進度通知未取消

Question

當我按通知中的“取消”按鈕時，通知仍保留在通知欄中，每當我按“取消”時，通知將關閉但仍顯示在頂部欄中，而當我打開通知時，通知未正確刪除。

這是創建進度通知的代碼，它可以正常工作：

private void createProgressNotification() {

    PendingIntent dismissIntent = NotificationActivity.getDismissIntent(NOTIFICATION_PROGRESS, Analyse.this);

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(context)
                    .setContentTitle("URL Analysis")
                    .setContentText("Analysis in progress")
                    .setSmallIcon(R.drawable.icon_notification)
                    .setAutoCancel(false)
                    .addAction(R.drawable.cancel, "Cancel", dismissIntent)
                    .setOngoing(true)
                    .setProgress(0, 0, true);

    NotificationManager mNotifyManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    mNotifyManager.notify(NOTIFICATION_PROGRESS, mBuilder.build());
}

這是我必須處理dismissIntent的自定義NotificationActivity類：

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, AsyncCallWS analyze) {
        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;
    }

}

知道為什么會這樣嗎？

Answer 1

在NotificationCompat Builder屬性的setAutoCancel（）中將false更改為true

  mBuilder.setAutoCancel(true);

所以會的

NotificationCompat.Builder mBuilder =
        new NotificationCompat.Builder(context)
                .setContentTitle("URL Analysis")
                .setContentText("Analysis in progress")
                .setSmallIcon(R.drawable.icon_notification)
                .setAutoCancel(true)
                .addAction(R.drawable.cancel, "Cancel", dismissIntent)
                .setOngoing(true)
                .setProgress(0, 0, true);
