[英]In Android (on JB), how can I add an action to a custom rich notification?
[英]How can I create a Notification.Action and add it to a custom notification
我在這里按照谷歌的說明https://developer.android.com/training/wearables/notifications/creating.html
然而,不出所料,他們的代碼不起作用。 具體來說,我正在嘗試這樣做:
// Build the notification and add the action via WearableExtender
Notification notification =
new Notification.Builder(context)
.setSmallIcon(R.drawable.buzz_icon)
.setContentTitle("Buzz")
.setContentText("OpenBuzz")
.extend(new Notification.WearableExtender().addAction(action))
.build();
我想要一個特定於可穿戴設備的操作,所以我別無選擇,只能使用Notification.WearableExtender()
。 但它的 addAction 方法只接受一個動作作為它的參數。 這是我創建動作的代碼:
Notification.Action action =
Notification.Action.Builder(R.drawable.buzz_icon, actionIntent.toString(), pendingIntent);
哪個不起作用,因為 Android Studio 說“預期方法調用”如何成功創建Notification.Action
? 或者我還可以如何向我的通知添加可穿戴設備的特定操作?
你在正確的軌道上。
您需要創建一個新的NotificationCompat.Action.Builder
,然后在其上調用build()
。 像這樣:
NotificationCompat.Action action =
new NotificationCompat.Action.Builder(android.R.drawable.ic_menu_call, "Only in wearable", pendingIntent)
.build();
此外,請確保將操作定義為NotificationCompat.Action
,而不是Notification.Action
。
此示例說明如何添加帶有操作的通知(例如打開主活動)。
NotificationCompat.Builde mBuilder = new NotificationCompat.Builder(this, null);
Intent myIntent = new Intent(this, MainActivity.class);
PendingIntent myPendingIntent = PendingIntent.getActivity(this, 0, myIntent, 0);
mBuilder.setContentTitle("Your_title")
.setContentText("Some_text")
.setSmallIcon(R.drawable.app_icon)
.setVisibility(Notification.VISIBILITY_PUBLIC)
.setOngoing(true)
.addAction(R.drawable.open_icon, "Open", myPendingIntent)
.setAutoCancel(false);
NotificationManager mNotifyManager = (NotificationManager) getApplicationContext().getSystemService(NOTIFICATION_SERVICE);
mNotifyManager.notify(1, mBuilder.build());
