将监听器添加到ViewGroup，并单击viewgroups子级的listener -如何让这两个都起作用？

public class CustomViewGroup extends LinearLayout {
    private OnChildClickListener mListener;

    public CustomViewGroup(Context context) {
        super(context);
    }

    public CustomViewGroup(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomViewGroup(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    public void setOnChildClickListener(OnChildClickListener listener) {
        mListener = listener;
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        // 判断是否需要拦截事件
        // 如果需要拦截，则返回true；否则返回false
        return true;
    }

    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        // 判断是否需要触发子级View的点击事件
        // 如果需要，则调用接口中定义的方法
        if (mListener != null && ev.getAction() == MotionEvent.ACTION_DOWN) {
            mListener.onChildClick();
        }
        return super.dispatchTouchEvent(ev);
    }

    public interface OnChildClickListener {
        void onChildClick();
    }
}

CustomViewGroup customViewGroup = findViewById(R.id.customViewGroup);
customViewGroup.setOnChildClickListener(new CustomViewGroup.OnChildClickListener() {
    @Override
    public void onChildClick() {
        // 处理子级View的点击事件
    }
});
