Android 使用viewBinding制作的BaseFragment在viewpager2中使用的时候不起作用

我的BaseFragment

public abstract class BaseFragment extends ViewBinding> extends Fragment {

    public T binding;

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        Type type = this.getClass().getGenericSuperclass();
        if (type instanceof ParameterizedType) {
            // 如果支持泛型
            try {
                // 获得泛型中的实际类型，可能获得多个，[0]就是获得T的type
                Class<T> tClass = (Class<T>) ((ParameterizedType) type).getActualTypeArguments()[0];
                // 通过反射获取inflate
                Method method = tClass.getMethod("inflate", LayoutInflater.class, ViewGroup.class, Boolean.class);
                // 获得viewBinding实例
                binding = (T) method.invoke(null,getLayoutInflater(),container, false);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        return binding.getRoot();
    }

    @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        init();
    }

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        binding = null;
    }

    protected abstract void init();
}

我的适配器类

public class ChartVPAdapter extends FragmentStateAdapter {

    private List fragments;

    public void setFragments(List f) {
        fragments.clear();
        fragments.addAll(f);
        notifyDataSetChanged();
    }

    public ChartVPAdapter(@NonNull FragmentActivity fragmentActivity) {
        super(fragmentActivity);
        fragments = new ArrayList<>();
    }

    @NonNull
    @Override
    public Fragment createFragment(int position) {
        return fragments.get(position);
    }

    @Override
    public int getItemCount() {
        return fragments.size();
    }
}

只要一运行就会报

Attempt to invoke interface method 'android.view.View androidx.viewbinding.ViewBinding.getRoot()' on a null object reference

求解

 dataBinding = DataBindingUtil.inflate(inflater, layoutId(), container, false)

直接这样写就行了，，，用不上反射

 Method method = tClass.getMethod("inflate", LayoutInflater.class, ViewGroup.class, Boolean.class);

改成

 Method method = tClass.getMethod("inflate", LayoutInflater.class, ViewGroup.class, boolean.class);
