我使用Android工作室,当我承诺在GitHub上回购并查看git的差异我看到一个红色的标记线处与警告"在文件末尾不换行"几个文件的末尾.如何配置Android Studio以确保它在每个文件的文件文件中添加换行符.谢谢.

我有一个recyclerview,其中每个列表项都有一个带4个单选按钮的radiogroup.如何正确存储每个放射组的状态.这是我的代码.在向上/向下滚动时,状态是不相关的.谢谢

public class ElementListAdapter extends RecyclerView.Adapter<ElementListAdapter.ViewHolder> {

    private List<Element> elements = new ArrayList<>();
    private Context context;

    private int[] state;

    public ElementListAdapter(Context context, List<Element> elements) {
        this.context = context;
        this.elements = elements;

        this.state = new int[elements.size()];
        Arrays.fill(this.state, -1);
    }

    @Override
    public ElementListAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item_layout, parent,
                false);

        return new ViewHolder(v);

我使用AChartEngine生成散点图.我目前正在使用XYMultipleSeriesRenderer在单个图表视图中渲染两个散点图.如何为每个散点图设置不同的点大小

final XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer();
.
.
renderer.setPointSize(5.5f);  // this changes point size for all scatter charts

// Scatter chart1
XYSeriesRenderer r1 = new XYSeriesRenderer();
r1.setColor(Color.BLACK);
r1.setPointStyle(PointStyle.CIRCLE);
r1.setFillPoints(true); 
renderer.addSeriesRenderer(r1);

// Scatter chart2
XYSeriesRenderer r2 = new XYSeriesRenderer();
r2.setColor(Color.YELLOW);
r2.setPointStyle(PointStyle.CIRCLE);
r2.setFillPoints(true); 
renderer.addSeriesRenderer(r2);

我希望散点图的两个点都有不同的半径.任何帮助将不胜感激.谢谢
