Android：以编程方式向通知添加按钮

Question

我尝试以编程方式向通知添加Imagebuttons，但找不到此工作方法。我知道这是可能的，因为我看到similar app

这是我如何建立通知：

public class MyNotification extends Notification { 
private Context ctx; 

public Context getCtx() { 
    return ctx; 
} 

private NotificationManager mNotificationManager; 


public MyNotification(Context ctx, int layout_id) { 
    super(); 
    this.ctx = ctx; 
    String ns = Context.NOTIFICATION_SERVICE; 

    mNotificationManager = (NotificationManager) ctx.getSystemService(ns); 
    CharSequence tickerText = "Shortcuts"; 
    long when = System.currentTimeMillis(); 

    Notification.Builder builder = new Notification.Builder(ctx); 
    Notification notification = builder.getNotification(); 
    notification.when = when; 
    notification.tickerText = tickerText; 
    notification.icon = R.drawable.ic_launcher; 



    RemoteViews contentView = new RemoteViews(ctx.getPackageName(), layout_id); 



    //set button listners 
    setListeners(contentView); 

    notification.contentView = contentView; 
    notification.flags |= Notification.FLAG_ONGOING_EVENT; 
    mNotificationManager.notify(1387, notification); 

} 

，我怎么尝试添加的ImageButton

RemoteViews button = new RemoteViews(ctx.getPackageName(), R.layout.image_btn_layout_test); 


    Intent actionIntent = new Intent("MyIntent"); 
    PendingIntent pendingIntent = PendingIntent.getBroadcast(ctx, 0, actionIntent, 0); 
    button.setOnClickPendingIntent(R.id.image, pendingIntent); 

    contentView.addView(R.layout.noti_layout, button);

通过这些问题来：

此外它看起来像创建通知后不能添加操作，因此您应该创建具有指定操作的新通知，然后替换以前的通知（将id分配给您的通知）。
