Android 通过服务的通知

Question

我有一个通知系统正在工作，然后正在安排一项服务，并且通知工作正常。

我有一些通知需要用户 input/action。

这是我构建通知的代码：

public int onStartCommand(Intent intent, int flag, int startId)
{
    super.onStartCommand(intent , flag, startId);

    Uri uri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    Context context = this.getApplicationContext();
    notificationManager = (NotificationManager)context.getSystemService(context.NOTIFICATION_SERVICE);
    Intent mIntent = new Intent(this, MainActivity.class);
    pendingIntent = PendingIntent.getActivity(context, 0, mIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    Notification builder = null;
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN ) {           
        builder = new Notification.Builder(this)
                .setContentTitle(Utils.Title)
                .setContentText(Utils.Body)
                .setSmallIcon(R.drawable.ic_launcher)
                .addAction(0, Utils.button1Value, pendingIntent)
                .addAction(0, Utils.button2Value, pendingIntent)
                .setSound(uri)
                .setContentIntent(pendingIntent)
                .build();

    }

    notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
    notificationManager.notify(Utils.NotificationID, builder);     

    return START_STICKY;

我的问题是：我如何获得用户点击了通知中的哪个按钮？换句话说，如何为通知中的这 2 个操作创建某种按钮侦听器？

此外，如何堆叠我的通知，使它们不会分开显示？我在 Google API 上读到我需要使用 .setGroup，但这不起作用。 谁能分享一些通知堆叠的例子？

final static String GROUP_KEY = "myGroup"; // added String to identify the group

public int onStartCommand(Intent intent, int flag, int startId)
{
super.onStartCommand(intent , flag, startId);

Uri uri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

Context context = this.getApplicationContext();
notificationManager = (NotificationManager)context.getSystemService(context.NOTIFICATION_SERVICE);
Intent mIntent = new Intent(this, MainActivity.class);
pendingIntent = PendingIntent.getActivity(context, 0, mIntent, PendingIntent.FLAG_UPDATE_CURRENT);

Notification builder = null;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN ) {           
    builder = new Notification.Builder(this)
            .setContentTitle(Utils.Title)
            .setContentText(Utils.Body)
            .setSmallIcon(R.drawable.ic_launcher)
            .setGroup(GROUP_KEY)  // added group for Stacking
            .addAction(0, Utils.button1Value, pendingIntent)
            .addAction(0, Utils.button2Value, pendingIntent)
            .setSound(uri)
            .setContentIntent(pendingIntent)
            .build();

}

notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, builder);    // ID is always the same because the notifications are all stacking into one, tried with unique ID not working either

return START_STICKY;

按钮侦听器问题：

通知操作将触发 pendingIntent，因此只需将您的自定义意图放入其中即可。每个文本应该有一个不同的pendingIntent，这样你就可以区分它。

public int onStartCommand(Intent intent, int flag, int startId) {
    //...... 
    Intent mIntent1 = new Intent(this, MainActivity.class);
    mIntent1.setAction("clickAc1");
    PendingIntent pendingIntent1 = PendingIntent.getActivity(context, 0, mIntent1, PendingIntent.FLAG_UPDATE_CURRENT);

    Intent mIntent2 = new Intent(this, MainActivity.class);
    mIntent2.setAction("clickAc2");
    PendingIntent pendingIntent2 = PendingIntent.getActivity(context, 0, mIntent2, PendingIntent.FLAG_UPDATE_CURRENT);

    Intent it = new Intent(this, MainActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, it, PendingIntent.FLAG_UPDATE_CURRENT);

    Notification builder = null;
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN) {
        builder = new Notification.Builder(this)
                .setContentTitle("Title")
                .setContentText("Text")
                .setSmallIcon(R.drawable.your_logo)
                .addAction(0, "ac1", pendingIntent1)
                .addAction(0, "ac2", pendingIntent2)
                .setSound(uri)
                .setContentIntent(pendingIntent)
                .build();

    }

并且当用户单击文本 ac1 时，您可以在 MainActivity（或您想要的其他上下文中处理它。

//MainActivity
@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    Log.d("probe","onNewIntent:"+intent.getAction());
    //response your click event by case intent.getAction(), 
    //it will be `clickAc1` or `clickAc2`, the string you write down in intent.setAction
}

如果您使用自定义 RemoteViews，您可以按照以下步骤操作：

    Intent intent = new Intent("Your Custom intent string, like com.yourpackage.ClickButtonXXX");
    pendingIntent = PendingIntent.getService(getApplicationContext(),
        yourRequestCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    mRemoteViews.setOnClickPendingIntent(R.id.yourViewId, pendingIntent);

然后你可以用 override Service.onStartCommand(Intent intent, int flags, int startId), case intent.getAction(); 来区分不同的按钮。

堆叠消息：

我在这个 notification history article:

中找到了这个

.setGroup(GROUP_KEY_MESSAGES)  // added group for Stacking
.setGroupSummary(true)
.setContentTitle(count+" new notes")
.setStyle(new NotificationCompat.BigTextStyle().setSummaryText(count+" more"))
.build();

count++;

如果您使用 Notification，请将 NotificationCompat.BigTextStyle() 更改为 Notification.BigTextStyle()。

我想这可能就是你想要的。

汇总通知有点作弊。
