Question

I was looking for get the height of my actionbar(sherlock). The value returned is 0.

<style name="AppTheme" parent="Theme.Sherlock.Light.DarkActionBar">
    <item name="actionBarStyle">@style/Widget.AppTheme.ActionBar</item>
    <item name="actionBarSize">48dip</item>
</style>

code :

getSupportActionBar().getHeight()

Answer 1

This didn't work?

// Calculate ActionBar height
TypedValue tv = new TypedValue();
if (getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true))
{
    actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,getResources().getDisplayMetrics());
}
