change actionbar color and icons based on condition

Question

I created an app with navigation drawer. I want to change the color of actionbar and default icon of drawer to be changed on selection of a particular navigation menu item and it should change to default values on selection of any other item.

My code

Fragment fragment;
if(fragment.toString().contains("HomeFragment")){
            ab = ((BaseActivity)getApplicationContext()).getSupportActionBar();
            ab.setHomeButtonEnabled(true);
            ab.setDisplayHomeAsUpEnabled(true);
            ab.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#FFFFFF")));
            ab.setElevation(0);
            ab.setDisplayHomeAsUpEnabled(true);
            ab.setHomeAsUpIndicator(R.drawable.username);
    }

I could change actionbar color and navigation drawer icon with the above code,but can't change to default color and icon on other navigation item selection.

fragment is never initialized. Anyway inside your fragment findviewbyid and setonclicklistener onclick myviewitem.setbackground... — Pomagranite
that is not complete code. fragment is initialized and its working fine. When i select "HomeFragment" color of action bar is changing. But i cant change navigation drawer icon . — Visakh

Just continue your code

Fragment fragment;
if(fragment.toString().contains("HomeFragment")){
            ab = ((BaseActivity)getApplicationContext()).getSupportActionBar();
            ab.setHomeButtonEnabled(true);
            ab.setDisplayHomeAsUpEnabled(true);
            ab.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#FFFFFF")));
            ab.setElevation(0);
            ab.setDisplayHomeAsUpEnabled(true);
            ab.setHomeAsUpIndicator(R.drawable.username);
    } else {
      ab = ((BaseActivity)getApplicationContext()).getSupportActionBar();
            ab.setHomeButtonEnabled(true);
            ab.setDisplayHomeAsUpEnabled(true);
            ab.setBackgroundDrawable(new ColorDrawable(Color.parseColor("your default color")));
            ab.setElevation(0);
            //ab.setHomeAsUpIndicator(R.drawable.username); change it to your other icon;
}
