大家好，我是android studio的新手，我做了一个活动，通过viewpage2和适配器让我浏览3个片段

public class MainActivity extends AppCompatActivity {

    private Button buttonContinue;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mainactivity);
        ViewPager2 viewPager2; = findViewById(R.id.mainactivity_viewpager);
        MyAdapter adapter; = new MyAdapter(this);

        viewPager2.setAdapter(adapter);
        Button button = findViewById(R.id.mainactivity_button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(viewPager2.getCurrentItem() +1 < adapter.getItemCount()){
                    viewPager2.setCurrentItem(viewPager2.getCurrentItem()+1);
                }
            else
                FirstAccessActivity.this.finish();

            }
        }
    }
 }

现在我希望这个适配器不总是返回这3个片段，而是基于以某种方式传递的条件，它只返回第一个和第三个片段，或者只返回第二个片段，我该怎么办？

public class Adpter extends FragmentStateAdapter {

    public Adpter(@NonNull FragmentActivity fragmentActivity) {
        super(fragmentActivity);
    }
    @NonNull
    @Override
    public Fragment createFragment(int position) {
        switch (position){
            case 0:
                return new FragmentOne();
            case 1:
                return new FragmentTwo();
            case 2:
                return new FragmentThree();
            default:
                return null;
        }
    }

    @Override
    public int getItemCount() {
        return 3;
    }
}
