AlertDialog.Builder with undue space

I have a space in the bottom of my custom AlertDialog. I do not know why it's happening, knowing that I did not set any margins or padding at the end of my view. If anyone can help.

Here is a real print of what is happening

Resolved!

The problem is that I was using layout_marginTop negative, and somehow, the layout did not recalculate the height, because the element went up, but pro layout it remains there in the same position.

I was like this ...

<View
    android:layout_width="fill_parent"
    android:layout_height="1dp"
    android:background="#C0C1C0"
    android:layout_marginTop="-19dp"/>

When I removed -19, the space on the bottom disappeared. And then when I put the View inside a LinearLayout, I was able to put negative margin without having the space problem at the end.

Now it's like this ...

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">

    <View
        android:layout_width="fill_parent"
        android:layout_height="1dp"
        android:background="#C0C1C0"
        android:layout_marginTop="-9dp"/>

</LinearLayout>

Solved. Thank you for your help! Thanks.
