使用层级观察器hierarchyviewer综合各种布局实现Android QQ2012登陆界面和注册界面

 最近工作比较轻松，项目不忙，所以闲着的时间去研究了自己比较感兴趣的UI界面，确实漂亮的UI能给用户带来良好的体验，在android应用中一直尤为重要，这次模仿的是QQ2012Android版的的最新登陆界面以及部分注册的功能，简洁漂亮的UI给人耳目一新的感觉，但看似简单的布局要真的自己做起来还是会遇到很多的困难，尤其是木有什么美工的基础，先上图片看下做完后的效果，有个别的地方还是与原版有出入的：

               

         

 

首先下载官方最新的QQ2012APK文件，然后将后缀名改为.rar打开后可以获得全部锁需要的图片资源，嘿嘿，好多.9的图片都不需要自己再做了~！，之后既要研究该如何去模仿这款应用的布局了

究竟怎样控制好各个控件之间的排布，如何确定各种布局的嵌套呢？既然是优秀的UI界面，我们来完全模仿，那就可以直接照搬QQ的设计排版，这里我用到了android中自带的

层级观察器hierarchyviewer工具来分析UI的布局，hierarchyviewer是非常之实用的工具，即可以用来优化自己的布局，也可以用来参考别人优秀的布局，在\android-sdk-windows\tools目录下双击即可以使用:

点击Load View Hierarchy 选项进入如下画面，可以分析其中的布局了：

分成四个区域，左边较大的工作区即是当前UI的整体布局，一层级的方式排列展示出来，右侧的分三块区域，上边是左侧的缩略图，中间是当前选中布局的属性介绍，可以点击查看具体的数值，很 方便，下边是点击当前布局的实际效果，通过这些就可以了解当前UI是怎样的布局，具体用到了哪些布局方式和控件，一目了然。

--------------------------------------------------华丽的分割线------------------------------------------------------------------

点击Inspect Scrrenshot，进入如下画面：

左侧区域是当前布局的树状结构，这样看起来布局更容易理解，右侧是当前页面的图像，可以通过鼠标移动十字交叉处选中当前元素，而具体的信息就会在中间显示出来。包括所选地方的颜色值，坐标信息，也可以通过放大来进一步进行细微的操作。通过这个工具，怎么样？是不是可以很轻松的把自己喜欢的UI模仿学习下来呢~！

以下是部分布局的代码，具体的java代码可以自行下载研究，我也写了比较幼稚的注释嘿嘿：

以上只是布局的代码，还有部分功能逻辑的实现在源代码里面，当然只是简单操作，并没有真正实现QQ的注册以及短信的验证等信息，但自己写写逻辑也还不错，总之收获还是蛮多的，不仅仅是布局，也有代码的编写，附上源码，希望和大家一起分享交流
