im also faced this problem in Nexus 4 (Android 4.4 version) and fixed it like this..
view = inflater.inflate(R.layout.cus_actionbar_top, null);
actionbar.setCustomView(view);
actionbar.setDisplayShowCustomEnabled(true);
actionbar.setDisplayShowHomeEnabled(false);
actionbar.setHomeButtonEnabled(false);
View homeIcon = findViewById(Build.VERSION.SDK_INT >=
Build.VERSION_CODES.HONEYCOMB ? android.R.id.home: R.id.abs__home);
((View) homeIcon.getParent()).setVisibility(View.GONE);
actionbar.setDisplayShowTitleEnabled(false);
