如何使用Arraylist中的bundle使用putserializable获取传递的值 <Hashmap<String,String> &gt;

Question

I created a list using the following, which gets the value from model class which has getter and setter.

    int k = model.getChildren().size();
    for(int i=0;i < k;i++) {
        HashMap<String, String> map = new HashMap<String, String>();
        galleryChildModel = model.getChildren().get(i);
        map.put("caption", galleryChildModel.getImagecaption());
        map.put("imageurl", galleryChildModel.getImageurl());
        list.add(map);
    }

then im passing this value to next fragment using this setOnItemClickListener

       gridchild.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Fragment fragment = new GalleryDetailFragment();
            Bundle bundle = new Bundle();
            bundle.putSerializable("object", list.get(position));
            fragment.setArguments(bundle);
            FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
            fragmentTransaction.replace(R.id.container_body, fragment);
            fragmentTransaction.addToBackStack(null);
            fragmentTransaction.commit();
        }
    });

i'm getting the value in the respective fragment using

   Bundle bundle = this.getArguments();

    if (bundle != null) {
          ArrayList<HashMap<String, String>> maps = (ArrayList<HashMap<String, String>>) bundle.get("object"); // here i cannot cast the value to hashmap or any list. im really stuck here can anyone help me out with this
    }

the value im getting is like this

Bundle[{ object=[{ imageurl= http://futhead.cursecdn.com/static/img/15/players/20801.png,caption=Ronaldo .}]}]

how to get data from this and set to a textview and imageview....

Answer 1

bundle.putSerializable("object", list.get(position));

存储在“对象”下的Serializable是HashMap而不是List，因此您应将其强制转换为Hashmap：

HashMap<String,String> map = (HashMap<String, String>) bundle.getSerializable("object");
