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通知？ 请帮助我解决最简单的问题。

Answer 1

我假设您在通知栏中询问通知。如果是这样，请尝试此代码，

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. mNM.notify("Title", 0, notification); } 

Answer 2

这很简单。 在此示例中，单击按钮时会触发通知：

      public class MainActivity extends Activity { Button btn; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); btn = (Button)findViewById(R.id.button1); 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. } }); } } 

您也可以在通知中添加声音或振动。 有关更多信息，请参阅本教程。
