为什么额外的数据（整数）没有在Android的通知发送的意图？ [英] Why extra data (integer) is not sent in android notification intent?

问题描述

以下code显示通知和发送int数据，但在其他活动 getExtras（）收益空。为什么呢？

  INT notificationID = 1;
NotificationManager毫微米=（NotificationManager）getSystemService（getApplicationContext（）NOTIFICATION_SERVICE）;
意图I =新意图（getApplicationContext（），DownlodResult.class）;
i.putExtra（notificationID，1）;
的PendingIntent contentIntent = PendingIntent.getActivity（getApplicationContext（），0，I，0）;
CharSequence的tickerText =有更新！
时长= System.currentTimeMillis的（）;
INT图标= R.drawable.ic_launcher;
通知通知=新的通知（图标，tickerText时）;
CharSequence的contentTitle =有更新;
CharSequence的contentText =请点击这里进行查看
notification.setLatestEventInfo（getApplicationContext（），contentTitle，contentText，contentIntent）;notification.vibrate =新长[] {100，250，100，500}; //需要震动权限
nm.notify（notificationID，通知）;
 

解决方案

也许存在的PendingIntent已经并没有创建，但重复使用。尝试与 PendingIntent.FLAG_UPDATE_CURRENT 标记创建它：

 的PendingIntent contentIntent = PendingIntent.getActivity（getApplicationContext（），0，I，PendingIntent.FLAG_UPDATE_CURRENT）;

The following code to display a notification and send int data, but in the other activity getExtras() returns null. Why?

int notificationID = 1;
NotificationManager nm = (NotificationManager) getSystemService(getApplicationContext().NOTIFICATION_SERVICE);


Intent i = new Intent(getApplicationContext(), DownlodResult.class);
i.putExtra("notificationID", 1);


PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, i, 0);


CharSequence tickerText = "There are updates !";
long when = System.currentTimeMillis();
int icon = R.drawable.ic_launcher;
Notification notification = new Notification(icon,tickerText,when);
CharSequence contentTitle = "There are updates";
CharSequence contentText = "Please click here to view it";
notification.setLatestEventInfo(getApplicationContext(), contentTitle, contentText, contentIntent);



notification.vibrate = new long[] { 100, 250, 100, 500}; // Needs vibrate permissions
nm.notify(notificationID, notification);

解决方案

Probably the PendingIntent exists already and was not created, but reused. Try to create it with the PendingIntent.FLAG_UPDATE_CURRENT flag:

PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
