我有一个扩展View.onClickListener的Fragment类，我实现了 @overriden 方法，即onClick。
我有2个imageView，它执行onClickListener。

1. filterIcon.setOnClickListener(this)
2. fab.setOnClickListener(this)
   并在 @overriden 方法中设置两个活动，即**onClick()**。
   我想知道onClickListener是否有可能调用相关的clickEvent？如果有，如何调用？如果没有，为什么？
   下面是我的代码：

public class ExpenseFragment extends Fragment implements View.OnClickListener {
    private TextView totalExpenseTV;
    private FloatingActionButton fab;
    private RecyclerView recyclerView;
    private ImageView filterIcon;
    private PieChart pieChart;

    private Animation rotateForward, rotateBackward;

    private FirebaseRecyclerOptions<ExpenseModel> options;
    private MyAdapter adapter;

    private int calendarImgClick = 0;
    private int groceryClick = 0;
    private int bikeClick = 0;
    private int rentClick = 0;
    private int foodsClick = 0;
    private int beerClick = 0;
    private int setCalClick = 0;

    private String whichCategorySelected = "";
    private String selectedDate;

    public void onViewCreated(@NonNull View attachInParentView, Bundle savedInstanceState) {
        super.onViewCreated(attachInParentView, savedInstanceState);
        findViewByIDS(attachInParentView);
        setupRecyclerView();
        fabAnimation();
        fab.setOnClickListener(this);
        filterIcon.setOnClickListener(this);
        databaseListener();

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_expense, container, false);
    }

    @Override
    public void onClick(View view) {
        fab.startAnimation(rotateForward);
        rotateForward.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {

            }

            @Override
            public void onAnimationEnd(Animation animation) {
                addNote();
            }

            @Override
            public void onAnimationRepeat(Animation animation) {

            }
        });
        filterIcon.setBackgroundResource(R.drawable.filter_off);
    }
