在android中使用Retrofit获取null值

Question

ApiInterface

public interface ApiInterfaceTemp
 {
@GET("bf10b0f9631a80747ebfe6a674c0/37.8267,-122.4233")
Call<TempDbDailyData> getTopRatedMovies();
}

Mainactivity

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

    textView = (TextView) findViewById(R.id.temp_new);

    ApiInterfaceTemp apiInterfaceTemp = ApiClientTemp.getClient().create(ApiInterfaceTemp.class);
    Call<TempDbDailyData> call = apiInterfaceTemp.getTopRatedMovies();

    call.enqueue(new Callback<TempDbDailyData>()
    {
        @Override
        public void onResponse(Call<TempDbDailyData> call, Response<TempDbDailyData> response)
        {
            String temp = response.body().getSummary();
            textView.setText(temp);
        }

        @Override
        public void onFailure(Call<TempDbDailyData> call, Throwable t)
        {
            Log.e(TAG, t.toString());
        }
    });

}

我在这里添加了mainactivity和Api。获取变量temp的空值。请告诉我哪里出错了
