how to remove left margin of Android Toolbar?

Question

I'm trying to use toolbar for my project. Here is the code I am using:

<android.support.v7.widget.Toolbar     android:id="@+id/toolbar"     android:layout_width="match_parent"     android:layout_height="?attr/actionBarSize"     android:layout_alignParentTop="true"     android:background="?attr/colorPrimary"     android:contentInsetLeft="0dp"     android:elevation="@dimen/margin_padding_8dp"     android:contentInsetStart="0dp">      <RelativeLayout         android:id="@+id/rlToolbar"         android:layout_width="match_parent"         android:layout_height="match_parent">          <TextView             android:id="@+id/tvTitle"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_centerInParent="true"             android:paddingRight="@dimen/margin_padding_16dp"             android:text="AppBar"             android:textAppearance="@style/TextAppearance.AppCompat"             android:textColor="@color/white"             android:textSize="@dimen/text_size_20sp" />      </RelativeLayout>
