Answer 1

It is recommended to put the Toolbar layout xml in a separate file:

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/actionBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:contentInsetEnd="0dp"
app:contentInsetStart="0dp" >

Then include it in your main.xml

<include layout="@layout/view_action_bar" />

Also make sure to : app:contentInsetStart="0dp" this is the main issue for your magins.

In your ActionBar layout file give the android:heigth as match parent for the Parent View. I also had a same issue with it.
