在Android中创建通知应用程序？ [英] Create Notification App in Android?

问题描述

我想创建一个示例项目上显示按钮，然后在用户选择它在我的应用程序打开该活动或打开that.I选择一个网址的点击通知做了一些事，但我没能完成功能。

I want to create a sample project to show notification on click of button then when the user selects it open that activity in my app or open a url on selection of that.I have done something but i am not able to complete the functionality .

首先我得到使用这个错误的 @燮pressLint（NewApi）

First i am getting error to use this @SuppressLint("NewApi")

如果我不使用此我得到有关这里的误差

If i am not using this i am getting the error on here

Notification noti = new Notification.Builder(this)

活动code

public class NotificationExample extends Activity implements OnClickListener{

    private Button b;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_notification_example);
        b=(Button)findViewById(R.id.button1);
        b.setOnClickListener(this);

    }


    @SuppressLint("NewApi")
    @Override
    public void onClick(View v) {
        Intent intent = new Intent();
        PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);
        Notification noti = new Notification.Builder(this)
        .setTicker("Ticker Title")
        .setContentTitle("Content Title")
        .setContentText("Notification content.")
        .setSmallIcon(R.drawable.ic_launcher)
        .setContentIntent(pIntent).getNotification();
        noti.flags=Notification.FLAG_AUTO_CANCEL;
        NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        notificationManager.notify(0, noti); 
    }
}

为什么我必须使用这样的：

why i have to use this :

`@SuppressLint("NewApi")` 

在我的code。
我没有得到通知sound.Please建议我什么样的变化，我有我的code键使。

in my code . I am not getting the notification sound.Please suggest me what changes i have to make in my code.

推荐答案

要声音添加到您的通知，请使用以下简称code的。

To add sound to your notification, use following short of code.

Uri notificationSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
builder.setSound(notificationSound);

展开code

PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent,
                0);
Builder builder = new NotificationCompat.Builder(context)
                .setTicker("Ticker Title").setContentTitle("Content Title")
                .setContentText("Notification content.")
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentIntent(pIntent);
Uri notificationSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
builder.setSound(notificationSound);
Notification noti = builder.build();
noti.flags = Notification.FLAG_AUTO_CANCEL;
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, noti);

背景是应用程序上下文获得使用 getApplicationContext（）。

修改

要使用通知，请使用以下code打开任何链接到浏览器中。

To open any link to Browser using Notification, use following code.

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("http://www.google.com"));

通过这个意图，你的的PendingIntent
