遇到的最大的问题是监听不到用户清除通知栏的广播。因此是不能监听到的。java
自定义通知栏的View，而后service运行时更改notification的信息。app
/**
* Show a notification while this service is running.
* 在service运行时，显示通知信息
*/
public void showNotification() {
NotificationManager mNM = (NotificationManager)getSystemService(NOTIFICATION_SERVICE); CharSequence text = getText(R.string.app_name);
Notification notification = new Notification(R.drawable.img_step_counter_user, null,
System.currentTimeMillis());
// 标志位的设置：应设置为能够自动取消，这样用户就能够取消他，若是设置为Intent.FLAG_ACTIVITY_CLEAR_TOP | Notification.FLAG_ONGOING_EVENT;则会一直显示通知// notification.flags = Intent.FLAG_ACTIVITY_CLEAR_TOP | Notification.FLAG_ONGOING_EVENT;
notification.flags = Notification.FLAG_AUTO_CANCEL;
Intent pedometerIntent = new Intent();
pedometerIntent.setComponent(new ComponentName(this, StepCounterHomePageActivity.class));
pedometerIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
pedometerIntent, 0);
notification.setLatestEventInfo(this, text,
getText(R.string.notification_subtitle)+": "+SensorData.stepNum+" 步", contentIntent);
// 其中R.layout.notification是一个布局文件 notification.contentView = new RemoteViews(getPackageName(),R.layout.notification);
notification.contentView.setViewVisibility(R.id.usermessage, View.VISIBLE);
notification.contentView.setViewVisibility(R.id.notification_background, View.GONE);
notification.contentView.setViewVisibility(R.id.notification_layout, View.GONE);
notification.contentView.setTextViewText(R.id.tv_user_name_step, "掌上医生");
notification.contentView.setTextViewText(R.id.tv_use_date_step, "计算步数： "+SensorData.stepNum+"步");
mNM.notify(R.string.app_name, notification);
}
