Android - 无法在通知栏中显示操作

Question

我正在开发 Android 中的可操作通知。

void createActionableNotification() {
    Intent intent = new Intent(this, MainActivity.class);
    PendingIntent pIntent = PendingIntent.getActivity(this, (int) System.currentTimeMillis(), intent, 0);

    // Build notification
    // Actions are just fake
    Notification noti = new NotificationCompat.Builder(this)
            .setContentTitle("New mail from " + "test@gmail.com")
            .setContentText("Subject").setSmallIcon(R.drawable.moneybag)
            .setContentIntent(pIntent)
            .addAction(R.drawable.moneybag, "Call", pIntent)
            .addAction(R.drawable.moneybag, "More", pIntent)
            .addAction(R.drawable.moneybag, "And more", pIntent).build();
    NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    // hide the notification after its selected

    noti.flags |= Notification.FLAG_AUTO_CANCEL;

    notificationManager.notify(0, noti);
}

所以它显示像这样的操作，请检查下面的图片。

应用程序正在使用目标 SDK 运行，编译 SDK API 为 24，Min SDK 为 20。 我用 Marshmallow Device 进行了测试。但在模拟器中它工作正常。模拟器 SDK 版本为 24

Answer 1

试试这个：适用于 api >= 16

 Notification notification = new Notification.Builder(myContext)
.setContentTitle("New mail from " + "test@gmail.com")
            .setContentText("Subject").setSmallIcon(R.drawable.moneybag)
            .setContentIntent(pIntent)
            .setPriority(Notification.PRIORITY_MAX)
            .addAction(R.drawable.moneybag, "Call", pIntent)
            .addAction(R.drawable.moneybag, "More", pIntent)
            .addAction(R.drawable.moneybag, "And more", pIntent).build();

//The rest of your options
.build();

当列表中有任何 Ongoing Notification 时，按钮不会出现，例如媒体播放器控件，或者您通过 USB 将手机连接到 PC 或在编辑文本时...

你可以尝试Notification.PRIORITY_MAX 来解决这个问题，或者PRIORITY_HIGH
