构造函数去precated [英] The constructor is deprecated

问题描述

我做一个机器人application.In我的code在我的Java类中，我得到了一些消息：构造通知（INT，CharSequence中，长期）是pcated德$ P $。一切都确定了应用程序，我没有问题，当我尝试运行应用程序。
 我只是想知道为什么这个消息被显示出来。
在我的Java类我的code是：

 公共类通知扩展活动{    @覆盖
    保护无效的onCreate（捆绑savedInstanceState）{
        // TODO自动生成方法存根
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.notifications）;        按钮B =（按钮）findViewById（R.id.bNotifications）;
        b.setOnClickListener（新View.OnClickListener（）{            @覆盖
            公共无效的onClick（视图v）{                NotificationManager纳米=（NotificationManager）getSystemService（Context.NOTIFICATION_SERVICE）;
                通知通知=新的通知（
                        android.R.drawable.stat_notify_more，
                        这是重要的，返回System.currentTimeMillis（））;
                上下文的背景下= Notifications.this;
                CharSequence的标题=您已经接到通知;
                CharSequence的细节=继续跟你做什么;
                意向意图=新的Intent（）;
                的PendingIntent未决= PendingIntent.getActivity（上下文，0，
                        意图，0）;
                notify.setLatestEventInfo（背景下，标题，细节待定）;
                nm.notify（0，通知）;            }
        }）;
    }}
 

解决方案

在看一看<一个href=\"http://developer.android.com/reference/android/app/Notification.html#Notification%28int,%20java.lang.CharSequence,%20long%29\">the文档：

  

公开的通知（INT图标，CharSequence的tickerText，时长）

  在API级别1

  
  

此构造是德$ P $在API级别11 pcated。

  使用<一个href=\"http://developer.android.com/reference/android/app/Notification.Builder.html\">Notification.Builder来代替。

据我所知，这将是相应的呼叫 Notification.Builder ：

 上下文的背景下= Notifications.this;
通知通知=新Notification.Builder（上下文）
     .setTicker（这是重要的）
     .setSmallIcon（android.R.drawable.stat_notify_more）
     .setWhen（System.currentTimeMillis的（））
     。建立（）;
 

正如你所看到的，在Notification.Builder设置各种通知性能提供了更大的灵活性，并提高code可读性，这可能是为什么通知构造是德precated的原因。

I make one android application.In my code in my java class I get some message: "The constructor Notification(int, CharSequence, long) is deprecated". Everything is ok with Application I don't have problem when I try to run the Application. I just want to know why this message is showing up. My code in my java class is:

public class Notifications extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.notifications);

        Button b = (Button) findViewById(R.id.bNotifications);
        b.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                Notification notify = new Notification(
                        android.R.drawable.stat_notify_more,
                        "This is important", System.currentTimeMillis());
                Context context = Notifications.this;
                CharSequence title = "You have been notified";
                CharSequence details = "Continue with what you have doing";
                Intent intent = new Intent();
                PendingIntent pending = PendingIntent.getActivity(context, 0,
                        intent, 0);
                notify.setLatestEventInfo(context, title, details, pending);
                nm.notify(0, notify);

            }
        });
    }

}

解决方案

Have a look at the documentation:

public Notification (int icon, CharSequence tickerText, long when)
Added in API level 1

This constructor was deprecated in API level 11.
Use Notification.Builder instead.

As far as I can tell, this would be the corresponding call to Notification.Builder:

Context context = Notifications.this;
Notification notify = new Notification.Builder(context)
     .setTicker("This is important")
     .setSmallIcon(android.R.drawable.stat_notify_more)
     .setWhen(System.currentTimeMillis())
     .build();

As you can see, Notification.Builder offers more flexibility in setting the various notification properties and improves code readability, which might be the reason why the Notification constructor was deprecated.
