java - 无法解析 setLatestEventInfo 方法

Question

我最近开发了一个应用程序，但是Android studio不再支持setLatestEventInfo方法，因此，我尝试将此方法更改为Notification.Builder方法。但是，我很挣扎，因此我希望有人支持我将此方法更改为 Notification.Builder 方法。

String ns = Context.NOTIFICATION_SERVICE;
        mNotificationManager = (NotificationManager) getSystemService(ns);

        int icon = R.drawable.ic_launcher;
        CharSequence tickerText = "Fall Detector";
        long when = System.currentTimeMillis();
        notification = new Notification(icon, tickerText, when);


        mContext = getApplicationContext();
        CharSequence contentTitle = "Fall Detector";
        CharSequence contentText = "Running";
        Intent notificationIntent = new Intent(this,StartActivity.class);
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                notificationIntent, 0);
        notification.setLatestEventInfo(mContext, contentTitle, contentText,
                contentIntent);


        mNotificationManager.notify(1, notification);

我已经尝试了以下方法，但是，它说它无法解析符号内容 Intent 。

String ns = Context.NOTIFICATION_SERVICE;
        int icon = R.drawable.ic_launcher;
        CharSequence tickerText = "Fall Detector";
        long when = System.currentTimeMillis();
        notification = new Notification(icon, tickerText, when);
        mNotificationManager = (NotificationManager) getSystemService(ns);

        Notification.Builder builder = new Notification.Builder(mContext)

                .setContentTitle("Fall Detector")
                .setContentText("Running")
                .setContentIntent(contentIntent);
        builder.build();
        Notification notification = builder.getNotification();

        mNotificationManager.notify(1, notification);

Answer 1

I have tried the below, however, it says that it cannot resolve symbol contentintent.

这是因为您未能将原始代码中的某些行复制到修改后的代码中:

    Intent notificationIntent = new Intent(this,StartActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            notificationIntent, 0);

在开始配置 Notification.Builder 之前，将这些内容添加到修订后的代码中。
