textview文本片段点击事件与textview点击事件冲突执行两次（最终解决办法）

开发项目中遇到 需要在一个textview中能够点击@好友跳转 用的是下面的方法：

SpannableString nameSpan = new SpannableString(name);    nameSpan.setSpan(new ClickableSpan() {        @Override        public void onClick(View widget) {            // TODO Auto-generated method stub        }    }, 0, nameSpan.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

但是写好后发现 再点击“@好友“之后会同时执行上面的ClickableSpan的onClick方法和textview的监听器onClick方法。

百思不得其解，在网上搜了一下午都找不到满意的答案，看来都是你抄我的我抄你的，抄来抄去，看着都生气；

最后还是国外某个网站上搜到的，虽然英文不咋好，还是跌跌撞撞搜到了答案；o(╯□╰)o （不说废话了，直接上答案）：

CustomLinkMovementMethod link = (CustomLinkMovementMethod)CustomLinkMovementMethod.getInstance();//textview默认的点击事件可以写在这里，也可以另写（写在这里貌似会有点混乱）link.setOnTextClickListener(new CustomLinkMovementMethod.TextClickedListener() {            @Override            public void onTextClicked() {                Toast.makeText(UserProfileActivity.this, "text Pressed", Toast.LENGTH_LONG).show();            }        });        YOUR_TEXTVIEW.setMovementMethod(link);

只需要上面这一个就可以了，下面两个也不用加了：

YOUR_TEXTVIEW.setMovementMethod(ScrollingMovementMethod.getInstance());//滑动YOUR_TEXTVIEW.setMovementMethod(LinkMovementMethod.getInstance());//开始响应点击事件
