViews;
import android.widget.Toast;

public class DoNotDisturbWidget extends AppWidgetProvider {

    public static String ACTION_WIDGET_CONFIGURE = "ConfigureWidget";
    public static String ACTION_WIDGET_RECEIVER = "ActionReceiverWidget";

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {

        RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.main);

        Intent active = new Intent(context, DoNotDisturbWidget.class);
        active.setAction(ACTION_WIDGET_RECEIVER);

        active.putExtra("msg", "Phone is silent");

        PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);

        remoteViews.setOnClickPendingIntent(R.id.button_one, actionPendingIntent);

        appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
    }

    @Override
    public void onReceive(Context context, Intent intent) {

        // v1.5 fix that doesn't call onDelete Action
        final String action = intent.getAction();
        if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) {
            final int appWidgetId = intent.getExtras().getInt(
                    AppWidgetManager.EXTRA_APPWIDGET_ID,
                    AppWidgetManager.INVALID_APPWIDGET_ID);

            if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {
                this.onDeleted(context, new int[] { appWidgetId });
            }
        } else {
            // check, if our Action was called
            if (intent.getAction().equals(ACTION_WIDGET_RECEIVER)) {
                String msg = "null";
                try {
                    msg = intent.getStringExtra("msg");
                } catch (NullPointerException e) {
                    Log.e("Error", "msg = null");
                }
                Toast.makeText(context, msg, Toast.LENGTH_SHORT).show();

                PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intent, 0);

                NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
                Notification noty = new Notification(R.drawable.icon, "Do Not Disturb Feature Activated", System.currentTimeMillis());

                noty.setLatestEventInfo(context, "Notice", msg, contentIntent);
                notificationManager.notify(1, noty);

            } else {
                // do nothing
            }

            super.onReceive(context, intent);
        }
    }

    private AudioManager getSystemService(String audioService) {
        // TODO Auto-generated method stub
        return null;
    }
}
