Android onClick通知使用bundle将数据传递到片段

我已经使用AsyncTask实现了一个通知，我想做的是让通知在单击时传递数据。每当我点击通知时，我都会进入一个片段，该片段将获得传递的数据。我正在使用

Bundle

作为要在片段类上传递的数据。 如何将捆绑包数据传递给片段

我试着只使用Intent并删除Bundle，但它没有任何作用

new notifyThis(this, "2", "Title", "Description", "http://imgur.com/gallery/WBTdB").execute();

通知异步任务

public class notifyThis extends AsyncTask<String, Void, Bitmap> {

        private Context mContext;
        private String itemId, title, description, imageLink;
        Notification notification;
        NotificationManager notificationManager;
        DetailsFragment detailsFragment;
        FragmentManager fragmentManager;
        FragmentTransaction fragmentTransaction;
        Bundle bundle;
        PendingIntent pendingIntent;
        Intent intent;
        Resources res;

        public notifyThis(Context context, String itemId, String title, String description, String imageLink) {
            super();
            this.mContext = context;
            this.itemId = itemId;
            this.title = title;
            this.description = description;
            this.imageLink = imageLink;
        }

        @Override
        protected Bitmap doInBackground(String... params) {

            InputStream in;
            try {
                URL url = new URL(this.imageLink);
                HttpURLConnection connection = (HttpURLConnection) url.openConnection();
                connection.setDoInput(true);
                connection.connect();
                in = connection.getInputStream();
                return BitmapFactory.decodeStream(in);
            } catch (IOException e) {
                e.printStackTrace();
            }
            return null;
        }

        @Override
        protected void onPostExecute(Bitmap imageResult) {
            super.onPostExecute(imageResult);

            fragmentManager = getFragmentManager();
            fragmentTransaction = fragmentManager.beginTransaction();

            final int idItem= Integer.valueOf(itemId);

            intent = new Intent(mContext, DetailsFragment.class);

            bundle = new Bundle();
            bundle.putInt("id", idItem);

            detailsFragment= new DetailsFragment();
            detailsFragment.setTitle(title);
            detailsFragment.setArguments(bundle);
            transaction.replace(R.id.frame_container, detailsFragment);
            transaction.addToBackStack("details");
            transaction.commit();

            intent.putExtras(bundle);
            pendingIntent = PendingIntent.getActivity(mContext, 100, intent, PendingIntent.FLAG_ONE_SHOT);

            res = mContext.getResources();
            int height = (int) res.getDimension(android.R.dimen.notification_large_icon_height);
            int width = (int) res.getDimension(android.R.dimen.notification_large_icon_width);
            imageResult = Bitmap.createScaledBitmap(result, width, height, false);

            notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
            notification = new NotificationCompat.Builder(mContext)
                    .setContentIntent(pendingIntent)
                    .setContentTitle(title)
                    .setSmallIcon(R.drawable.icon)
                    .setLargeIcon(imageResult)
                    .setSubText(description)
                    .build();
            notification.flags |= Notification.FLAG_AUTO_CANCEL;
            notificationManager.notify(1, notification);
        }
}

我认为您应该在挂起的意图中使用活动，并且此活动应该在创建时将您的框架容器放在您的活动中。您可以检查数据并从中设置片段，因为这样片段与您的通知操作没有任何关系。

将数据添加到捆绑包并创建挂起的意图。将此添加到通知管理器

 Intent intent = new Intent(getActivity(), MainActivity.class);
    Bundle bundle=new Bundle();
    intent.putExtra(BUNDLE_KEY,bundle);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);

notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.mipmap.app_icon)
            .setContentTitle(title)
            .setContentText(result)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

首先，您需要使用活动从通知启动。该活动将包含要显示的片段。在片段中有一个静态初始值设定项，它将获取要传递给片段的必要参数

    /**
     * Use this factory method to create a new instance of
     * this fragment using the provided parameters.
     * @return
     */
    public static ProductFragment newInstance(String category) {
        ProductFragment fragment = new ProductFragment();
        Bundle args = new Bundle();
        args.putString(ARG_CATEGORY, category);
        fragment.setArguments(args);
        return fragment;
    }

将此方法返回的片段实例添加到活动中（使用片段管理器添加标准片段）。您可以从

onCreate

中的片段中获取参数，如下所示-

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            mCategory = getArguments().getString(ARG_CATEGORY);
        }
    }

希望这是清楚的

到底什么是“它似乎不这样工作”的意思？我还注意到你正在为一项活动准备一个悬挂式帐篷，但你的传球和意图不是一项活动。

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            mCategory = getArguments().getString(ARG_CATEGORY);
        }
    }
