how can I remove button bottom border

Issue

I want to use custom background on android button without any border and with radius only on top of the button and I make the drawable like that but the problem I got a gray line in the bottom of the button how I can remove it I already using style="@android:style/Widget.Holo.Button.Borderless" but it didn't make anything

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape android:shape="rectangle">
        <solid android:color="@color/turquoise" />
    </shape>
</item>
<item>
    <shape android:shape="rectangle">
        <corners
            android:bottomLeftRadius="0dp"
            android:bottomRightRadius="0dp"
            android:topLeftRadius="14dp"
            android:topRightRadius="14dp" />
        <solid android:color="@color/white" />
        <size android:height="60dp" />
    </shape>
</item>

and here is the button used in the layout

<Button
      android:id="@+id/btn_bg"
      style="@android:style/Widget.Holo.Button.Borderless"
      android:layout_width="match_parent"
      android:layout_height="60dp"
      android:clickable="false"
      android:background="@drawable/custom_bg_white"
      android:textSize="14sp"
      android:visibility="visible" />

Solution

this gray line is not border it's the elevation that is made by the button style if you don't want it set android:elevation=0dp and set android:stateListAnimator="@null"
