问题描述
测验结束时，随机显示这2个片段。 但是我需要为每个片段添加一个计时器。我该如何实现？
我已经发布了MCQ Fragment的代码，其他的也一样。 （仅接口有所不同）我想知道我到底需要在哪里放置计时器。
ActivityMCQ.java（MCQ-片段）
public class ActivityMCQ extends Fragment implements View.OnClickListener {
private ImageView iv_yellow_bin,iv_red_bin,iv_black_bin,iv_blue_sharp_Box,iv_white_sharp_Box,iv_question_image;
private TextView tv_name_of_image;
private int current_questionMCQ,current_questionTrueFalse;
private int score;
private ArrayList<Question> mSQSList = new ArrayList<>();
private ArrayList<Question> trueFalseQsList = new ArrayList<>();
private boolean isFirstMCQ,isFirstTrueFalse;
private static final int TOTAL_NO_OF_QS = 13;
private TextView timer;
public View onCreateView(@NonNull LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.activity_mcq,container,false);
tv_name_of_image = root.findViewById(R.id.tv_name_of_image);
iv_yellow_bin = root.findViewById(R.id.iv_yellow_bin);
iv_red_bin = root.findViewById(R.id.iv_red_bin);
