我希望我的慢键加减 0.1，快键加减 1

如何解决我希望我的慢键加减 0.1，快键加减 1

我已经将这种方法用于数字选择器..

我试图覆盖一些方法但是这个只读文件

我怎样才能改变我的慢箭头，使差异为 0.1，快箭头为 1。

下面是java文件

```public class infoFragment extends Fragment {


    private ActualNumberPicker mPicker;
    TextView weight;
    


    @Override
    public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view=inflater.inflate(R.layout.fragment_info,container,false);

        mPicker = (ActualNumberPicker) view.findViewById(R.id.actual_picker);
        weight=view.findViewById(R.id.weight);

        mPicker.setListener(new OnValuechangelistener() {
            @Override
            public void onValueChanged(int oldValue,int newValue) {
                String val=String.valueOf(newValue);
                weight.setText(val);
            }
        });

        return view;
    }
}```


***below is xml file***
