How to reduce the gap between navigation icon and toolbar title?

Question

My problem is the extra space between the nav-drawer icon and toolbar title. The sample images are below:

The xml view of the toolbar is

<android.support.v7.widget.Toolbar         android:id="@+id/toolbar"         android:layout_width="match_parent"         android:layout_height="?attr/actionBarSize"         android:background="?attr/colorPrimary"         app:titleTextAppearance="@style/Toolbar.TitleText"         app:popupTheme="@style/AppTheme.PopupOverlay" /> 

I have tried to solve this problem by using code below but no change occurred.

@Override protected void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.activity_home);     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);     setSupportActionBar(toolbar);      //toolbar.setTitleMarginStart(0);     toolbar.setTitleMarginStart(-8); } 

Is there any way to solve this problem ?

Add

app:contentInsetLeft="0dp" app:contentInsetStart="0dp" app:contentInsetStartWithNavigation="0dp" 

to the ToolBar.

Complete Code :

<android.support.v7.widget.Toolbar         android:id="@+id/toolbar"         android:layout_width="match_parent"         android:layout_height="?attr/actionBarSize"         android:background="?attr/colorPrimary"         app:titleTextAppearance="@style/Toolbar.TitleText"         app:popupTheme="@style/AppTheme.PopupOverlay"         app:contentInsetLeft="0dp"         app:contentInsetStart="0dp"         app:contentInsetStartWithNavigation="0dp" />
