Notification的使用，以及他的监听方法

public class ActivityMainNotification extends Activity {
//为Notification添加一个标识的ID.
private static int NOTIFICATIONS_ID = 1;//R.layout.activity_notification;
//为Notification添加一个管理的对象NotificationManager
private NotificationManager mNotificationManager;

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

Button button;
//使用NotificationManager的getSystemService(NOTIFICATION_SERVICE)来申明(Notification)
mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

button = (Button) findViewById(R.id.sun_1);
button.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
//这里使用了自定的方法，为了实现Notification.
setWeather("晴空万里", "天气预报", "晴空万里", R.drawable.sun);
}
});

button = (Button) findViewById(R.id.cloudy_1);
button.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
setWeather("阴云密布", "天气预报", "阴云密布", R.drawable.cloudy);
}
});

button = (Button) findViewById(R.id.rain_1);
button.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
setWeather("大雨连绵", "天气预报", "大雨连绵", R.drawable.rain);
}
});

button = (Button) findViewById(R.id.defaultSound);
button.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {

}
});

button = (Button) findViewById(R.id.defaultVibrate);
button.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {

}
});

}
});

button.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
mNotificationManager.cancel(NOTIFICATIONS_ID);
}
});

}
