Android API 21 Toolbar Padding
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.
Solution 1:
The left inset is caused by Toolbar's contentInsetStart
which by default is 16dp.
Change this to 72dp to align to the keyline.
Update for support library v24.0.0:
To match the Material Design spec there's an additional attribute contentInsetStartWithNavigation
which by default is 16dp. Change this if you also have a navigation icon.
Solution 2:
Above answer is correct but there is still one thing that might create issues (At least it did create an issue for me)
I used the following and it doesn't work properly on older devices -
android:contentInsetStart="0dp"
android:contentInsetLeft="0dp"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
The trick is here just use the following -
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
and get rid of -
android:contentInsetStart="0dp"
android:contentInsetLeft="0dp"
And now it should work fine throughout all the devices.
Hope it helps.
Solution 3:
Simpley add this two line in toolbar. Then we get new removed left side space bcoz by default it 16dp.
android:contentInsetStart="0dp"
app:contentInsetStart="0dp"
Solution 4:
In case someone else stumbles here... you can set padding as well, for instance:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
int padding = 200 // padding left and right
toolbar.setPadding(padding, toolbar.getPaddingTop(), padding, toolbar.getPaddingBottom());
Or contentInset:
toolbar.setContentInsetsAbsolute(toolbar.getContentInsetLeft(), 200);
