布局与底部导航栏重叠的问题

.setDecorView(activity.getWindow().getDecorView().findViewById(android.R.id.content))
                .build();

 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        mView = inflater.inflate(R.layout.fragment_test, null);
        return mView;
    }


    @Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        mFrameLayout = (FrameLayout) mView.findViewById(R.id.fragmen_fragment);
    }

 .setDecorView(mFrameLayout)//非dialog模式下,设置ViewGroup, pickerView将会添加到这个ViewGroup中
