Android(安卓)实现通知栏显示多个notification

1、notifcation要显示多条，那么NotificationManager.notify( id, notify); 中的要保持不一样；

如果id值一样，那么就把之前的notify覆盖更新为当期最新的；

2、点击notification 进入到activity, 使用到pendingIntent类方法，PengdingIntent.getActivity()的第二个参数，即请求参数，

实际上是通过该参数来区别不同的Intent的，如果id相同，就会覆盖掉之前的Intent了，

只要每个不同的Intent对应传递一个独立的ID就可以，实现每个Notification点击进入对应的activity中：

Java代码

private Notification genreNotification(Context context, int icon, String tickerText, String title, String content, Intent intent, int id){
Notification notification = new Notification(icon, tickerText, System.currentTimeMillis());
// 问题就在这里的id了
PendingIntent pendIntent = PendingIntent.getActivity(context, id, intent, PendingIntent.FLAG_UPDATE_CURRENT);
// 使用了原始布局
notification.setLatestEventInfo(context, title, content, pendIntent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
return notification;
}
...
mNotificationManager.notify(ID_1,
genreNotification(mContext, ICON_RES,
notifyText1, notifyTitle1, notifyText1, intent_1, ID_1));
...
mNotificationManager.notify(ID_2,
genreNotification(mContext, ICON_RES,
notifyText2, notifyTitle2, notifyText2, intent_2, ID_2));
...
mNotificationManager.notify(ID_3,
genreNotification(mContext, ICON_RES,
notifyText3, notifyTitle3, notifyText3, intent_3, ID_3));

3、notification使用自定义布局： notification = new Notification(R.drawable.app_icon, content,
System.currentTimeMillis());
notification.defaults = Notification.DEFAULT_ALL; // 使用默认设置，比如铃声、震动、闪灯
notification.flags = Notification.FLAG_AUTO_CANCEL; // 但用户点击消息后，消息自动在通知栏自动消失
notification.flags |= Notification.FLAG_NO_CLEAR;// 点击通知栏的删除，消息不会依然不会被删除

Intent intent = new Intent(ctx, ContentNotifyActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
| Intent.FLAG_ACTIVITY_CLEAR_TOP);

intent.putExtra("content", content);
intent.putExtra("number", title);
intent.putExtra("date", date);
intent.putExtra("title", title);
RemoteViews remoteView = PushApplication.getInstance()
.getRemoteViewsView();
remoteView.setImageViewResource(R.id.notification_icon,
R.drawable.app_icon);
//标题
remoteView.setTextViewText(R.id.notification_title, title);
//内容
remoteView.setTextViewText(R.id.notification_content, content);
// 设置notification的contentView为 remoteView
notification.contentView = remoteView;

pi = PendingIntent.getActivity(ctx, NOTIFICATION_ID, intent, PendingIntent.FLAG_UPDATE_CURRENT);

// 原始样式
// notification.setLatestEventInfo(ctx, title, content, pi);

notification.contentIntent = pi;

// 将消息推送到状态栏
manager.notify(NOTIFICATION_ID++, notification);
