Java 如何在android中显示简单的通知?
如何在Android的通知栏中显示简单的通知?请帮助我找到最简单的解决方案。我猜您是在询问notificationbar中的通知。如果是这样,请尝试以下代码Java 如何在android中显示简单的通知?,java,android,Java,Android,如何在Android的通知栏中显示简单的通知?请帮助我找到最简单的解决方案。我猜您是在询问notificationbar中的通知。如果是这样,请尝试以下代码 private void showNotification(String eventtext, Context ctx) { // Set the icon, scrolling text and timestamp Notification notification = new Notification(R.draw
private void showNotification(String eventtext, Context ctx) {
// Set the icon, scrolling text and timestamp
Notification notification = new Notification(R.drawable.noti_icon,
text, System.currentTimeMillis());
// The PendingIntent to launch our activity if the user selects this
// notification
PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0,
new Intent(ctx, MainActivity.class), 0);
// Set the info for the views that show in the notification panel.
notification.setLatestEventInfo(ctx, "Title", eventtext,
contentIntent);
// Send the notification.
mNotificationManager.notify("Title", 0, notification);
}
这很容易。在本例中,单击按钮时会触发通知:

btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//We get a reference to the NotificationManager
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
String MyText = "Reminder";
Notification mNotification = new Notification(R.drawable.notification_icon, MyText, System.currentTimeMillis() );
//The three parameters are: 1. an icon, 2. a title, 3. time when the notification appears
String MyNotificationTitle = "Medicine!";
String MyNotificationText = "Don't forget to take your medicine!";
Intent MyIntent = new Intent(Intent.ACTION_VIEW);
PendingIntent StartIntent = PendingIntent.getActivity(getApplicationContext(),0,MyIntent, PendingIntent.FLAG_CANCEL_CURRENT);
//A PendingIntent will be fired when the notification is clicked. The FLAG_CANCEL_CURRENT flag cancels the pendingintent
mNotification.setLatestEventInfo(getApplicationContext(), MyNotificationTitle, MyNotificationText, StartIntent);
int NOTIFICATION_ID = 1;
notificationManager.notify(NOTIFICATION_ID , mNotification);
//We are passing the notification to the NotificationManager with a unique id.
}
});
}
}

您还可以在通知中添加声音或振动。有关更多信息,请参阅教程。是的,我看过。但它们似乎都有点混乱。我想要的只是一个简单的方法。或者?@Andromise发布您阅读过的代码,并告诉我们您在哪里感到困惑,回答这个问题的人我不理解,如果没有他的任何研究努力,您如何直接提供代码。2018检查简单的最新方法@WHK:its Notification manager尽管提到了通知构造函数不推荐使用…仍然+1…Notification.Builder()是创建通知的新方法。
