XML文件的代码

<br><br>由上，AutoCompleteTextView 默认是输入二个字符自动提示。如果想设置输入第一个字符就进行提示，添加代码如下:<br><textarea name="code" src="/img/2012/06/24/1443447572.gif"><br><br><br></p><p>?</p><pre></pre> </p></div><div style="margin:0 auto;width:300px;height:250px;position:relative;"> <script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> <!-- 移动端全站正文 --> <ins class="adsbygoogle" style="display:block" data-ad-client="ca-pub-6147101717324856" data-ad-slot="1958144088" data-ad-format="auto"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({}); </script></div> <div class="subn-nav"><a href="//m.reader8.net">读书人网</a> ><a href="//m.reader8.net/jiaocheng/yidongkfa/">移动开发</a></div><div class="sp-jctu"><h3><span> 热点推荐 </span></h3><ul><li><p><a href="//m.reader8.net/jiaocheng/20130906/1400173.html">20款移动开发框架平台介绍</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20130906/1391611.html">微信公众平台如何保证access_token长期</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140426/2314936.html">中国城市列表相仿手机通讯录显示方式</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140426/2314935.html">Socket连接与HTTP联接</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140425/2313936.html">平添wifi定位功能</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140425/2313935.html">偷空写了两个游戏</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140424/2313088.html">java集合类 - 实现 细节</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140424/2313087.html">hidden visible display 的差别</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140423/2311956.html">春节前最后一个：立地群飞</a></p></li> <li><p><a href="//m.reader8.net/jiaocheng/20140423/2311955.html">64位 与32 位 差异</a></p></li> </ul></div><div style="display:none;"> <script> var _hmt = _hmt || []; (function() { var hm = document.createElement("script"); hm.src = "//hm.baidu.com/hm.js?d6151f323a57d16696165e47eee86d53"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(hm, s); })(); </script></div> <div class="footer"><p>触屏版 | <a href="//www.reader8.net/jiaocheng/20120817/1402821.html#fromapp">电脑版</a></p><p>读书人网 m.reader8.net</p></div> <script language="javascript"> function clickme(sad){ var divobjdiv = document.getElementById("divobjdiv" + sad); if(divobjdiv.style.display =="none"){ divobjdiv.style.display ="block"; }else{ divobjdiv.style.display ="none"; } var wenzi = document.getElementById('divobjimg' + sad); if(wenzi.innerText == "收起"){ wenzi.innerText = "查看更多"; }else{ wenzi.innerText = "收起"; } } </script> <div id="back-top"><a href="#top"><span></span></a></div> </body> </html>
