Android_通知(Notification)

通知：顯示在手機的通知欄上

通知的基本用法：
1 創建一個NotificationManager 對通知進行管理

NotificationManager manager =
(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);

2 創建Notification
Notification notification = new NOtification
(R.drawable.icon,”This is tiket text”,System.currentTimeMills());

3 對通知的佈局進行設定

notification.
setLatestEventInfo(context,”This is Title”,”This is content”,null);

4 讓通知顯示出來 ,第一個參數爲一個任意id
manager.notify(1,notification);

案例：
    public class MianActivity extends Activity implements OnClickListener{
    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button sendNotice = (Button)findViewById(R.id.send_button);

        sendNotice.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        switch(v.getId()){

        case R.id.send_button:
            //創建通知管理器
            NotificationManager notificationManager = (NotificationManager)
            getSystemService(NOTIFICATION_SERVICE);

            //創建通知對象
            Notification notification = new Notification(R.drawable.ic_launcher, "This is ticker text",
                    System.currentTimeMillis());

            Intent intent = new Intent(MianActivity.this,NotificationActivity.class);

            //相當於通知中的Intent，點擊通知就會傳送至NotificationActivity.class
            PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 
                    PendingIntent.FLAG_CANCEL_CURRENT);

            notification.setLatestEventInfo(this, "This is the Title", "This is the Text", pendingIntent);


            //高級功能
            //聲音
            Uri soundUri = Uri.fromFile(new File("/system/media/audio/ringtones/nubia_mile.ogg"));

            notification.sound=soundUri;

            //震動
            long[] vibrates = {0,1000,1000,1000};
            notification.vibrate=vibrates;

            //顏色
            notification.ledARGB=Color.GREEN;
            notification.ledOnMS=1000;
            notification.ledOffMS=1000;
            notification.flags=Notification.FLAG_SHOW_LIGHTS;

            //默認聲音led 震動 顏色效果
//          notification.defaults=Notification.DEFAULT_ALL;

            notificationManager.notify(1,notification);
            break;
            default:
                break;


        }
    }
}

    public class NotificationActivity extends Activity {
    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.notification_layout);

        NotificationManager notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);

        notificationManager.cancel(1);
        //notificationManager.notify(1,notification);
    }
}
