如何解决：在Android中使用linkify类时无法切换？

参考上面的链接，当我测试样本并添加linkify getView函数时，切换不起作用

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

            SpeechView sv;           

            if (convertView == null) {
                sv = new SpeechView(mContext, myTitle[position], myContent[position], mExpanded[position]);
            } else {

                sv = (SpeechView)convertView;                
                sv.setTitle(myTitle[position]);
                sv.setDialogue(myContent[position]);
                sv.setExpanded(mExpanded[position]); 

                TextView body = (TextView)sv.getChildAt(1);
                body.setTextColor(Color.GRAY); 

                body.setText(myContent[position]);
                Linkify.addLinks(body, Linkify.PHONE_NUMBERS);     

               body.setMovementMethod(LinkMovementMethod.getInstance());                     


            }

            TextView title = (TextView)sv.getChildAt(0);
            title.setTextColor(Color.LTGRAY);              


            return sv;
        }
