紛らわしいタイトルで申し訳ありません(私の問題を短い言葉で説明する理由はありません)

これは私の状況です:

私は2つのJSONArrayを含むJSONを持っているスタンプを収集 するアプリ開発います "collectedStamp""unCollectedStamp" "arraylistCollected""arraylistUncollected"

また、収集済みおよび収集のすべてのスタンプを表示するためのGridViewが1 つあります。

そのため、これらの2 つの ArrayListを配置するListViewAdapter には、両方を組み合わせて"arraylistCollected"、名前付きの1つの Arraylist"arraylistUncollected"にする必要がありました"arraylistCombined"

すべてのスタンプが 1 つの GridView で正しく表示されるようになりましたが、収集されたスタンプと収集されていないスタンプを検出して、魔女スタンプ収集されたかどうかをユーザーが認識できるようにしたいと考えています。たとえば、集めたスタンプをカラフルに、未収集のスタンプを黒と白に、または

"arraylistCollected"これら2つの配列の要素を検出する方法がわからない"arraylistUncollected" ので、後でそれらの画像を使って何でもできます。

この問題を解決するためのあなたの意見やアイデアは何ですか?

この JSON 結果

{
    "status": "1",
    "tappedStamp": "15",
    "message": "stamp message",
    "stampimage": "stamp3.png",
    "stampname": "stamp3",
    "collectedStamp": [
        {
            "id": "14",
            "stampname": "stamp2 ",
            "message": "stamp2 message",
            "stampimage": "stamp2.png"
        },
        {
            "id": "15",
            "stampname": "stamp3",
            "message": "stamp message",
            "stampimage": "stamp3.png"
        }
    ],
    "unCollectedStamp": [
        {
            "id": "12",
            "stampname": "Testing MKH Stamp",
            "message": "Testing MKH Stamp",
            "stampimage": "award.png"
        },
        {
            "id": "13",
            "stampname": "stamp1",
            "message": "stamp1 Message",
            "stampimage": "stamp1.png"
        },
        {
            "id": "16",
            "stampname": "Testing MKH Stamp",
            "message": "Testing MKH Stamp",
            "stampimage": "award.png"
        }
    ]
}

これはJSONをダウンロードするためのコードです

        @Override
        protected Void doInBackground(Void... params) {
            // Create an array
            arraylistCollected = new ArrayList<HashMap<String, String>>();
            arraylistUncollected = new ArrayList<HashMap<String, String>>();



            this.sharedPref = getSharedPreferences(getString(R.string.key_storage),0);

            try {
                // building parameters for Logout
                List<NameValuePair> param = new ArrayList<NameValuePair>();
                param.add(new BasicNameValuePair(TAG_ACCESSTOKEN, accesstoken));
                param.add(new BasicNameValuePair(TAG_KIOSK_ID, kioskid));
                Log.d("request!", "Starting");


            // Retrieve JSON Objects from the given URL address
            jsonobject = JSONParser.makeHttpRequest(STAMPS_LIST_URL,"POST",param);
            Log.d("Loding Stamps Attemp", jsonobject.toString());

            // get tapped Stamp Image Url 
            tappedStampImageUrl = jsonobject.getString(TAG_STAMP_IMAGE);

            // Locate UNCOLLECTED STAMPS array name in JSON
            jsonArrayUncollected = jsonobject.getJSONArray(TAG_UNCOLLECTED_STAMPS);

            for (int i = 0; i < jsonArrayUncollected.length(); i++) {
                HashMap<String, String> map = new HashMap<String, String>();
                JSONObject jsonobject = jsonArrayUncollected.getJSONObject(i);

                // Retrive JSON Objects
                map.put(TAG_STAMPS_ID, jsonobject.getString(TAG_STAMPS_ID));

                map.put(TAG_STAMP_NAME, jsonobject.getString(TAG_STAMP_NAME));
                map.put(TAG_MESSAGE, jsonobject.getString(TAG_MESSAGE));
                // Set the JSON Objects into the array
                arraylistUncollected.add(map);
            }
Log.d("jsonArrayUncollected Size:", ""+arraylistUncollected.size());


            // Locate COLLECTED STAMPS array name in JSON
            jsonArrayCollected = jsonobject.getJSONArray(TAG_COLLECTED_STAMPS);

            for (int i = 0; i < jsonArrayCollected.length(); i++) {
                HashMap<String, String> map = new HashMap<String, String>();
                JSONObject jsonobject = jsonArrayCollected.getJSONObject(i);

                // Retrive JSON Objects
                map.put(TAG_STAMPS_ID, jsonobject.getString(TAG_STAMPS_ID));
                map.put(TAG_STAMP_IMAGE, jsonobject.getString(TAG_STAMP_IMAGE));

                map.put(TAG_MESSAGE, jsonobject.getString(TAG_MESSAGE));

                // Set the JSON Objects into the array
                arraylistCollected.add(map);
            }
            Log.d("jsonArrayCollected Size:", ""+arraylistCollected.size());


                arraylistCombined = new ArrayList<HashMap<String, String>>();
                arraylistCombined.addAll(arraylistCollected);
                arraylistCombined.addAll(arraylistUncollected);

                Log.d("arraylistCombined Size:", ""+arraylistCombined.size());


            } catch (JSONException e) {
                Log.e("Error", e.getMessage());
                e.printStackTrace();
            }
            return null;
        }

    @Override
            protected void onPostExecute(Void args) {

                imageLoader.DisplayImage(TAG_IMAGE_URL+tappedStampImageUrl, tappedStampImage);
                Animation myFadeInAnimation = AnimationUtils.loadAnimation(StampsActivity.this, R.anim.fadein);
                tappedStampImage.startAnimation(myFadeInAnimation);
                // Locate the listview in listview_main.xml
                //listview = (ListView) findViewById(R.id.listview);
                gridView = (GridView) findViewById(R.id.gridView1);

                // Pass the results into ListViewAdapter.java
                adapter = new ListViewAdapter(StampsActivity.this, arraylistCombined);

                // Set the adapter to the ListView
                //listview.setAdapter(adapter);
                gridView.setAdapter(adapter);
                // Close the progressdialog
                mProgressDialog.dismiss();
            }
        }

これはListViewAdapterです

public class ListViewAdapter extends BaseAdapter {

    // Declare Variables
    Context context;
    LayoutInflater inflater;
    ArrayList<HashMap<String, String>> data;
    ImageLoader imageLoader;
    HashMap<String, String> resultp = new HashMap<String, String>();

    public ListViewAdapter(Context context,
            ArrayList<HashMap<String, String>> arraylist) {
        this.context = context;
        data = arraylist;
        imageLoader = new ImageLoader(context);
    }

    @Override
    public int getCount() {
        return data.size();
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    public View getView(final int position, View convertView, ViewGroup parent) {
        // Declare Variables

        TextView tvStampName;
        ImageView stampImage;

        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View itemView = inflater.inflate(R.layout.single_stamp_layout, parent, false);
        // Get the position
        resultp = data.get(position);

        tvStampName = (TextView) itemView.findViewById(R.id.tvStampName);
        stampImage = (ImageView) itemView.findViewById(R.id.stampImage);

        tvStampName.setText(resultp.get(StampsActivity.TAG_STAMP_NAME));

        // Passes stampImage images URL into ImageLoader.class
        imageLoader.DisplayImage(TAG_STAMP_IMAGE_URL+resultp.get(StampsActivity.TAG_STAMP_IMAGE), stampImage);
        Animation myFadeInAnimation = AnimationUtils.loadAnimation(context, R.anim.fadein);
        stampImage.startAnimation(myFadeInAnimation);
        return itemView;
    }
}
