首先，3.2以前是設置不同的small , normal, large, xlarge來解決
3.2以後通過設置最小的DP長度或者寬度來設置，比如layout-sw600dp
To help you target some of your designs for different types of devices, here are somenumbers for typical screen widths:
- 320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc).
- 480dp: a tweener tablet like the Streak (480x800 mdpi).
- 600dp: a 7” tablet (600x1024 mdpi).
- 720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).
res/layout/main_activity.xml # For handsets res/layout-sw600dp/main_activity.xml # For tablets
還要在manifest裏設置下最小的那個長度或者寬度。
<manifest ... > <supports-screens android:requiresSmallestWidthDp="600" /> ... </manifest>
- Use
wrap_content,fill_parent, ordpunits when specifyingdimensions in an XML layout file - Do not use hard coded pixel values in your application code
- Do not use
AbsoluteLayout(it's deprecated) - Supply alternative bitmap drawables for different screen densities
2 不要用固定的PX爲單位
3. 不要用絕對佈局
4. 設置不同分辨率的圖片自適應
