Android API 21 Toolbar Padding

Question

How do I get rid of the extra padding in the new Toolbar with Android SDK API version 21 (the support library)?

I am talking about the red arrows on this picture:

Here is the code I am using:

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:background="?attr/colorPrimary"
        android:padding="0dp"
        android:layout_margin="0dp">

        <RelativeLayout
            android:id="@+id/action_bar_layout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_margin="0dp"
            android:padding="0dp"
            android:background="#000000">

            <Spinner
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"/>

        </RelativeLayout>
</Toolbar>

As you can see I've set all the relevant padding to 0, but there is still padding around the Spinner. What have I done wrong or what do I need to do to get rid of the extra padding?

Edit Some have questioned why I am trying to do this.

As per the Material Design specs, the spinner should be 72dp from the left side

I need to neutralize the padding Google have put there in order to properly place my spinner:

As per Chris Bane's answer below I set the contentInsetStart to 0. For the support library you will need to use the app namespace:

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

     <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:minHeight="@dimen/action_bar_height"
        android:background="?attr/colorPrimary"
        android:contentInsetStart="0dp"
        android:contentInsetLeft="0dp"
        app:contentInsetLeft="0dp"
        app:contentInsetStart="0dp"
        app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light">

</android.support.v4.widget.DrawerLayout>

I hope this helps someone, it had me confused for several days.

Answer 1

Ok so if you need 72dp, couldn't you just add the difference in padding in the xml file? This way you keep Androids default Inset/Padding that they want us to use.

So: 72-16=56

Therefor: add 56dp padding to put yourself at an indent/margin total of 72dp.

Or you could just change the values in the Dimen.xml files. that's what I am doing now. It changes everything, the entire layout, including the ToolBar when implemented in the new proper Android way.

Dimen Resource File

The link I added shows the Dimen values at 2dp because I changed it but it was default set at 16dp. Just FYI...

Make your toolbar like:

<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/menuToolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="0dp"
android:background="@color/white"
android:contentInsetLeft="10dp"
android:contentInsetRight="10dp"
android:contentInsetStart="10dp"
android:minHeight="?attr/actionBarSize"
android:padding="0dp"
app:contentInsetLeft="10dp"
app:contentInsetRight="10dp"
app:contentInsetStart="10dp"></android.support.v7.widget.Toolbar>

You need to add

contentInset

attribute to add spacing

Answer 3

((Toolbar)actionBar.getCustomView().getParent()).setContentInsetsAbsolute(0,0);

Answer 4

A combination of

android:padding="0dp" In the xml for the Toolbar

and

mToolbar.setContentInsetsAbsolute(0, 0) In the code

This worked for me.
