I've decided to migrate from ActionBarSherlock (ABS) to AppCompat-v7. I ran into a problem. ActionBar became 56dp size instead of 48dp as it was in Holo theme. As I found in AppCompat resources the default action bar size is equal 56dp as in Material design. But I want my action bar looks like action bar in Holo theme. How can I specify necessary size for action bar? Maybe there is AppCompat-v7 with Holo instead of Material?
It is normal.
Appcompat v21
library enables you to bring the Material designs to older Android platforms.
If you would like to change the height you can use a Toolbar in your layout and set your favorite height.
<android.support.v7.widget.Toolbar
android:id=”@+id/my_awesome_toolbar"
android:layout_height="48dp"
android:layout_width="match_parent"
android:background="?attr/colorPrimary" />
In any case I suggest you to adopt the Material Desing and use the standard dimens. You can find more info here.
