Android_通知(Notification)

通知：显示在手机的通知栏上

通知的基本用法：
1 创建一个NotificationManager 对通知进行管理

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

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

3 对通知的布局进行设定

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

4 让通知显示出来 ,第一个参数为一个任意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:            //创建通知管理器            NotificationManager notificationManager = (NotificationManager)            getSystemService(NOTIFICATION_SERVICE);            //创建通知对象            Notification notification = new Notification(R.drawable.ic_launcher, "This is ticker text",                    System.currentTimeMillis());            Intent intent = new Intent(MianActivity.this,NotificationActivity.class);            //相当于通知中的Intent，点击通知就会传送至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);            //高级功能            //声音            Uri soundUri = Uri.fromFile(new File("/system/media/audio/ringtones/nubia_mile.ogg"));            notification.sound=soundUri;            //震动            long[] vibrates = {0,1000,1000,1000};            notification.vibrate=vibrates;            //颜色            notification.ledARGB=Color.GREEN;            notification.ledOnMS=1000;            notification.ledOffMS=1000;            notification.flags=Notification.FLAG_SHOW_LIGHTS;            //默认声音led 震动 颜色效果//          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);    }}
