private void sendNotification(String msg) {
        Log.d(TAG, "Preparing to send notification...: " + msg);
        mNotificationManager = (NotificationManager) this
                .getSystemService(Context.NOTIFICATION_SERVICE);

        PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                new Intent(this, MainActivity.class), 0);

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
                this)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("GCM Notification")
                .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
                .setContentText(msg)
                .setColor(
                        getResources().getColor(
                                R.color.abc_primary_text_material_dark))
                .setVibrate(new long[] { 1000, 1000, 1000, 1000, 1000 })
                .setSound(Settings.System.DEFAULT_NOTIFICATION_URI)
                .setContentInfo("hi")
                .setTicker("hi")
                .setPriority(Notification.PRIORITY_HIGH)
                .setVisibility(Notification.VISIBILITY_PUBLIC)
                .setLights(0x0000FF, 1000, 4000)
                ;

        PowerManager pm = (PowerManager) getApplicationContext()
                .getSystemService(Context.POWER_SERVICE);
        WakeLock wakeLock = pm
                .newWakeLock(
                        (PowerManager.SCREEN_BRIGHT_WAKE_LOCK
                                | PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP),
                        "TAG");
        wakeLock.acquire(15000);
        // Settings.System.putString(getApplicationContext().getContentResolver(),
        // Settings.System.NEXT_ALARM_FORMATTED, "hi");

        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
        Log.d(TAG, "Notification sent successfully.");
    }

在您的代码中，它是通过setSmallIcon设置的图标。代码中的值R.drawable.ic_launcher是指Android项目的 res / drawable 目录中的图像。只要该图像已放置在可绘制文件夹中，您就可以将其更改为R.drawable.<name of the icon you want to use>。
