Answer 1

You can do that with the app:layout_anchor and app:layout_anchorGravity attributes:

For example with this code,

<ImageButton
    android:id="@+id/myImageButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="@dimen/fab_margin"
    android:src="@android:drawable/ic_dialog_email"
    app:layout_anchor="@id/toolbar_layout"
    app:layout_anchorGravity="bottom|left|end" 
    />

you anchor myImageButton at the bottom left of toolbar_layout .

Answer 2

Can you check if this works?

android:layout_alignParentTop="true"

I added this to my code and it works but without your code i can't tell you if this is the right thing

If you want to add a button to your BarLayout i think that the code is different.
