为啥适配不多赘述,直接上适配方案:
布局适配即根据适配方案之一加载指定布局
正常情况下,默认目录是竖屏,单独增加layout-land适配横屏,反之亦然
android3.0之前,适配指定分辨率,将layout文件夹做如下命名:
layout-1024 × 768
layout-1024 × 600
layout-1280 × 768
android3.0以后,需将高度减去48像素,即底部状态栏的高度:
layout-976 × 768
layout-976 × 600
layout-1232 × 768
如果要区分横竖屏适配(android3.0以后),目录名加上land (横屏)或port(竖屏)
横屏适配:layout-land-1024 × 720
竖屏适配:layout-port-976 × 768
注意:新版本Android程序(Android10以后)命名有改动:
规则:layout-(屏幕高-48px) × 屏幕宽
但有时此定义仍不准确,建议创建一下三级目录即可适配大部分屏幕:
layout
layout-1920 × 1080
layout-2340 × 1080
命名如下:
layout-sw360dp
layout-sw392dp
layout-sw411dp
如果要区分横竖屏适配,目录名加上land (横屏)或port(竖屏)
layout-sw360dp-land
layout-sw360dp-port
此外还有一种目录layout-w360dp,与layout-sw360dp的区别,举例说明
这里的sw代表smallwidth的意思,当你的屏幕的绝对宽度大于360dp时,屏幕就会自动调用layout-sw360dp文件夹里面的布局。
注意:这里的绝对宽度是指手机的实际宽度,与手机横竖屏无关。sw最小宽度是指屏幕宽高的较小值,每个屏幕都是固定的,不会随着屏幕横向纵向改变而改变。
当你的屏幕的相对宽度大于360dp时,屏幕就会自动调用layout-w360dp文件夹里面的布局。
注意:这里的相对宽度是指手机相对放置的宽度;即当手机竖屏时,为较小边的长度;当手机横屏时,为较长边的长度。当屏幕横向纵向切换时,屏幕的宽度是变化的,以变化后的宽度来与原来的宽度相比,看是否使用此资源文件下的资源。
与layout-w360dp的使用一样,只是这里指的是相对的高度。但这种方式很少使用,因为屏幕在纵向上通常能够滚动导致长度变化,不像宽度那样基本固定,因为这个方法灵活性不是很好,google 官方文档建议尽量少使用这种方式。
这里的sw、w、h的 dpi 值计算方式如下
- DisplayMetrics metrics = getResources().getDisplayMetrics();
- int widthDpi = (int) (metrics.widthPixels / metrics.density);
- int heightDpi = (int) (metrics.heightPixels / metrics.density);
sw: 取widthDpi 和heightDpi 的较小值
w: widthDpi
h: heightDpi
鉴于需要生成多个dimens.xml文件,手动添加的代价过于高昂,而且当前已经有插件可以自动生成,目前推荐使用插件:ScreenMatch。
和其他插件的安装一样,Android Studio可以通过Plugin Marketplace中查找插件,如下(图中由于我已经安装成功):
我们需要添加一分dimens.xml文件作为适配的基准,文件内容主要声明尺寸。
- <?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: -->

在插件导入之后,可以在values文件夹右键,选择ScreenMatch选项,然后选择在你添加了dimens.xml文件的module下执行,即可生成多个values文件夹。
在使用了ScreenMatch时,在Module层级的目录下会有一个ScreenMatch配置文件——screenMatch.properties,在其中可以更新配置,如果要更新需要适配的尺寸,可以在如下的代码中进行变动:
- base_dp=600
- # Also need to match the phone screen of [match_dp].
- # If you have another dp values.
- # System default values is 320,360,384,400,432,446.5,480,540,592,600,640,662,720,768,800,820,960,1024,1280,1365
base_dp
是你的基准尺寸,可以在System default values
中添加你需要适配的尺寸,然后重新执行第三步重新生成values及对应的dimens.xml文件。
接下来就是在布局xml文件中去使用大小了,可以采用@dimen/dp_12
类似的方式来获取大小。
举例来说,如果要设计一个大小为宽为100dp,高为80dp的按钮,文字大小为20sp,可以在布局中这么写:
- <Button
- android:layout_width="@dimen/dp_100"
- android:layout_height="@dimen/dp_80"
- android:textSize="@dimen/sp_20"/>
这样的话,系统就会根据当前设备的宽度dp去对应的dimens.xml文件中查到对应的长度了。
代码中的话则需要通过getDimension()
方法获取对应资源文件下的大小,工具类如下:
- public class ScreenSizeUtil {
-
- /**
- * 计算当前的SP的值
- * @param context
- * @param spSize :R.dimen.sp_16
- * @return
- */
- public static int getSP(Context context,@DimenRes int spSize){
-
- float pxValue = context.getResources().getDimension(spSize);//获取对应资源文件下的sp值
- //将px值转换成sp值
- return px2sp(context, pxValue);
- }
-
- /**
- * 计算当前的DP的值
- * @param context
- * @param dpSize :R.dimen.dp_16
- * @return
- */
- public static int getDP(Context context,@DimenRes int dpSize){
- float pxValue = context.getResources().getDimension(dpSize);//获取对应资源文件下的sp值
- //将px值转换成sp值
- return px2dip(context, pxValue);
- }
-
- /**
- * 根据手机的分辨率从 dp 的单位 转成为 px(像素)
- */
- public static int dip2px(Context context, float dpValue) {
- if (context == null) {
- return (int) dpValue;
- }
- final float scale = context.getResources().getDisplayMetrics().density;
- return (int) (dpValue * scale + 0.5f);
- }
-
- /**
- * 根据手机的分辨率从 px(像素) 的单位 转成为 dp
- */
- public static int px2dip(Context context, float pxValue) {
- if (context == null) {
- return (int) pxValue;
- }
- final float scale = context.getResources().getDisplayMetrics().density;
- return (int) (pxValue / scale + 0.5f);
- }
-
- /**
- * px转换为sp
- * @param context
- * @param pxValue

- */
- public static int px2sp(Context context,float pxValue){
- if (context == null) {
- return (int) pxValue;
- }
- final float scale = context.getResources().getDisplayMetrics().scaledDensity;
- return (int) (pxValue / scale + 0.5f);
- }
- }
