Android MainActivity无法转换为Bottomsheetlistener

public class MainActivity extends AppCompatActivity implements BottomSheetListener {
    // MainActivity的其他代码

    @Override
    public void onBottomSheetItemSelected(String item) {
        // 处理底部弹出窗口选项被选择的事件
        // 可以根据选项执行相应的操作
    }
}

public class BottomSheetFragment extends BottomSheetDialogFragment {
    private BottomSheetListener mListener;

    @Override
    public void onAttach(@NonNull Context context) {
        super.onAttach(context);
        try {
            mListener = (BottomSheetListener) context;
        } catch (ClassCastException e) {
            throw new ClassCastException(context.toString()
                    + " must implement BottomSheetListener");
        }
    }

    // 其他底部弹出窗口的代码

    private void onItemSelected(String item) {
        mListener.onBottomSheetItemSelected(item);
    }
}
