无法将数据从RecyclerView适配器传递到Viewpager适配器

public interface DataTransferInterface {
    void transferData(Object data);
}

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> implements DataTransferInterface {
    private DataTransferInterface dataTransferInterface;

    // 其他代码...

    @Override
    public void transferData(Object data) {
        if (dataTransferInterface != null) {
            dataTransferInterface.transferData(data);
        }
    }

    public void setDataTransferInterface(DataTransferInterface dataTransferInterface) {
        this.dataTransferInterface = dataTransferInterface;
    }

    // 其他代码...
}

public class ViewPagerAdapter extends PagerAdapter implements DataTransferInterface {

    // 其他代码...

    @Override
    public void transferData(Object data) {
        // 处理传递过来的数据
    }

    // 其他代码...
}

public class MainActivity extends AppCompatActivity {
    private RecyclerViewAdapter recyclerViewAdapter;
    private ViewPagerAdapter viewPagerAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // 初始化RecyclerView适配器和ViewPager适配器
        recyclerViewAdapter = new RecyclerViewAdapter();
        viewPagerAdapter = new ViewPagerAdapter();

        // 将RecyclerView适配器的DataTransferInterface实例设置给ViewPager适配器
        viewPagerAdapter.setDataTransferInterface(recyclerViewAdapter);
