Android Perfect Fit Multi-resolution summary

Android adaptation, before the work is to 1280*720 interface to adapt to work, but now the resolution of the mobile phone into the 2K era, so now art are 1920*1080 to do interface design. Based on previous work experience, summed up the appropriate plan.

1. Tools: Markman This is a must-have measurement tool (do not update the download after installation, otherwise the measured data will not be saved)

2. Understand the resolution principle (0.75, 1, 1.5, 2.0, 3.0)

3. Know what resolution to develop the interface.

To be aware is the tablet development, VALUES-SW600DP, Values-sw720dp-land. These two files are mainly used for tablet storage.

SW720DP means that the minimum width is 720DP, such as a 1280*800 device, the density of 1 is 10-inch tablet, its width is 1280dp, so it takes priority to VALUES-SW720DP file to find resources, and then go to SW600DP, Have not found the drawable-mdpi to find, and then look up (high density file), and finally go to drawable-ldpi find!

Example steps:1. The following are 1920*1080, measuring the desired pixel size:

2. Then create the Dimens.xml file in the values file

3. Unified use in Layout!

Such as:

<?xml version= "1.0" encoding= "UTF-8"? ><linearlayout xmlns:android= "http://schemas.android.com/apk/res/ Android "    android:layout_width=" fill_parent "    android:layout_height=" fill_parent ">    < Framelayout        android:id= "@+id/frame"        android:layout_width= "@dimen/px120dp"        android:layout_height= "@ Dimen/dp40 ">    </FrameLayout></LinearLayout>
