我用这个代码来加粗特定的单词…

    Spanned string = Html.fromHtml("Normal string <b>BOLD STRING</b>");
    textView.setText(string);

只需要在HTML中构建字符串并设置它:

String sourceString = "<b>" + id + "</b> " + name; 
mytextview.setText(Html.fromHtml(sourceString));

这是我使用的Kotlin扩展函数

/**
 * Sets the specified Typeface Style on the first instance of the specified substring(s)
 * @param one or more [Pair] of [String] and [Typeface] style (e.g. BOLD, ITALIC, etc.)
 */
fun TextView.setSubstringTypeface(vararg textsToStyle: Pair<String, Int>) {
    val spannableString = SpannableString(this.text)
    for (textToStyle in textsToStyle) {
        val startIndex = this.text.toString().indexOf(textToStyle.first)
        val endIndex = startIndex + textToStyle.first.length

        if (startIndex >= 0) {
            spannableString.setSpan(
                StyleSpan(textToStyle.second),
                startIndex,
                endIndex,
                Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
            )
        }
    }
    this.setText(spannableString, TextView.BufferType.SPANNABLE)
}

用法:

text_view.text="something bold"
text_view.setSubstringTypeface(
    Pair(
        "something bold",
        Typeface.BOLD
    )
)

.

text_view.text="something bold something italic"
text_view.setSubstringTypeface(
    Pair(
        "something bold ",
        Typeface.BOLD
    ),
    Pair(
        "something italic",
        Typeface.ITALIC
    )
)

这不是最简单的解决方案吗?

<string name="string">Please provide your <b>Name</b> properly</string>

只要使用你想要的字符串:)

结果如下所示:

请填写您的姓名

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)

以防有人使用数据绑定。我们可以像这样定义绑定适配器

@BindingAdapter("html")
fun setHtml(view: TextView, html: String) {
    view.setText(HtmlCompat.fromHtml(html, HtmlCompat.FROM_HTML_MODE_LEGACY))
}

然后我们可以在TextView上使用它

app:html="@{@string/bold_text}"

bold_text在哪里

<string name="bold_text"><![CDATA[Part of text is <b>bold</b>]]></string>
