import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.TextView;

import com.android.volley.toolbox.Volley;
import com.google.gson.Gson;

import org.w3c.dom.Text;

public class MainActivity extends AppCompatActivity  {

    ConnectionAPI connection = new ConnectionAPI();
    WeatherDataAPI weatherDataAPI = new WeatherDataAPI();
    TextView weatherRes;
    EditText cityName;
    String tempCityName;
    String responseString;
    WeatherDataAPI result;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        cityName=(EditText)findViewById(R.id.cityNameRow);
        weatherRes = (TextView)findViewById(R.id.weatherResult);

        connection.queue = Volley.newRequestQueue(this);

    }

    public void getWeather(View view) {

        tempCityName = String.valueOf(cityName.getText());
        connection.url = "http://api.openweathermap.org/data/2.5/weather?q="+tempCityName+"&appid=44db6a862fba0b067b1930da0d769e98";
        connection.stringRequest = new StringRequest(connection.url, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                 responseString=response;

                 Gson gson = new Gson();
                 result = gson.fromJson(responseString, WeatherDataAPI.class);

                 weatherRes.setText(result.getWeather());

            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Toast.makeText(getApplicationContext(),"Whoops Something go wrong",Toast.LENGTH_SHORT).show();
            }
        });
        connection.queue.add(connection.stringRequest);


    }
}

ConnectionAPI:

package com.example.milosz.weatherapp;

import android.content.Context;

import com.android.volley.RequestQueue;
import com.android.volley.toolbox.StringRequest;
import com.android.volley.toolbox.Volley;

/**

  */
  class ConnectionAPI {

  public RequestQueue queue;
  public String url;
  public StringRequest stringRequest;

}

WeaherDataAPI:

package com.example.milosz.weatherapp;

/**

• Created by milosz on 15.02.16.
  */
  public class WeatherDataAPI {

  private String weather;
  private String temp;

  public void setWeather(String weather){this.weather=weather;}
  public String[] getWeather()
  {
  return new String[]{weather};
  }

  public void setTemp(String temp){this.temp=temp;}
  public String[] getTemp()
  {
  return new String[]{temp};
  }

  @Override
  public String toString()
  {
  return "weather" + weather + "temp" + temp;
  }
  }

z gory dziekuje za pomoc

WeatherDataAPI result;

Nie wiem czego się spodziewałeś skoro masz tylko to przy result.

Gson gson = new Gson();
                 result = gson.fromJson(responseString, WeatherDataAPI.class);

Na dodatek pewnie model jest źle zrobiony. Nie pokazałeś JSONa
