I am using openweathermap.org API for displaying current weather for a place user type. My application displayed it However, it is not flexible as it is displaying all different details such as weather description, latitude, longitude, Wind Speed , current temperature.. all in a single string so it is not reusable which we should make. Suppose if i want to display the place on google map with current temperature with a map marker, I should be able to get only what i want in this case current temperature and latitude and longitude.

I want these details to display on separete textfields. I am beginner in Android. Please look into my code and suggest me with a solution and guidance.

Here is my main activity code
 

Public class MainActivity extends Activity {
  Button btnSubmitCity, btnMap;
  EditText editCityText;
  TextView weather_description, current_temp, wind_speed, textViewResult;


  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    editCityText = (EditText) findViewById(R.id.editCity);
    btnMap =(Button) findViewById(R.id.mapButton);
    btnSubmitCity = (Button) findViewById(R.id.submitCity);
    weather_description = (TextView) findViewById(R.id.weatherDescription);
    current_temp = (TextView) findViewById(R.id.currentTemp);
    wind_speed = (TextView) findViewById(R.id.windSpeed);
    //textViewResult = (TextView)findViewById(R.id.result);
    textViewResult = (TextView)findViewById(R.id.result);
    btnMap.setVisibility(View.INVISIBLE);

    btnMap.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {

      }
    });
    btnSubmitCity.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        //editCityText.getText().toString();
        //HttpGetTask
        String cityString = editCityText.getText().toString();
        if(TextUtils.isEmpty(cityString)) {
          Toast.makeText(MainActivity.this, "Enter a place", Toast.LENGTH_LONG).show();
          return;
        } else{
          new HttpGetTask(cityString, weather_description).execute(cityString);

          btnMap.setVisibility(View.VISIBLE);

        }


        //String cityString = city.getText().toString();
        //new HttpGetTask().execute();
        /*
         new HttpGetTask(
            editCityText.getText().toString(),
            textViewResult).execute();
        */

      }
    });

  }
  private class HttpGetTask extends AsyncTask<String, Void, String> {
    final String FORECAST_BASE_URL = "http://api.openweathermap.org/data/2.5/weather?";
    private static final String TAG = "HttpGetTask";
    String cityName;
    TextView tvResult;

    HttpGetTask(String cityName, TextView tvResult){
      this.cityName = cityName;
      this.tvResult = tvResult;
    }


    @Override
    protected String doInBackground(String... params){
      InputStream in = null;
      HttpURLConnection httpUrlConnection = null;
      String result = "";
      try {
        Uri builtUri = Uri.parse(FORECAST_BASE_URL).buildUpon()
            .appendQueryParameter("q", cityName+",us") // city
            .appendQueryParameter("mode", "json") // json format as result
            .appendQueryParameter("units", "imperial") // metric unit
            .appendQueryParameter("APPID", "e1004b4321dde3f04591ac3386fa3a41")
            .build();
        URL url = new URL(builtUri.toString());
        httpUrlConnection = (HttpURLConnection) url.openConnection();
        in = new BufferedInputStream(
            httpUrlConnection.getInputStream());
        String data = readStream(in);
        result = edu.uco.rawal.p6rabina.JSONWeatherData.getData(data);

      } catch (MalformedURLException exception) {
        Log.e(TAG, "MalformedURLException");
      } catch (IOException exception) {
        Log.e(TAG, "IOException");
      } catch (JSONException e) {
        Log.e(TAG, e.getMessage(), e);
        e.printStackTrace();
      } finally {
        if (null != httpUrlConnection) {
          httpUrlConnection.disconnect();
        }
        if (in != null) {
          try {
            in.close();
          } catch (final IOException e) {
            Log.e(TAG, "Error closing stream", e);
          }
        }
    }

      return result;
    }
    @Override
    protected void onPostExecute(String result) {
      if (result == null || result == "") {
        Toast.makeText(MainActivity.this,
            "Invalid weather data. Possibly a wrong query",
            Toast.LENGTH_SHORT).show();
        return;
      } else {
        //btnMap.setVisibility(View.VISIBLE);
        tvResult.setText(result);

      }
     
    }

    private String readStream(InputStream in) {
      BufferedReader reader = null;
      StringBuffer data = new StringBuffer("");
      try {
        reader = new BufferedReader(new InputStreamReader(in));
        String line ;
        while ((line = reader.readLine()) != null) {
          data.append(line);
        }

      } finally {
        if (reader != null) {

            reader.close();
          } catch (IOException e) {
            e.printStackTrace();
          }
        }
      }
      return data.toString();
    }
  }
}
