I'm trying to create a simple help screen that looks like the the one shown below. I need to have 8 different titles with smaller sized text bodies below them. I have implemented a scroll view, but how do I vary the font sizes?

推荐答案

利用 TextView 能够呈现有限的 HTML 标记集这一事实，您可以在单个 TextView 中获得类似的结果.例如

You can get a similar result in a single TextView by taking advantage of the fact that the TextView has the ability to present a limited set of HTML markup. For example

TextView t = (TextView)findViewById(R.id.text1);

t.setText(Html.fromHtml("<H1><u><em>Title1</em></u></H1>Details for section 1<H1><u><em>Title2</em></u></H1>Detail for Section 2"));

将使用 Title1 作为较大的字体部分标题呈现到 TextView 中，粗体和下划线.

Will render into the TextView with Title1 as a larger font section header, bold and underlined.

这可能满足您的申请.
