Android棒棒糖接触色

Question

如何选择联系人徽章的颜色。使用什么算法？

Answer 1

它没有保存。它使用Contact name字符串的哈希码来确定颜色。

示例：

String name = "Harish";
int colors[] = new int[] { Color.RED, Color.GREEN, Color.BLUE};

int chosenColor = colors[Math.abs(name.hashCode()) % colors.length];

我从这个answer

中学到了什么

Answer 2

您可以试试像这样的颜色生成器..

    protected void Application_Error(object sender, EventArgs e)
    {
        var lastException = Server.GetLastError();

        var wrappedContext = new HttpContextWrapper(Context);
        wrappedContext.Response.StatusCode = (lastException as HttpException)?.GetHttpCode() ?? 500;
        wrappedContext.Response.Clear();
        wrappedContext.Response.TrySkipIisCustomErrors = true;
        wrappedContext.Server.ClearError();

        var routeData = new RouteData();
        routeData.Values.Add("area", "");
        routeData.Values.Add("controller", "Error");
        routeData.Values.Add("action", "Index");
        routeData.Values.Add("httpResponseCode", Context.Response.StatusCode);

        IController errorController = DependencyResolver.Current.GetService<ErrorController>();
            errorController.Execute(new RequestContext(wrappedContext, routeData));
    }
