Answer 1

Verwenden android:layout_centerInParent="true" für Image und entfernen

   android:layout_alignParentLeft="true" 
       android:layout_alignParentStart="true" 
       android:layout_centerVertical="true" 

Answer 2

Logo in der Mitte auszurichten, verwende ich diesen Code in der entsprechenden Aktivität ..

Dieser Code Sie können

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 
     getSupportActionBar().setLogo(R.drawable.logo_title); 
     getSupportActionBar().setDisplayUseLogoEnabled(true);

Verwendung Linear-Layout und Satz helfen Schwerkraft des linearen Layouts zu zentrieren
