title: Hashmap to JSON Array
body: <p>I would like to ask if someone here knows how to convert a HashMap to JSON Array to be used on a Adapter. The logic is when you logged in, it will fetch data on a web server using Volley, store it on SQLite database and at the same time it will show the retrieve data on a custom listview. The thing is, if you will move to another fragment on the application and then go back, it will request again on the volley which it will take time. I wanted that if you will go back the data stored on the SQLite database will be retrieved and if the user wanted to update the data using SwipeRefresh, that's the time to update for new data. </p>
  
  <p>Here is my code.</p>
  
  <pre><code>public void LoadMarkets()
  {
      Map&lt;String,String&gt;tmpRate = new HashMap&lt;String,String&gt;();
  
      RateDb db = new RateDb(getActivity().getApplicationContext());
      Cursor rs = db.getData();
      if(rs!=null &amp;&amp; rs.getCount()&gt;0)
      {
          if(rs.moveToFirst())
          {
              while(rs.moveToNext())
              {
                  tmpRate.put("rateID",rs.getString(rs.getColumnIndex(RateDb.rateID)));
                  tmpRate.put("Name",rs.getString(rs.getColumnIndex(RateDb.rateName)));
                  tmpRate.put("Rate",rs.getString(rs.getColumnIndex(RateDb.rateRate)));
                  tmpRate.put("Date",rs.getString(rs.getColumnIndex(RateDb.rateDate)));
                  tmpRate.put("Time",rs.getString(rs.getColumnIndex(RateDb.rateTime)));
                  tmpRate.put("Ask",rs.getString(rs.getColumnIndex(RateDb.rateAsk)));
                  tmpRate.put("Bid",rs.getString(rs.getColumnIndex(RateDb.rateBid)));
                  tmpRate.put("Balance",rs.getString(rs.getColumnIndex(RateDb.rateBalance)));
                  //Log.d("MyDebug",rs.getString(rs.getColumnIndex(RateDb.rateName)));
              }
          }
      }
      rs.close();
      db.close();
      JSONObject jsonObject = new JSONObject(tmpRate);
      JSONArray jsonArray = new JSONArray();
      jsonArray.put(jsonObject);
      RowAAdapter rowAAdapter = new RowAAdapter(getActivity(),jsonArray);
      lvMarkets.setAdapter(rowAAdapter);
      swipeRefreshLayout.setRefreshing(false);
  }
