android中的notificatio

先获得NotificationManager，然后通过PendingIntent 发出nofitication，在putextr里面把想通知的事情在里面说清楚，有4中notification

1、sendBasicNotification

2、sendBigTextStyleNotification

3、sendBigPictureStyleNotification

4、sendInboxStyleNotification

通过PendingIntent 回调回activity，实现了通知用户具体的事情。

public class NotificationMainActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
