仿酷狗音乐播放器开发日志二十四选项设置窗体的实现（附328行xml布局源码）

转载请说明原出处,谢谢~~ 花了两天时间把仿酷狗的选项设置窗体做出来了,当然了只是做了外观.现在开学了,写代码的时间减少,所以整个仿酷狗的工程开发速度减慢了.今天把仿酷狗的选项设置窗体的布局代码分享出来,给学习duilib布局的朋友做个demo.现在编写的仿酷狗选项设置窗体和原酷狗的窗体不细看几乎看不出差别,控件的布局位置和原酷狗最多只有几个像素的位置差别. 先来看一下原酷狗的选项设置窗体的其中一个页面: 如果还不太会布局的朋友可以先看我前些日子写的关于duilib布局的博客<duilib各种布

第五篇：在SOUI中使用XML布局窗口

窗口布局的概念每一个UI都是由大量的界面元素构成的,在Windows编程,这些界面元素的最小单位通常称之为控件. 布局就是这些控件在主界面上的大小及相对位置. 传统的布局一般使用一个4个绝对坐标来定义一个控件在主窗口的位置.对于窗口是固定大小的界面来说,这种方式是最简单有效的. 然而问题在于在Windows系统上编程,基本上很少有程序的窗口是固定大小的,用户希望它的窗口能够随时调整大小.调整大小后界面里的控件还能够按照一定的规则进行重排. 我自己最讨厌的就是在WM_SIZE里重排控件位置. 随

Android中将xml布局文件转化为View树的过程分析（上）

有好几周没写东西了,一方面是因为前几个周末都有些事情,另外也是因为没能找到好的写作方向,或者说有些话题值得分享.写作,可是自己积累还不够,没办法只好闷头继续研究了.这段时间一边在写代码,一边也在想Android中究竟是如何将R.layout.xxx_view.xml这样的布局文件加载到Android系统的view层次结构中的(即我们常说的view树). 这期间一方面自己研究了下源码,另一方面也在网上搜索了下相关文章,发现了2篇很不错的同主题文章,推荐给大家: http://blog.csdn

Android中将xml布局文件转化为View树的过程分析（下）-- LayoutInflater源码分析

在Android开发中为了inflate一个布局文件,大体有2种方式,如下所示: // 1. get a instance of LayoutInflater, then do whatever you want LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); // 2. you're in some View class, then jus
