Android Retrofit GET

Question

私はRetrofitを初めて使用しており、これを使用して簡単なアプリを構築しました。しかし、私はアプリを実行しようとすると、それはWebからフェッチされたデータを表示しませんでした。しかし、apiヒットは毎回増加しています。親切に私がこれを解決するのを手伝ってください。 ありがとうございます。

    this.daycode = daycode; 
} 

public String getRuns() { 
    return runs; 
} 

public void setRuns(String runs) { 
    this.runs = runs; 
} 

public String getDaycode() { 
    return daycode; 
} 

public void setDaycode(String daycode) { 
    this.daycode = daycode; 
} 
} 

いくつかの他はありませんしながら、なぜ唯一のいくつかのゲッターとセッターがオレンジ色に着色されていますか？

また、アプリがクラッシュしていないのに、logcatに2つの問題が見つかりました。 Logcat：
