java - Android 通知生成器 NoSuchMethodFound

Question

我正在尝试通过引用Notification Builder在Android推送通知中设置多个内容

代码如下:

public void onReceive(Context context, Intent intent) {
    CharSequence eventName = intent.getStringExtra("eventName");
    CharSequence eventTime = intent.getStringExtra("eventTime");
    CharSequence eventAddr = intent.getStringExtra("eventAddr");

    mNotificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    PendingIntent contentIntent = PendingIntent.getActivity(context, 1,
            new Intent(), 0);
    Notification.Builder builder = new Notification.Builder(context);
    builder.setContentIntent(contentIntent)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle(eventName)
            .setContentText(
                    "Event venue: " + eventAddr + " Event Time: "
                            + eventTime)
            .setSmallIcon(R.drawable.ic_launcher).setAutoCancel(true)
            .setWhen(System.currentTimeMillis());
    Notification notification = builder.build();
    mNotificationManager.notify(
            Integer.parseInt(intent.getExtras().get("NotifyCount")
                    .toString()), notification);
}

但我收到这些错误消息:

有任何指南吗？

提前致谢。

使用这些代码，我的通知只显示几秒钟，无需我点击它就会自动消失。有什么想法吗？

Answer 1

    NotificationCompat.Builder n;
    n=new NotificationCompat.Builder(getApplicationContext())
                    .setContentTitle("Hello")
                    .setContentText("Notification")
                    .setContentIntent(pintent)
                    .setSmallIcon(R.drawable.ic_launcher);


 NotificationCompat.InboxStyle large_content=new NotificationCompat.InboxStyle();

    large_content.setBigContentTitle("Hello content"); 

n.setStyle(inBoxStyle);

NotificationManagerCompat notificationManager =
                            NotificationManagerCompat.from(getApplicationContext());
                    notificationManager.notify(1001, n.build());

您正在使用的方法现已弃用。它不会被运行。

pintent --> 这是待处理 Intent 的对象
