Android--屏幕适配通用

使用步骤：

1、以某一widthDP为基准，生成所有设备对应的dimens.xml文件

<?xml version="1.0" encoding="UTF-8"?> <resources> <!-- Your custom size defind by references, can be writted in anywhere, any module, any values/*.xml, for example: --> <dimen name="common_margin">@dimen/dp_15</dimen> <!-- dp and sp values, must be defind in this file! --> <!-- view size,you can add if there is no one --> <dimen name="dp_m_60">-60dp</dimen> <dimen name="dp_m_30">-30dp</dimen> <dimen name="dp_m_20">-20dp</dimen> <dimen name="dp_m_12">-12dp</dimen> <dimen name="dp_m_10">-10dp</dimen> <dimen name="dp_m_8">-8dp</dimen> <dimen

2、在Android Studio中安装ScreenMatch插件，如图：

3、插件安装好后，在项目的任意目录或文件上右键，选择ScreenMatch选项。如图：

然后选择在哪个module下执行适配。即基于哪个module下的res/values/dimens.xml文件作为基准dimens.xml文件，生成的其他尺寸dimens.xml文件放在哪个module下。

点击确认然后再看看res目录下会自动生成一堆dimens.xml文件，如下：

通过上面的步骤就已经生成了所有设备对应的dimens.xml文件。

因为默认生成的是下列最小宽度dp的dimens.xml文件
384,392,400,410,411,480,533,592,600,640,662,720,768,800,811,820,960,961,1024,1280,1365，如果不需要或者需要增加某些dp值的dimens.xml文件，则需要修改配置文件，即screenMatch.properties文件（修改前先删除之前生成的全部dimens.xml文件）。配置文件在我们执行完成上面的命令后，会在项目的目录下自动生成，如下：

2、根据设计图标注，在布局写上对应的值。

在安卓中，系统密度为160dpi的中密度手机屏幕为基准屏幕，即320×480的手机屏幕。在这个屏幕中，1dp=1px。320x480分辨率对应的其他分辨率的比例如下：

所以，如果UI给的是720x1280分辨率的图， 那么dp = px / 2， 给的是1080x1920分辨率的图，那么 dp = px / 3，即根据比例即可。

举例：UI在720x1280上做的图，其中一个按钮的宽高分辨为：宽720px，高为100px，字体大小为30px，在布局中则这样使用：

 <Button android:layout_width="@dimen/dp_360" android:layout_height="@dimen/dp_50" android:textSize="@dimen/sp_15"/> 

代码中动态设置dp或sp：
如果需要在代码中动态设置dp或sp，则需要通过getDimension（）方法获取对应资源文件下的dp或sp值再设置（具体参考github上的demo）。如下：

 /*获取sp值*/ float pxValue = getResources().getDimension(R.dimen.sp_15);//获取对应资源文件下的sp值 int spValue = ConvertUtils.px2sp(this, pxValue);//将px值转换成sp值 mTvShowParams.setTextSize(spValue);//设置文字大小 /*获取dp值*/ float pxValue2 = getResources().getDimension(R.dimen.dp_360);//获取对应资源文件下的dp值 int dpValue = ConvertUtils.px2dp(this, pxValue2);//将px值转换成dp值 

怎么适配其他module?

• 问题：在项目的其他module中怎么实现适配？难道也要多套dimens？
• 解决：并不需要多套dimens，只需要在values文件夹下有一套与app module一样的dimens文件即可达到适配。因为经过编译，所有module中的dimen数据都会统一归类到主module（即app module）中的values/dimens.xml文件中了，然后系统又会根据你设置的值去找对应values-swxxxdp文件夹下的dimens.xml文件中的值。
• 验证：在项目中建一个module，然后随便取一个dimens.xml文件中的值进行打印，分别运行在不同widthDP的设备上（用模拟器即可）观察打印的结果发现确实是这样的。
