在网页底部使用一个辅助的可扩展类作为Android字符串资源共享。你可以通过创建charsquences并给它们一个样式来实现。

但在他们给我们的例子中，只是粗体，斜体，甚至是彩色文本。我需要在aCharSequence中包装几个样式，以便在TextView中设置它们。所以这个类(我命名为charsequencestyle)，我只是添加了这个函数。

public static CharSequence applyGroup(LinkedList<CharSequence> content){
    SpannableStringBuilder text = new SpannableStringBuilder();
    for (CharSequence item : content) {
        text.append(item);
    }
    return text;
}

在视图中我添加了这个。

            message.push(postMessageText);
            message.push(limitDebtAmount);
            message.push(pretMessageText);
            TextView.setText(CharSequenceStyles.applyGroup(message));

我希望这对你有帮助!

如上所述，使用TextView.setText(Html.fromHtml(String))

在Html格式的字符串中使用这些标签:

<a href="...">
<b>
<big>
<blockquote>
<br>
<cite>
<dfn>
<div align="...">
<em>
<font size="..." color="..." face="...">
<h1>
<h2>
<h3>
<h4>
<h5>
<h6>
<i>
<img src="...">
<p>
<small>
<strike>
<strong>
<sub>
<sup>
<tt>
<u>

如果你不喜欢使用html，你可以创建一个styles.xml并像这样使用它:

TextView tv = (TextView) findViewById(R.id.textview);
SpannableString text = new SpannableString(myString);

text.setSpan(new TextAppearanceSpan(getContext(), R.style.myStyle), 0, 5, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
text.setSpan(new TextAppearanceSpan(getContext(), R.style.myNextStyle), 6, 10, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

tv.setText(text, TextView.BufferType.SPANNABLE);

使用SpannableString而不是html标记更轻量级。它帮助我看到可视化的例子，所以这里是一个补充的答案。

这是一个单一的TextView。

// set the text
SpannableString s1 = new SpannableString("bold\n");
SpannableString s2 = new SpannableString("italic\n");
SpannableString s3 = new SpannableString("foreground color\n");
SpannableString s4 = new SpannableString("background color\n");
SpannableString s5 = new SpannableString("underline\n");
SpannableString s6 = new SpannableString("strikethrough\n");
SpannableString s7 = new SpannableString("bigger\n");
SpannableString s8 = new SpannableString("smaller\n");
SpannableString s9 = new SpannableString("font\n");
SpannableString s10 = new SpannableString("URL span\n");
SpannableString s11 = new SpannableString("clickable span\n");
SpannableString s12 = new SpannableString("overlapping spans\n");

// set the style
int flag = Spanned.SPAN_EXCLUSIVE_EXCLUSIVE;
s1.setSpan(new StyleSpan(Typeface.BOLD), 0, s1.length(), flag);
s2.setSpan(new StyleSpan(Typeface.ITALIC), 0, s2.length(), flag);
s3.setSpan(new ForegroundColorSpan(Color.RED), 0, s3.length(), flag);
s4.setSpan(new BackgroundColorSpan(Color.YELLOW), 0, s4.length(), flag);
s5.setSpan(new UnderlineSpan(), 0, s5.length(), flag);
s6.setSpan(new StrikethroughSpan(), 0, s6.length(), flag);
s7.setSpan(new RelativeSizeSpan(2), 0, s7.length(), flag);
s8.setSpan(new RelativeSizeSpan(0.5f), 0, s8.length(), flag);
s9.setSpan(new TypefaceSpan("monospace"), 0, s9.length(), flag);
s10.setSpan(new URLSpan("https://developer.android.com"), 0, s10.length(), flag);
s11.setSpan(new ClickableSpan() {
    @Override
    public void onClick(View widget) {
        Toast.makeText(getApplicationContext(), "Span clicked", Toast.LENGTH_SHORT).show();
    }
}, 0, s11.length(), flag);
s12.setSpan(new ForegroundColorSpan(Color.RED), 0, 11, flag);
s12.setSpan(new BackgroundColorSpan(Color.YELLOW), 4, s12.length(), flag);
s12.setSpan(new UnderlineSpan(), 4, 11, flag);

// build the string
SpannableStringBuilder builder = new SpannableStringBuilder();
builder.append(s1);
builder.append(s2);
builder.append(s3);
builder.append(s4);
builder.append(s5);
builder.append(s6);
builder.append(s7);
builder.append(s8);
builder.append(s9);
builder.append(s10);
builder.append(s11);
builder.append(s12);

// set the text view with the styled text
textView.setText(builder);
// enables clicking on spans for clickable span and url span
textView.setMovementMethod(LinkMovementMethod.getInstance());

这个例子最初的灵感来自这里。

事实上，除了Html对象，你也可以使用Spannable类型类，例如textappearance espan或TypefaceSpan和SpannableString一起。Html类也使用这些机制。但是使用Spannable类型类，您有更多的自由。
