Question

我制作了Reminder应用，但我无法解决方法setLatestEventInfo方法。

public class NotifyService extends Service {

    public class ServiceBinder extends Binder {
        NotifyService getService() {
            return NotifyService.this;
        }
    }

    private static final int NOTIFICATION = 123;
    public static final String INTENT_NOTIFY = "com.example.seng.healthyapp.INTENT_NOTIFY";
    private NotificationManager mNM;

    @Override
    public void onCreate() {
        Log.i("NotifyService", "onCreate()");
        mNM = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.i("LocalService", "Received start id " + startId + ": " + intent);

        if (intent.getBooleanExtra(INTENT_NOTIFY, false))
            showNotification();

        return START_NOT_STICKY;
    }

    @Override
    public IBinder onBind(Intent intent) {
        return mBinder;
    }

    private final IBinder mBinder = new ServiceBinder();

    private void showNotification() {

        CharSequence title = "Alarm!!";
        int icon = R.drawable.ic_dialog_alert;

        CharSequence text = "Your notification time is upon us.";
        long time = System.currentTimeMillis();

        Notification notification = new Notification(icon, text, time);

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

        notification.setLatestEventInfo(this, title, text, contentIntent);

        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        mNM.notify(NOTIFICATION, notification);

        stopSelf();
    }
}

修改

public class NotifyService extends Service {

    public class ServiceBinder extends Binder {
        NotifyService getService() {
            return NotifyService.this;
        }
    }

    private static final int NOTIFICATION = 123;
    public static final String INTENT_NOTIFY = "com.example.seng.healthyapp.INTENT_NOTIFY";
    private NotificationManager mNM;

    @Override
    public void onCreate() {
        Log.i("NotifyService", "onCreate()");
        mNM = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.i("LocalService", "Received start id " + startId + ": " + intent);

        if(intent.getBooleanExtra(INTENT_NOTIFY, false))
            showNotification();

        return START_NOT_STICKY;
    }

    @Override
    public IBinder onBind(Intent intent) {
        return mBinder;
    }

    private final IBinder mBinder = new ServiceBinder();

    private void showNotification() {
        CharSequence title = "Alarm!!";

        int icon = R.drawable.ic_dialog_alert;
        CharSequence text = "Your notification time is upon us.";

        long time = System.currentTimeMillis();

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

        Notification.Builder builder = new Notification.Builder(this)
                .setSmallIcon(icon)
                .setContentTitle(title)
                .setContentText(text)
                .setContentIntent(contentIntent);
        Notification notification = builder.build();

        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        mNM.notify(NOTIFICATION, notification);

        stopSelf();
    }
}

在API 23中删除了

'setLatestInfo`：https://developer.android.com/sdk/api_diff/23/changes/android.app.Notification.html

您应该使用Notification.Builder代替：https://developer.android.com/reference/android/app/Notification.Builder.html

有一个例子here。

我假设您使用的是过时的Android教程。尝试使用https://developer.android.com中的内容。他们是最可靠的。

无法解析方法`setLatestEventInfo`
