Android:开发中,代码被横线划掉是什么意思

  在学习【状态栏通知】时,遇到代码被横线划掉,这是怎么回事呢?

例如:

package com.example.notification;

import android.app.Activity;
import android.app.AlertDialog;
import android.app.Notification;	
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity {
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		Button button = (Button)findViewById(R.id.button);
		button.setOnClickListener(new View.OnClickListener() {
			
			@SuppressWarnings("deprecation")
			@Override
			public void onClick(View v) {
				NotificationManager mNotificationManager = 
						(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
				int icon = android.R.drawable.sym_action_email;
				long when = System.currentTimeMillis();
				Notification notification = new Notification(icon, null, when);
				notification.defaults = Notification.DEFAULT_SOUND;
				
				PendingIntent contentIntent = PendingIntent.getActivity
						(MainActivity.this, 0, null, 0);
				
				notification.setLatestEventInfo
					(MainActivity.this, "状态栏通知测试", "上午11:02", contentIntent);
				
				mNotificationManager.notify(0, notification);
			}
		});
		
	}
}

  

  原因:这是以前使用的,现在不在使用或者已经更改,不建议使用,不过不影响程序的运行
  
  
  问题又来了,如果是更改了,改成什么了呢?我没有找到...
