Navigation Drawer Android API specific Layout Attribute

Question

Hello I have created a navigation drawer with ListView navigation using ActionBar Sherlock and android support Library v4 for old version compatbil

Answer 1

I am not sure if you really need to use android dimensions (like listPreferredItemHeightSmall etc.) In some android version can that dimension be 12 and in other 14. I suggest you to create your own dimension, which will be used in your whole app, and you can easily edit them when change is needed.

Answer 2

To support lower versions, instead of removing the following three parameters,

  android:textAppearance="?android:attr/textAppearanceListItemSmall" 
  android:background="?android:attr/activatedBackgroundIndicator"
  android:minHeight="?android:attr/listPreferredItemHeightSmall"

You can actually replace them with equivalent values/resources.

The equivalent values can be obtained from https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/themes.xml

Now,

• a) android:textAppearance="@android:style/TextAppearance.Medium"

• b)

  1. Download a selector from https://github.com/habzy/Test0011_DialerPad/blob/master/res/drawable/list_item_activated_background.xml

  2. In the above project browse the resources in hdpi,mdpi etc and get files named list_activated_holo.9.png

  3. Finally

  android:background="@drawable/list_item_activated_background"

• c) From the equivalent values obtained , we know that listPreferredItemHeightSmall is 48dip

  android:minHeight="48dip"
