如何将数据从RecyclerAdapter类发送到主活动

public interface DataListener {
    void onDataReceived(String data);
}

public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ViewHolder> {
    private DataListener dataListener;

    public void setDataListener(DataListener listener) {
        this.dataListener = listener;
    }

    // 其他代码...
}

if (dataListener != null) {
    dataListener.onDataReceived(data);
}

public class MainActivity extends AppCompatActivity implements DataListener {
    // 其他代码...

    @Override
    public void onDataReceived(String data) {
        // 处理接收到的数据
    }
}

RecyclerAdapter adapter = new RecyclerAdapter();
adapter.setDataListener(this);
