单击Android通知操作不会关闭通知抽屉

我正在使用

NotificationCompat

库向系统栏添加通知。此通知有两个操作按钮。此外，通知的

AutoCancel（）

属性设置为true

单击操作按钮，系统配置为启动一个

IntentService

，该服务调用

通知管理器。取消（通知ID）

，然后在新任务中启动一个活动。
问题是，尽管此调用会从托盘中删除通知，但不会折叠抽屉。被调用的活动被绘制在抽屉后面

---

有人能告诉我们除了取消通知外，关闭抽奖还需要什么特殊代码吗？

每当您点击通知并启动活动或广播时，android系统都会为您折叠通知抽屉。我认为没有任何编程方法可以通过代码关闭通知抽屉。我建议您检查传递给NotificationBuilder的意图，并确保它们具有正确的引用意图。我认为由于您提供的意图，android通知管理器中的某些内容被阻止。到目前为止，我还没有看到通知抽屉在通知触发操作后保持打开状态。我只是想知道你的目标活动是否有一个半透明的区域，上面的活动是可见的，如果是，我建议你将背景完全不透明（没有透明/半透明区域）。这可能会阻止android home launcher完成停止序列，从而不会让launcher为您关闭通知抽屉。希望我能帮助你。祝你一切顺利。

尽管我非常感激苏米亚约蒂的回答应该是正确的。。。事实上不是

我正在使用

Intent CR = new Intent(CRCODE); 
PendingIntent.getBroadcast(getApplicationContext(), MY_ID, CR, 0);

在正在进行的通知的remoteview布局中

我可以向您保证，它不会关闭抽屉，但会激发意图并在打开的抽屉后面绘制活动，以及执行我分配给接收者的其他任务

我已经测试了getActivity和getService（在我的情况下两者都不起作用，我需要在接收时激发多个意图），它们都正确地关闭了抽屉

我知道这不是一个答案，但当我找到它，我会报告回来编辑这个

疯狂的想法。。。也许一个没有内容视图的活动可以被称为广播接收器，根据需要向其他类或应用程序发送适当的意图

---

上面列出的疯狂想法有效。。。使用PendingEvent.getActivity启动一个活动，并将其用于转播广播或其他意图，然后自行完成。。。这种效果不是直接的，但最终用户无法察觉

我发现，当您在扩展通知中使用操作按钮时，您必须编写额外的代码，而且您受到的约束更大

在使用扩展通知之前，我的文件下载通知中的默认操作是启动文件的查看活动。视图意图由选择器意图包装。我无法直接从通知中为选择器意图使用挂起的意图，因为如果没有查看文件类型的活动，选择器将崩溃。所以我有一个广播接收器，可以启动选择器意图

对于扩展通知，我决定更改文件下载通知，因此默认操作是显示文件详细信息活动，并带有查看和发送操作按钮。如user2536953所述，从通知启动广播接收器不会关闭通知抽屉。根据他的信息，某个活动将关闭抽屉，我将广播接收器更改为没有任何UI的NotificationActivity

正如本文所指出的，另一个问题是，当用户单击操作按钮时，您必须手动取消通知。只有默认操作才会自动取消通知。我还在NotificationActivity中添加了代码来处理这个问题

使用查看和发送按钮生成扩展通知：

    NotificationCompat.Builder builder = new NotificationCompat.Builder(m_context).setAutoCancel(true);

    final PendingIntent contentIntent = DownloadedFileIntentUtils.buildPendingItemDetailIntent(m_context, item);
        builder.setContentIntent(contentIntent);

    PendingIntent viewIntent = DownloadedFileIntentUtils.buildNotificationActionIntent(m_context, Intent.ACTION_VIEW,
                m_context.getString(R.string.action_open), uri, MimeTypeUtil.getMimeType(item), id);
    builder.addAction(R.drawable.actionbar_open_with, m_context.getString(R.string.action_open), viewIntent);

    PendingIntent sendIntent = DownloadedFileIntentUtils.buildNotificationActionIntent(m_context, Intent.ACTION_SEND,
                m_context.getString(R.string.action_send), uri, MimeTypeUtil.getMimeType(item), id);
    builder.addAction(R.drawable.actionbar_share, m_context.getString(R.string.action_send), sendIntent);

    builder.setTicker(title)
    .setContentTitle(title)
    .setContentText(text)
    .setSmallIcon(R.drawable.notification_download);
    .setStyle(new NotificationCompat.BigTextStyle().bigText(text));

    getNotificationManager().notify(id, builder.build());

    public static PendingIntent buildNotificationActionIntent(Context context, String action, String actionTitle, Uri uri,
        String mimeType, int notificationId) {
    // Build the file action intent (e.g. VIEW or SEND) that we eventually want to start.
    final Intent fileIntent = buildFileActionIntent(action, actionTitle, uri, mimeType);

    // Build the intent to start the NotificationActivity.
    final Intent notificationIntent = new Intent(context, NotificationActivity.class);
    // This flag must be set on activities started from a notification.
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    // Pass the file action and notification id to the NotificationActivity.
    notificationIntent.putExtra(Intent.EXTRA_INTENT, fileIntent);
    notificationIntent.putExtra(IIntentCode.INTENT_EXTRA_NOTIFICATION_ID, notificationId);

    // Return a pending intent to pass to the notification manager.
    return PendingIntent.getActivity(context, s_intentCode.getAndIncrement(), notificationIntent, PendingIntent.FLAG_ONE_SHOT);
}

public static Intent buildFileActionIntent(String action, String actionTitle, 
        Uri uri, String mimeType) {
    Intent intent = new Intent(action);
    intent.addCategory(Intent.CATEGORY_DEFAULT);

    if (action.equals(Intent.ACTION_SEND)) {
        intent.putExtra(Intent.EXTRA_STREAM, uri);
        intent.setType(mimeType);
    } else {
        intent.setDataAndType(uri, mimeType);
    }

    intent.putExtra(Intent.EXTRA_TITLE, actionTitle);

    // Grant read permission on the file to other apps without declared permission.
    int flags = Intent.FLAG_GRANT_READ_URI_PERMISSION;
    intent.setFlags(flags);

    return intent;
}

public class NotificationActivity extends Activity {
private final static Logger s_logger = LogUtil.getLogger(NotificationActivity.class);

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Intent intent = getIntent();

    // Cancel the notification that initiated this activity.
    // This is required when using the action buttons in expanded notifications.
    // While the default action automatically closes the notification, the
    // actions initiated by buttons do not.
    int notificationId = intent.getIntExtra(IIntentCode.INTENT_EXTRA_NOTIFICATION_ID, -1);
    if (notificationId != -1) {
        NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        manager.cancel(notificationId);
    }

    // If there is an activity to handle the action, start the file action.
    if (DownloadedFileIntentUtils.verifyActivityIsAvailable(this, fileActionIntent, false)) {
            fileActionIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            DownloadedFileIntentUtils.startFileActionActivity(this, fileActionIntent);
    }

    // Finish activity.
    finish();
}

public static void startFileActionActivity(Context context, Intent fileActionIntent) {
    // Start chooser intent.
    Intent chooser = Intent.createChooser(fileActionIntent, fileActionIntent.getStringExtra(Intent.EXTRA_TITLE));

    // Copy the flags from fileActionIntent to chooser intent.
    // FileActionExecutor must set FLAG_ACTIVITY_NEW_TASK on the intent passed to startActivity
    // because the flag is required when starting an activity from a context that is not an activity.
    chooser.addFlags(fileActionIntent.getFlags());

    context.startActivity(chooser);
}

从通知操作按钮构建启动活动的意图：

不要忘记将NotificationActivity添加到AndroidManifest.xml

如果您的操作是以广播或服务的形式进行的，但您打算让通知抽屉崩溃，那么您应该从onReceive广播android.intent.action.CLOSE\u SYSTEM\u对话框。这将手动关闭抽屉。

尝试以下操作：

    NotificationManager notificationManager = (NotificationManager) getApplicationContext().getSystemService(getApplicationContext().NOTIFICATION_SERVICE);
    Intent notificationIntent = new Intent(this.getBaseContext(), MainActivity.class);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    NotificationCompat.Builder mNotifyBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(
            getApplicationContext())
            .setTicker(getApplicationContext().getText(R.string.app_name))
            .setContentTitle(getApplicationContext().getText(R.string.app_name))
            .setContentText(getApplicationContext().getText(R.string.text))
            .setSmallIcon(R.drawable.smallicon)
            .setLargeIcon(BitmapFactory.decodeResource(getApplicationContext().getResources(), R.mipmap.ic_launcher))
            .setContentIntent(pendingIntent)
            .setAutoCancel(true)
            .setVibrate(new long[]{150, 300});
    mNotifyBuilder.build().flags |= Notification.FLAG_AUTO_CANCEL;
    notificationManager.notify(1, mNotifyBuilder.build());

你找到解决办法了吗？没有。只是一些黑客使用反射和扩展，折叠状态栏。显然，如果挂起的意图包含解析为活动的意图，则抽屉将自动折叠。但是，如果您的挂起意图包装了BroadcastReceiver或服务，则通知栏将保留其（扩展）状态。我需要在NotificationActivity中设置android:taskAffinity=“”，否则它也将启动Main活动如果它存在于backstack中，请我有问题SendBroadcast（新意图（Intent.ACTION\u CLOSE\u SYSTEM\u DIALOGS））；可以在上下文对象中找到sendBroadcast方法。在调用上下文之前，我在BroadcastReceiver中添加了这几行。startActivity（myIntent）Intent it=新的Intent（Intent.ACTION\u CLOSE\u SYSTEM\u DIALOGS）；context.sendBroadcast（it）；解决方案工作正常，但无法理解为什么我们需要发送操作_关闭_系统_对话框广播。这似乎与提醒通知没有任何区别
