        }

        @Override

   }

   @Override
   public void onListItemClick(ListView l, View v, int position, long id) {
Intent intent = new Intent(getApplicationContext(), Tab1Activity.class);
intent.putExtra("interestaccept_user_id",   aList.get(position).get(PRODUCT_ID));
startActivity(intent);
 }

 class LoadAlbums extends AsyncTask<String, String,   ArrayList<HashMap<String,String>>> {

@Override
protected void onPreExecute() {
    super.onPreExecute();
    pDialog = new ProgressDialog(Tab1Activity.this);
    pDialog.setMessage("Loading...");
    pDialog.setIndeterminate(true);
   // pDialog.setIndeterminateDrawable(getResources().getDrawable(R.drawable.custom_progress));
    pDialog.setCancelable(false);
    pDialog.show();
}
protected ArrayList<HashMap<String,String>> doInBackground(String... args) {
    ServiceHandler sh = new ServiceHandler();
    // Making a request to url and getting response
    ArrayList<HashMap<String,String>> data = new    ArrayList<HashMap<String, String>>();
    String jsonStr = sh.makeServiceCall(PRODUCT_URL, ServiceHandler.GET);
    Log.d("Response: ", "> " + jsonStr);
    if (jsonStr != null) {
        try {
            JSONObject jsonObj = new JSONObject(jsonStr);

            // Getting JSON Array node
            Product = jsonObj.getJSONArray(PRODUCT_DATA);

            for (int i = 0; i < Product.length(); i++) {
                JSONObject c = Product.getJSONObject(i);
                // creating new HashMap
                HashMap<String, String> map = new HashMap<String, String>();
                // adding each child node to HashMap key => value
                map.put(PRODUCT_ID, c.getString(PRODUCT_ID));
                map.put(PRODUCT_NAME,c.getString(PRODUCT_NAME));
                map.put(PRODUCT_CODE, c.getString(PRODUCT_CODE));
                map.put(PRODUCT_IMAGE, c.getString(PRODUCT_IMAGE));
                map.put(PRODUCT_WEIGHT, c.getString(PRODUCT_WEIGHT));
                map.put(PRODUCT_SALERATE, c.getString(PRODUCT_SALERATE)+getResources().getString(R.string.rupee));
               // map.put(INTEREST_ACCEPT_LOCATION, c.getString(INTEREST_ACCEPT_LOCATION));
                // adding HashList to ArrayList
                data.add(map);
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
    } else {
        Log.e("ServiceHandler", "Couldn't get any data from the url");
    }
    return data;
}
protected void onPostExecute(ArrayList<HashMap<String,String>> result) {
    super.onPostExecute(result);
    if(Product == null || Product.length() == 0){
            Toast.makeText(getApplicationContext(), "No response", Toast.LENGTH_SHORT).show();
        //noacpt.setText("  No Accepted List  ");
    }
    else
    {
        //noacpt.setVisibility(View.INVISIBLE);
    }
    // dismiss the dialog after getting all albums
    if (pDialog.isShowing())
        pDialog.dismiss();

    if(aList == null){
        aList = new ArrayList<HashMap<String, String>>();
        aList.addAll(result);
        adapter = new CustomAdapterTabone(getApplicationContext(),result);
        setListAdapter(adapter);
    }else{
        aList.addAll(result);
        adapter.notifyDataSetChanged();
    }
}

}

使用此行：

  map.put(PRODUCT_SALERATE, c.getString(PRODUCT_SALERATE)+getResources().getString(R.string.rupee));

我正在获得输出

但是我想要这样的东西

Answer 1

尝试在哈希映射中的金额之前添加卢比符号：

map.put(PRODUCT_SALERATE, getResources().getString(R.string.rupee) + c.getString(PRODUCT_SALERATE));

检查讨论后Chat

，我认为这是缺少部分
