主要的处理方法：
/**
* 格式化超链接文本内容并设置点击处理
* */
private CharSequence getClickableHtml(String html) {
Spanned spannedHtml = Html.fromHtml(html);
SpannableStringBuilder clickableHtmlBuilder = new SpannableStringBuilder(spannedHtml);
URLSpan[] urls = clickableHtmlBuilder.getSpans(0, spannedHtml.length(), URLSpan.class);
for(final URLSpan span : urls) {
setLinkClickable(clickableHtmlBuilder, span);
}
return clickableHtmlBuilder;
}
/**
* 设置点击超链接对应的处理内容
* */
private void setLinkClickable(final SpannableStringBuilder clickableHtmlBuilder,final URLSpan urlSpan) {
int start = clickableHtmlBuilder.getSpanStart(urlSpan);
int end = clickableHtmlBuilder.getSpanEnd(urlSpan);
int flags = clickableHtmlBuilder.getSpanFlags(urlSpan);
ClickableSpan clickableSpan = new ClickableSpan() {
public void onClick(View view) {
LogW.i("URL-click:"+urlSpan.getURL());
}
};
//实际使用过程中，可根据需要清空之前的span，防止出现重复调用的情况
//clickableHtmlBuilder.clearSpans();或者clickableHtmlBuilder.removeSpan(urlSpan);
clickableHtmlBuilder.setSpan(clickableSpan, start, end, flags);
}
实际调用场景：
//一串带超链接的文本内容
String context = "这是一个测试内容<a href='https:www.baidu.com'>点我跳转</a>";
TextView textview = findviewById(R.id.textview);
textview.setText(getClickableHtml(context );
//这一句很重要，否则ClickableSpan内的onClick方法将无法触发！！
textview.setMovementMethod(LinkMovementMethod.getInstance());
