android: disable action bar home button -


we have file manager-like application use action bar home button "go in folder structure" action. if user @ top of folder structure, button should disabled.

we set home button when user within sub folder. when reach top folder, disable showing up. 

    // update home     actionbar.setdisplayhomeasupenabled(hasparent);

the problem button still "enabled" in user can press can see visual feedback pressed. want action bar home button disabled in case, when there no parent folder.

i tried calling setdisplayshowhomeenabled(), not disable button in stead removes home button completely.

any ideas? thanks.

did try sethomebuttonenabled()? new api level 14, have skip honeycomb tablets.
