android - 带有 RGB 颜色的 Html 内容在 Android 中不显示，但在 ios(苹果)中完美运行

Question

这是完美的工作

val htmlContent = "<p><span style=\"background-color: #008080;\">Heloo This is new <span style=\"color: #0000ff;\">document</span>&nbsp; <span style=\"background-color: #ffffff;\">&nbsp;TEXTT HHHH<strong>Hhhhhhhh</strong>hhhhhhhhhhhhh</span></span></p>\n" +
                            "<h1><span style=\"background-color: #008080;\"><span style=\"background-color: #ffffff;\">TEst dfsdf&nbsp;</span></span></h1>"

但是当我尝试在下面设置此内容时，Html 内容在 android 中不起作用，但在 ios 中完美运行

<p style="text-align:left;"></p>
<p style="text-align:justify;"><span style="color: rgb(250,197,28);background-color: rgb(255,255,255);font-size: 14px;font-family: Open Sans;"><strong>Yellow </strong></span><span style="color: rgb(0,0,0);background-color: rgb(255,255,255);font-size: 14px;font-family: Open Sans;"><strong>Ipsum</strong></span> <span style="color: rgb(0,0,0);background-color: rgb(255,255,255);font-size: 24px;font-family: Open Sans;">is simply </span><span style="color: rgb(209,72,65);background-color: rgb(255,255,255);font-size: 24px;font-family: Open Sans;">Red</span><span style="color: rgb(209,72,65);background-color: rgb(255,255,255);font-size: 14px;font-family: Open Sans;"> </span><span style="color: rgb(0,0,0);background-color: rgb(255,255,255);font-size: 14px;font-family: Open Sans;">text </span><span style="color: rgb(65,168,95);background-color: rgb(255,255,255);font-size: 14px;font-family: Open Sans;">greenthe </span><span style="color: rgb(0,0,0);background-color: rgb(255,255,255);font-size: 14px;font-family: Open Sans;">printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</span></p>

Kotlin 代码

descriptionTextView.text = Html.fromHtml(
                    htmlContent, Html.FROM_HTML_MODE_LEGACY)

Answer 1

您应该知道 Android TextView 不支持所有 HTML 标签和属性，并且存在一些限制。欲了解更多信息，请查看以下问题:
1. Which HTML tags are supported by Android TextView?
2. Android textview html font size tag

在您的情况下，不支持以下属性:
1.文本对齐
2.字体大小
3.字体系列
如果需要设置颜色，rgb(int, int, int)值也不支持。

解决方案:
1. text-align属性仅支持 start , end和center值(value)观。
2.您可以使用<small>较小字体大小的标签或 <big>标签以获得更大的字体大小。
3.您可以使用<font>标签和face属性来设置字体。
4.使用十六进制颜色代码(例如 #FF0000)代替 rgb 颜色代码(例如 rgb(255, 0, 0))
重要提示:如果 html 标记中有多个属性，请使用 ;[Space] 将它们分隔开。而不是; 。看下面的例子:

这个例子不起作用

<span style="color: #ff0000;background-color: #ffffff;">
    RED
</span>

但是这个有效

<span style="color: #ff0000; background-color: #ffffff;">
    RED
</span>
