Kotlin中的生成器函数:

  val text = buildSpannedString {
      append("My red text")
      setSpan(
          ForegroundColorSpan(ContextCompat.getColor(requireContext(), R.color.red)),
          3,
          6,
          Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
      )
  }
  textView?.setText(text)

你可以使用Spannable应用效果到你的TextView:

这是我的例子，只是一个TextView文本的第一部分上色(同时允许您动态设置颜色，而不是硬编码成字符串与HTML的例子!)

    mTextView.setText("Red text is here", BufferType.SPANNABLE);
    Spannable span = (Spannable) mTextView.getText();
    span.setSpan(new ForegroundColorSpan(0xFFFF0000), 0, "Red".length(),
             Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

在这个例子中，你可以将0xFFFF0000替换为getResources().getColor(R.color.red)

if (Build.VERSION.SDK_INT >= 24) {
     Html.fromHtml(String, flag) // for 24 API  and more
 } else {
     Html.fromHtml(String) // or for older API 
 }

用于24个API及以上(标志)

public static final int FROM_HTML_MODE_COMPACT = 63;
public static final int FROM_HTML_MODE_LEGACY = 0;
public static final int FROM_HTML_OPTION_USE_CSS_COLORS = 256;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_BLOCKQUOTE = 32;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_DIV = 16;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_HEADING = 2;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_LIST = 8;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_LIST_ITEM = 4;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_PARAGRAPH = 1;
public static final int TO_HTML_PARAGRAPH_LINES_CONSECUTIVE = 0;
public static final int TO_HTML_PARAGRAPH_LINES_INDIVIDUAL = 1;

如果你想在strings.xml中给出文本颜色和文本大小，那么检查下面的代码:

<string name="txt_my_string">
    <font fgcolor='#CFD8DC' > Text with given color </font> // Custom text color
    <font size="14" > Text with given size </font> // Custom Text size
    <font fgcolor='#3A55EA' size="14" > Text with given color and size </font> // Custom text color and size
</string>

希望你能容易理解:)

你可以在没有HTML的情况下打印多种颜色的行:

TextView textView = (TextView) findViewById(R.id.mytextview01);
Spannable word = new SpannableString("Your message");        

word.setSpan(new ForegroundColorSpan(Color.BLUE), 0, word.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

textView.setText(word);
Spannable wordTwo = new SpannableString("Your new message");        

wordTwo.setSpan(new ForegroundColorSpan(Color.RED), 0, wordTwo.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.append(wordTwo);

是的，如果你用html的font-color属性格式化字符串，然后把它传递给方法html . fromhtml(你的文本在这里)

String text = "<font color=#cc0029>First Color</font> <font color=#ffcc00>Second Color</font>";
yourtextview.setText(Html.fromHtml(text));
