如何使用sw限定词为“小型”设备创建布局？

Question

As I understand layout-small , layout-normal , layout-large are deprecated and the recommended way of creating layout for a devices' set is to use sw. For example layout-sw320 is for devices which have one of it's side with value >= 320dp. But "small" and "normal" devices have the same sw.

So the question is how properly distinguish "small" and "normal" devices with sw qualifier? Is it possible? Do I need to fall back to old style ?

Answer 1

The new device dimension classifiers aim to support based on the smallest width of the device; not so much the height. If your application is relying on the height, you will have to support the orientations separately or disable them using the screenOrientation property in the AndroidManifest.xml <activity> attribute.

For example, using screenOrientation="sensorPortrait|portrait" allows you to rely on the swXXX only, but if you support all screen orientations you can support them with:

• layout-w320-port , which is called for small and large screens in the old specification when in portrait
• EDIT: You could use layout-w320-h426-port and layout-w320-h470-port when you want to differentiate between the two in portrait mode specifically.
• layout-w426-land for the previous small screen, when in landscape orientation
• layout-w470-land for the previous large screen, when in landscape orientation

Hope this helps!

in manifest -

<supports-screens android:resizeable=["true"| "false"]
                  android:smallScreens=["true" | "false"]
                  android:normalScreens=["true" | "false"]
                  android:largeScreens=["true" | "false"]
                  android:xlargeScreens=["true" | "false"]
                  android:anyDensity=["true" | "false"]
                  android:requiresSmallestWidthDp="integer"
                  android:compatibleWidthLimitDp="integer"
                  android:largestWidthLimitDp="integer"/>
