推荐答案

试试这个

txtTest.setText( Html.fromHtml("<a href="http://www.google.com">Google</a>"));
txtTest.setMovementMethod(LinkMovementMethod.getInstance());

记住:不要使用 android:autoLink="web" 属性.因为它导致 LinkMovementMethod 不起作用.

Remember : don't use android:autoLink="web" attribute with it. because it causes LinkMovementMethod doesn't work.

SDK 24+ 更新Android N (SDK v24) 已弃用Html.fromHtml函数，转而使用此方法:

Update for SDK 24+ The function Html.fromHtml deprecated on Android N (SDK v24), so turn to use this method:

    String html = "<a href="http://www.google.com">Google</a>";
    Spanned result = HtmlCompat.fromHtml(html,Html.FROM_HTML_MODE_LEGACY);
    txtTest.setText(result);
    txtTest.setMovementMethod(LinkMovementMethod.getInstance());

以下是标志列表:

FROM_HTML_MODE_COMPACT = 63;
FROM_HTML_MODE_LEGACY = 0;
FROM_HTML_OPTION_USE_CSS_COLORS = 256;
FROM_HTML_SEPARATOR_LINE_BREAK_BLOCKQUOTE = 32;
FROM_HTML_SEPARATOR_LINE_BREAK_DIV = 16;
FROM_HTML_SEPARATOR_LINE_BREAK_HEADING = 2;
FROM_HTML_SEPARATOR_LINE_BREAK_LIST = 8;
FROM_HTML_SEPARATOR_LINE_BREAK_LIST_ITEM = 4;
FROM_HTML_SEPARATOR_LINE_BREAK_PARAGRAPH = 1;

更新 2使用 android.text.util.Linkify，现在更容易制作可点击的 TextView:

Update 2 with android.text.util.Linkify, it's more easier now to make a clickable TextView:

TextView textView =...
Linkify.addLinks(textView, Linkify.WEB_URLS);
