프래그먼트 버튼 질문드려요~

Question

버튼 클릭시 숫자 증가 예제를 보면서 프래그먼트에서 다음과 같이 기입을 하였는데요 

JAVA

@Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View RootView = inflater.inflate(R.layout.content_main, container, false);
        // onCreateView = Layout을 inflater하여 View작업을 하는 곳
        final ArcSeekBar arcSeekBar = (ArcSeekBar)RootView.findViewById(R.id.seekArc);
        mhztext = (TextView)RootView.findViewById(R.id.hztext);
        mtimebar = (TextView)RootView.findViewById(R.id.timebar);

        // 타이머 버튼
        left_btn = (Button)RootView.findViewById(R.id.left_btn);
        left_btn.setOnClickListener(this);
        right_btn = (Button)RootView.findViewById(R.id.right_btn);
        right_btn.setOnClickListener(this);
        // hz 버튼
        hz_left=(Button)RootView.findViewById(R.id.hz_left);
        hz_left.setOnClickListener(this);
        hz_right=(Button)RootView.findViewById(R.id.hz_right);
        hz_right.setOnClickListener(this);

        arcSeekBar.setProgress(0);
        mhztext.setText("");

        return RootView;
    }    

    @Override
    public void onClick(View v) {
        Log.d("Content_Main","onClick:"+v.getId());
        switch(v.getId()) {
        // 시간 -10초
        case R.id.left_btn:
            count-=10;
            mtimebar.setText(""+count);
            break;

        // 시간 +10초
        case R.id.right_btn:
            count+=10;
            mtimebar.setText(""+count);
            break;

        // Hz -1
        case R.id.hz_left:
            count--;
            mhztext.setText(""+count);
            break;

        // Hz +1
        case R.id.hz_right:
            count++;
            mhztext.setText(""+count);
            break;
        default:
            break;
        }

코드 기입을 하고 나서 테스트 중에 숫자가 변경이 안되서 로그캣 창을 보니 다음과 같이 출력이

되는데 어디서 잘못된지 모르겠어서 질문드려요

왜 콘스트레인트 레이아웃이 겹쳐있나요?
이너 레이아웃이 x , y 값이 없어서 하위 뷰들의 실제 영역도 틀어진 것 같아요.
이너뷰를 제거해보심이 어떨까요
