十五:多分辨率适配常用目录
最后更新于:2022-04-01 06:42:39
一个好的App必须要支持绝大多数市面上的设备,适配繁多的分辨率一度让我们陷入了分辨率的海洋。无论如何,这个工作是逃不掉的。
* * *
我们可以用多个layout目录对不同分辨率进行单独布局,如下:
~~~
layout-large-mdpi (1024x600)
layout-large-tvdpi (800x1280)
layout-large-xhdpi (1200x1920)
layout-xlarge-mdpi (1280x800)
layout-xlarge-xhdpi (2560x1600)
~~~
或者直接使用下面这样:
~~~
layout-640x360
layout-800x480
~~~
* * *
与layout对应的,有不同的drawable:
~~~
res/drawable (default)
res/drawable-ldpi/ (240x320 and nearer resolution)
res/drawable-mdpi/ (320x480 and nearer resolution)
res/drawable-hdpi/ (480x800, 540x960 and nearer resolution)
res/drawable-xhdpi/ (720x1280 - Samsung S3, Micromax Canvas HD etc)
res/drawable-xxhdpi/ (1080x1920 - Samsung S4, HTC one, Nexus 5, etc)
~~~
* * *
用不同的layout毕竟工作量巨大,我们的实践是用不同的values来对应同layout中的值,目录如下:
~~~
res/values/dimens.xml(default)
res/values-ldpi/dimens.xml (240x320 and nearer resolution)
res/values-mdpi/dimens.xml (320x480 and nearer resolution)
res/values-hdpi/dimens.xml (480x800, 540x960 and nearer resolution)
res/values-xhdpi/dimens.xml (720x1280 - Samsung S3, Micromax Canvas HD, etc)
res/values-xxhdpi/dimens.xml (1080x1920 - Samsung S4, HTC one, etc)
res/values-large/dimens.xml (480x800)
res/values-large-mdpi/dimens.xml (600x1024)
res/values-sw600dp/dimens.xml (600x1024)
res/values-sw720dp/dimens.xml (800x1280)
res/values-xlarge-xhdpi/dimens.xml (2560x1600 - Nexus 10")
res/values-large-xhdpi/dimens.xml (1200x1920 - Nexus 7"(latest))
~~~
有时必须要考虑到密度,如下:
~~~
ldpi 120dpi 0.75
mdpi 160dpi 1
hdpi 240dpi 1.5
xhdpi 320dpi 2
~~~
