解决listview item中有edittext时，弹出框覆盖edittext的问题，需求是软件盘弹出时，把edittext布局推上去

Android的输入法弹出问题，一直是困扰很多开发人员的问题，当输入法弹出时，布局会被压缩，某些控件被遮挡住，但是需求可能并不想让该控件遮挡住，在做输入法的时候，你一定要知道这个属性，android:windowSoftInputMode，他有三个属性，分别是adjustUnspecified，adjustResize，adjustPan。我建议最好不要用默认的，即adjustUnspecified。关于更多这三个属性的知识，我之前的一个博客写的很详细，地址是：http://blog.csdn.net/harryweasley/article/details/49124385

如下图所示： 

当输入法弹出来的时候，会遮盖住登录按钮，但是我现在并不想输入法遮盖住登录按钮，同时希望背景也不会被压缩。

现在的需求是，当输入法弹出后，登录以上的布局（包括登录）向上移动到输入法之上，并且，背景不会被压缩。

如下所示： 

如果想让弹出的输入法，保证界面背景图不被压缩，那么一定要使用adjustPan属性。

看如下图所示的分析： 

一个简单的模型，当输入法弹出的时候，可能登录按钮已经被遮盖住，那么我们只需要让登录按钮以上的布局通过scrollTo方式上移他被遮盖的距离就行了。

下面开始贴代码,代码很简单，先是布局文件：
