安卓：無法採取API響應到ArrayList中

我正在按照上面的錯誤是我的代碼和日誌貓安卓：無法採取API響應到ArrayList中

public class TimeMain { 
String name; 

public ArrayList<Lecture> getLectures() { 
    return lectures; 
} 

public void setLectures(ArrayList<Lecture> lectures) { 
    this.lectures = lectures; 
} 

ArrayList<Lecture> lectures; 

public String getName() { 
    return name; 
} 

public void setName(String name) { 
    this.name = name; 
} 
} 


class Lecture { 
String timming,subject,teachers,rooms; 

public String getTimming() { 
    return timming; 
} 

public void setTimming(String timming) { 
    this.timming = timming; 
} 

public String getSubject() { 
    return subject; 
} 

public void setSubject(String subject) { 
    this.subject = subject; 
} 

public String getTeachers() { 
    return teachers; 
} 

public void setTeachers(String teachers) { 
    this.teachers = teachers; 
} 

public String getRooms() { 
    return rooms; 
} 

public void setRooms(String rooms) { 
    this.rooms = rooms; 
} 
}

這是我的API響應

我想利用上述響應到數組列表，該代碼我使用

TimeResponse timeResponse = (TimeResponse) responseObj; 
     nameList = new ArrayList<>(); 

     for (TimeMain timeMain : timeResponse.getTimeMains()) { 
      nameList.add(timeMain.getName()); 
     }

TimeResponse類

public class TimeResponse { 
ArrayList<TimeMain> timeMains; 

public ArrayList<TimeMain> getTimeMains() { 
    return timeMains; 
} 

public void setTimeMains(ArrayList<TimeMain> timeMains) { 
    this.timeMains = timeMains; 
} 
}

請你精確你在哪個行號得到錯誤？ –

製作其中一個[MCVE]請 – LW001

您使用的是api調用和gson轉換器的庫？ – sabbibJAVA

List<TimeMain> timeList = new Gson().fromJson(json, new TypeToken<List<TimeMain>>(){}.getTypeToken());

應該做的工作
