简单的例子

在you strings.xml中

<string name="str_privacy_policy">This is our Privacy Policy.</string>

如果你想让“隐私政策”特别加粗，就在加粗标签之间加字符串。

像这样

<string name="str_privacy_policy">This is our <b>Privacy Policy.</b></string>

结果是

这是我们的隐私政策

这里有一个更好的解决方案，如果你想使多个文本粗体。我改进了Eitan的代码。谢谢你搞清楚。

public static SpannableStringBuilder makeSectionOfTextBold(String text, String... textToBold) {
    SpannableStringBuilder builder = new SpannableStringBuilder(text);

    for (String textItem :
            textToBold) {
        if (textItem.length() > 0 && !textItem.trim().equals("")) {
            //for counting start/end indexes
            String testText = text.toLowerCase(Locale.US);
            String testTextToBold = textItem.toLowerCase(Locale.US);
            int startingIndex = testText.indexOf(testTextToBold);
            int endingIndex = startingIndex + testTextToBold.length();

            if (startingIndex >= 0 && endingIndex >= 0) {
                builder.setSpan(new StyleSpan(Typeface.BOLD), startingIndex, endingIndex, 0);
            }
        }
    }

    return builder;
}

public static Spanned getBoldString(String textNotBoldFirst, String textToBold, String textNotBoldLast) {
    String resultant = null;

    resultant = textNotBoldFirst + " " + "<b>" + textToBold + "</b>" + " " + textNotBoldLast;

    return Html.fromHtml(resultant);

}

试试这个。这绝对有帮助

只需在标签中添加这个

dangerouslySetInnerHTML={{__html: "<p>Your html text here.<p>"}}

找到了一种方法，如果你想处理多种语言的本地化，这很无聊，但它是有效的，让我们假设我们想要这样:

英文:

没有付款记录

西班牙语:

没有付款记录

你必须创建3个字符串

中文:

<string name="start_string">There are no</string>
<string name="middle_string">payments</string>
<string name="end_string">registered.</string>
<string name="string_format" translatable="false">%1$s %2$s %3$s</string>

西班牙语:

<string name="start_string">No hay</string>
<string name="middle_string">pagos</string>
<string name="end_string">registrados</string>

现在你可以这样做:

val startSpanPosition = getString(R.string.start_string).length
val endSpanPosition = startSpanPosition + getString(R.string.middle_string).length
val mySpannableString = SpannableStringBuilder(String.format(getString(R.string.string_format),
        getString(R.string.start_string), getString(R.string.middle_string))), getString(R.string.end_string)))

mySpannableString.setSpan(StyleSpan(Typeface.BOLD), spanStartPosition, endSpanPosition, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)

字符串资源

<resources>
   <string name="your_string_resource_name">This is normal text<![CDATA[<b> but this is bold </b>]]> and <![CDATA[<u> but this is underline text</u>]]></string>
</resources> 

您的Java类

yourtextView.setText(getString(R.string.your_string_resource_name));
