Android（以编程方式向通知添加按钮） _ANDROID

缥帙各舒散，前后互相逾。这篇文章主要讲述Android：以编程方式向通知添加按钮相关的知识，希望能为你提供帮助。
我正在尝试以编程方式将Imagebuttons添加到通知中，但我找不到工作方法。我知道这是可能的，因为我看到了similar app
这是我构建通知的方式：

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); }

以及我如何尝试添加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);

此外，看起来在创建通知后您无法添加操作，因此您应该使用指定的操作创建新通知，然后替换之前的通知（为您的通知分配ID）。
