Question

我正在获取一个html字符串，我想从中提取href字符串，并且只有这些值可以点击才能在TextView中设置之前启动一些自定义活动。我试过这个

CharSequence sequence = Html.fromHtml(textPost.getDescription());
SpannableStringBuilder strBuilder = new SpannableStringBuilder(sequence);
URLSpan[] urls = strBuilder.getSpans(0, sequence.length(), URLSpan.class);
for(URLSpan span : urls) {
       int start = strBuilder.getSpanStart(span);
       int end = strBuilder.getSpanEnd(span);
       int flags = strBuilder.getSpanFlags(span);
       ClickableSpan clickable = new ClickableSpan() {
               public void onClick(View view) {
                     Log.d("Home Activity", "Clicked yay");         
               }
        };
        strBuilder.setSpan(clickable, start, end, flags);
        strBuilder.removeSpan(span);
}
textHolder.content.setText(strBuilder);

这是对文字的突出显示，但当我点击它们时，日志信息不会被打印

从字符串

中提取超链接

Pattern.compile("[a-z]+:\/\/[^ \n]*").matcher(
"download_recording true Package available http://ab.com click the link").find();

并使其可点击

TextView tv = (TextView) findViewById(R.id.textHolder);
tv.setText(Html.fromHtml(getString(R.string.sampleText)));
tv.setMovementMethod(LinkMovementMethod.getInstance());
