只需在标签中添加这个

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

如果你正在使用Kotlin，使用core-ktx会变得更容易，因为它提供了一种领域特定语言(DSL)来做这件事:

val string: SpannedString = buildSpannedString {
    bold {
        append("foo")
    }
    append("bar")     
}

它提供的更多选项有:

append("Hello There")
bold {
    append("bold")
    italic {
        append("bold and italic")
        underline {
            append("then some text with underline")
        }
    }
}

最后，你只需:

textView.text = string

我认为所选择的答案并没有提供一个令人满意的结果。我写了自己的函数，它有两个字符串;全文和要加粗的文本部分。

它返回一个SpannableStringBuilder，带有从'text'中粗体的'textToBold'。

我发现使子字符串加粗而不用标签包装的能力很有用。

    /**
     * Makes a substring of a string bold.
     * @param text          Full text
     * @param textToBold    Text you want to make bold
     * @return              String with bold substring
     */

    public static SpannableStringBuilder makeSectionOfTextBold(String text, String textToBold){

        SpannableStringBuilder builder=new SpannableStringBuilder();

        if(textToBold.length() > 0 && !textToBold.trim().equals("")){

            //for counting start/end indexes
            String testText = text.toLowerCase(Locale.US);
            String testTextToBold = textToBold.toLowerCase(Locale.US);
            int startingIndex = testText.indexOf(testTextToBold);
            int endingIndex = startingIndex + testTextToBold.length();
            //for counting start/end indexes

            if(startingIndex < 0 || endingIndex <0){
                return builder.append(text);
            }
            else if(startingIndex >= 0 && endingIndex >=0){

                builder.append(text);
                builder.setSpan(new StyleSpan(Typeface.BOLD), startingIndex, endingIndex, 0);
            }
        }else{
            return builder.append(text);
        }

        return builder;
  }

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)

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

我创建了一个静态方法来设置文本粗体的TextView和EditText部分

public static void boldPartOfText(View mView, String contentData, int startIndex, int endIndex){
        if(!contentData.isEmpty() && contentData.length() > endIndex) {
            final SpannableStringBuilder sb = new SpannableStringBuilder(contentData);

            final StyleSpan bss = new StyleSpan(Typeface.BOLD); // Span to make text bold
            final StyleSpan iss = new StyleSpan(Typeface.NORMAL); //Span to make text normal
            sb.setSpan(iss, 0, startIndex, Spanned.SPAN_INCLUSIVE_INCLUSIVE);
            sb.setSpan(bss, startIndex, endIndex, Spannable.SPAN_INCLUSIVE_INCLUSIVE); // make first 4 characters Bold
            sb.setSpan(iss,endIndex, contentData.length()-1, Spanned.SPAN_INCLUSIVE_INCLUSIVE);

            if(mView instanceof TextView)
               ((TextView) mView).setText(sb);
            else if(mView instanceof EditText)
               ((EditText) mView).setText(sb);

        }
    }

另一个更定制的代码

  /*typeFaceStyle can be passed as 

    Typeface.NORMAL = 0;
    Typeface.BOLD = 1;
    Typeface.ITALIC = 2;
    Typeface.BOLD_ITALIC = 3;*/

    public static void boldPartOfText(View mView, String contentData, int startIndex, int endIndex,int typeFaceStyle){
        if(!contentData.isEmpty() && contentData.length() > endIndex) {
            final SpannableStringBuilder sb = new SpannableStringBuilder(contentData);

            final StyleSpan bss = new StyleSpan(typeFaceStyle); // Span to make text bold
            final StyleSpan iss = new StyleSpan(Typeface.NORMAL); //Span to make text italic
            sb.setSpan(iss, 0, startIndex, Spanned.SPAN_INCLUSIVE_INCLUSIVE);
            sb.setSpan(bss, startIndex, endIndex, Spannable.SPAN_INCLUSIVE_INCLUSIVE); // make first 4 characters Bold
            sb.setSpan(iss,endIndex,contentData.length()-1,Spanned.SPAN_INCLUSIVE_INCLUSIVE);

            if(mView instanceof TextView)
                ((TextView) mView).setText(sb);
            else if(mView instanceof EditText)
                ((EditText) mView).setText(sb);
        }
    }
