android中用tabLayout写底部导航栏时切换按钮时只切换布局，布局对应的活动没反应

Question

public class Fragment1 extends Fragment {
private LuckyPanView mLuckyPanView;
private ImageView mStartBtn;
@Nullable
@Override

public View onCreateView(LayoutInflater inflater,
                         @Nullable ViewGroup container,
                         @Nullable Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment1, container, false);

    mLuckyPanView = (LuckyPanView) rootView.findViewById(R.id.id_luckypan);
    mStartBtn = (ImageView) rootView.findViewById(R.id.id_start_btn);

    return inflater.inflate(R.layout.fragment1,container, false);
}

public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    Log.d("string","123");
            //抽奖转盘的开始按钮的点击事件
    mStartBtn.setOnClickListener(new View.OnClickListener()
    {

        {
            int count = Integer.valueOf((int)(Math.random()*1000));
