++ Wear 2.0 now supports inline action, which allows users to take actions on a + notification from within the notification stream card. On Wear, the inline + action appears as an additional button displayed at the bottom of the notification. +
++ Inline actions are optional but recommended for cases in which users are likely + to take an action on a notification after viewing the contents in the + notification stream card (without going to the + expanded notification). + Examples of good use cases for inline action on a notification include: replying to a + text message, stopping a fitness activity, and archiving an email message. +
+ ++ A notification can provide only one inline action. + To display the inline action as an additional button in the notification, set + the {@code setHintDisplayActionInline()} + method to true. When a user taps the inline action, the system invokes + the intent that you specified in the notification action. +
+ ++ The following code example shows how to create a notification with an inline + reply action: +
+ ++String[] choices = context.getResources().getStringArray(R.array.notification_reply_choices); + choices = WearUtil.addEmojisToCannedResponse(choices); + RemoteInput remoteInput = new RemoteInput.Builder(Intent.EXTRA_TEXT) + .setLabel(context.getString(R.string.notification_prompt_reply)) + .setChoices(choices) + .build(); ++ +
+NotificationCompat.Action.Builder actionBuilder = new NotificationCompat.Action.Builder( + R.drawable.ic_full_reply, R.string.notification_reply, replyPendingIntent); + actionBuilder.addRemoteInput(remoteInput); + actionBuilder.setAllowGeneratedReplies(true); ++
+// Android Wear 2.0 requires a hint to display the reply action inline. + Action.WearableExtender actionExtender = + new Action.WearableExtender() + .setHintLaunchesActivity(true) + .setHintDisplayActionInline(true); + wearableExtender.addAction(actionBuilder.extend(actionExtender).build()); ++
