New Theme.AppCompat ActionBar Height

When using version 21 of the appcompat library, it ?android:attr/actionBarSize

returns 48 dips as if it were a Holo theme and not Material. This is actually a little more - 56 failures.

Has anyone found a workaround for this problem?

There is no workaround. If you are using ?android:attr/actionBarSize

android will look for the value in the plattform you are using. The result will be 48dp if you are using Android version below 5.0, obviously.
Since you are using a library appcompat-v7

in your project, you should use ?actionBarSize

. This will return 56dp as expected because the system will look for a value in your project that has a BarSize action defined due to the appcompat library.

If you'd like to try it yourself, here's a little code snippet to test the described behavior:



int[] textSizeAttr = new int[] { android.R.attr.actionBarSize, R.attr.actionBarSize };
TypedArray a = obtainStyledAttributes(new TypedValue().data, textSizeAttr);
float heightHolo = a.getDimension(0, -1);
float heightMaterial = a.getDimension(1, -1);

Log.d("DEBUG", "Height android.R.attr.: " + heightHolo + "");
Log.d("DEBUG", "Height R.attr.: " + heightMaterial + "");

Note. ... This will return the size in pixels. As an example on my Nexus 5, which is currently running 4.4, it returns 144px (48dp) for android.R.attr.actionBarSize and 168px (56dp) for R.attr.actionBarSize.

They worked for me using appcompact v-21



 <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
            <item name="android:actionBarSize">46dp</item>
            <item name="actionBarSize">46dp</item>
    </style>
