<div class =“post-text”itemprop =“text”> <P> 只要把这一行： </p> <pre> <code> builder.setAutoCancel(true); </code> </pre> <P> 完整的代码是： </p> <pre> <code> NotificationCompat.Builder builder = new NotificationCompat.Builder(this); builder.setSmallIcon(android.R.drawable.ic_dialog_alert); Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.google.co.in/")); PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0); builder.setContentIntent(pendingIntent); builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.misti_ic)); builder.setContentTitle("Notifications Title"); builder.setContentText("Your notification content here."); builder.setSubText("Tap to view the website."); Toast.makeText(getApplicationContext(), "The notification has been created!!", Toast.LENGTH_LONG).show(); NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); builder.setAutoCancel(true); // Will display the notification in the notification bar notificationManager.notify(1, builder.build()); </code> </pre> </DIV>

<div class =“post-text”itemprop =“text”> <P> 在使用Lollipop的Heads Up Display通知时发现这是一个问题。看到 <a href="http://developer.android.com/design/patterns/notifications.html"> 设计指南 </A> 。这是要实现的完整（ish）代码。 </p> <P> 到目前为止，拥有一个“关闭”按钮并不重要，但现在它更像是在你面前。 </p> <P> <img src =“https://i.stack.imgur.com/p4aA8.png”alt =“抬头通知”/> </p> <P> 的<strong> 建立通知 </强> </p> <pre> <code> int notificationId = new Random().nextInt(); // just use a counter in some util class... PendingIntent dismissIntent = NotificationActivity.getDismissIntent(notificationId, context); NotificationCompat.Builder builder = new NotificationCompat.Builder(context); builder.setPriority(NotificationCompat.PRIORITY_MAX) //HIGH, MAX, FULL_SCREEN and setDefaults(Notification.DEFAULT_ALL) will make it a Heads Up Display Style .setDefaults(Notification.DEFAULT_ALL) // also requires VIBRATE permission .setSmallIcon(R.drawable.ic_action_refresh) // Required! .setContentTitle("Message from test") .setContentText("message") .setAutoCancel(true) .addAction(R.drawable.ic_action_cancel, "Dismiss", dismissIntent) .addAction(R.drawable.ic_action_boom, "Action!", someOtherPendingIntent); // Gets an instance of the NotificationManager service NotificationManager notifyMgr = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); // Builds the notification and issues it. notifyMgr.notify(notificationId, builder.build()); </code> </pre> <P> 的<strong> NotificationActivity </强> </p> <pre> <code> public class NotificationActivity extends Activity { public static final String NOTIFICATION_ID = "NOTIFICATION_ID"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); manager.cancel(getIntent().getIntExtra(NOTIFICATION_ID, -1)); finish(); // since finish() is called in onCreate(), onDestroy() will be called immediately } public static PendingIntent getDismissIntent(int notificationId, Context context) { Intent intent = new Intent(context, NotificationActivity.class); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); intent.putExtra(NOTIFICATION_ID, notificationId); PendingIntent dismissIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT); return dismissIntent; } } </code> </pre> <P> 的<strong> AndroidManifest.xml中 </强> （防止SystemUI聚焦到后台堆栈所需的属性） </p> <pre> <code> <activity android:name=".NotificationActivity" android:taskAffinity="" android:excludeFromRecents="true"> </activity> </code> </pre> </DIV>

<div class =“post-text”itemprop =“text”> <P> 在新的API中不要忘记TAG： </p> <pre> <code> notify(String tag, int id, Notification notification) </code> </pre> <P> 并相应地 </p> <pre> <code> cancel(String tag, int id) </code> </pre> <P> 代替： </p> <pre> <code> cancel(int id) </code> </pre> <P> <a href="https://developer.android.com/reference/android/app/NotificationManager" rel="nofollow noreferrer"> https://developer.android.com/reference/android/app/NotificationManager </A> </p> </DIV>

至此 | 2019-08-31 10-32

<div class =“post-text”itemprop =“text”> <P> 当您在通知管理器上调用notify时，您为其指定了一个id - 这是您稍后可以用来访问它的唯一ID（来自通知管理器： </p> <pre> <code> notify(int id, Notification notification) </code> </pre> <P> 要取消，您可以致电： </p> <pre> <code> cancel(int id) </code> </pre> <P> 具有相同的ID。那么，基本上，你需要跟踪id或者可能将id放入你添加到PendingIntent里面的Intent的Bundle中？ </p> </DIV>

<div class =“post-text”itemprop =“text”> <P> 你可以随时 <code> cancel() </code> 该 <code> Notification </code> 从动作调用的任何内容（例如，在 <code> onCreate() </code> 与之相关的活动 <code> PendingIntent </code> 你供应给 <code> addAction() </code> ）。 </p> </DIV>

<div class =“post-text”itemprop =“text”> <P> 在我的使用中的意见 <code> BroadcastReceiver </code> 是一种取消通知的更简洁方法： </p> <P> 在AndroidManifest.xml中： </p> <pre> <code> <receiver android:name=.NotificationCancelReceiver" > <intent-filter android:priority="999" > <action android:name="com.example.cancel" /> </intent-filter> </receiver> </code> </pre> <P> 在java文件中： </p> <pre> <code> Intent cancel = new Intent("com.example.cancel"); PendingIntent cancelP = PendingIntent.getBroadcast(context, 0, cancel, PendingIntent.FLAG_CANCEL_CURRENT); NotificationCompat.Action actions[] = new NotificationCompat.Action[1]; NotificationCancelReceiver public class NotificationCancelReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { //Cancel your ongoing Notification }; } </code> </pre> </DIV>
