最近开发遇到listView中解析爬虫回来的html数据超链接点击问题。有文字html标签链接和纯网址链接混合。链接点击效果是有了但listview的item点击事件却失效了。现将解决办法和网友们分享下：
主要代码：

 @Override

public View getView(int position, View convertView, ViewGroup parent) {

// TODO Auto-generated method stub

ViewHolder holder;

if (convertView==null) {

holder = new ViewHolder();

convertView = View.inflate(context, R.layout.list_item, null);

holder.mtext = (TextView) convertView.findViewById(R.id.linktest);

convertView.setTag(holder);

}else{

holder = (ViewHolder) convertView.getTag();

}

((ViewGroup)convertView).setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS);//加上次属性使焦点能够传递

Spanned html = Html.fromHtml(list.get(position));

Object[] spans = html.getSpans(0, html.length(), URLSpan.class);

holder.mtext.setAutoLinkMask(Linkify.WEB_URLS);

holder.mtext.setMovementMethod(LinkMovementMethod.getInstance());

holder.mtext.setText(html);

SpannableString ss = (SpannableString) holder.mtext.getText();

for (int i = 0; i < spans.length; i++) {

URLSpan span = (URLSpan) spans[i];

int end = html.getSpanEnd(span);

int start = html.getSpanStart(span);

ss.setSpan(span, start, end, 0);

}

holder.mtext.setOnTouchListener(new OnTouchListener() {

@Override

public boolean onTouch(View v, MotionEvent event) {

// TODO Auto-generated method stub

boolean ret = false;

CharSequence text = ((TextView) v).getText();

Spannable stext = Spannable.Factory.getInstance().newSpannable(text);

TextView widget = (TextView) v;

int action = event.getAction();

if (action == MotionEvent.ACTION_UP ||

action == MotionEvent.ACTION_DOWN) {

int x = (int) event.getX();

int y = (int) event.getY();

x -= widget.getTotalPaddingLeft();

y -= widget.getTotalPaddingTop();

x += widget.getScrollX();

y += widget.getScrollY();

Layout layout = widget.getLayout();

int line = layout.getLineForVertical(y);

int off = layout.getOffsetForHorizontal(line, x);

ClickableSpan[] link = stext.getSpans(off, off, ClickableSpan.class);

if (link.length != 0) {

if (action == MotionEvent.ACTION_UP) {

link[0].onClick(widget);

}

ret = true;

}

}

return ret;

}

});

return convertView;

}
