I Am trying to create an actionbar without the app logo/text, and with a centralised picture, and i know it is possible with a custom view, here is my code:
All post above collapsing the home icon but leaving a blank space. For avoiding that you need to set the logo size to zero . Below added my code snippet.it may help for others who struggle with same problem.thanks
actionBar.setLogo(new ColorDrawable(Color.TRANSPARENT));
View homeIcon = findViewById(
Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ?
android.R.id.home : R.id.abs__home);
((View) homeIcon.getParent()).setLayoutParams(new LinearLayout.LayoutParams(0, 0));
((View) homeIcon).setVisibility(View.GONE);
