I would like to have a drawable that looks like the following drawing.

I imagine I need 4 lines; 2 for the tip and one on each side. I don't understand how to:

• Give the 2 tip lines a length (ex.: 5dp)
• Position lines relative to each other (stacked horizontally)
• Allow the side lines to expand to fill the parent (with one having X% of space and the other (100-tip-X)%.

This is what I have so far:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="line">
            <stroke android:width="1dp" android:color="#336699"/>
        </shape>
    </item>
    <item>
        <rotate android:fromDegrees="135" android:toDegrees="135">
            <shape android:shape="line">
                <stroke android:width="1dp" android:color="#330000"/>
            </shape>
        </rotate>
    </item>
    <item>
        <rotate android:fromDegrees="45" android:toDegrees="45">
            <shape android:shape="line">
                <stroke android:width="1dp" android:color="#000033"/>
            </shape>
        </rotate>
    </item>
    <item>
        <shape android:shape="line">
            <stroke android:width="1dp" android:color="#336699"/>
        </shape>
    </item>
</layer-list>

Can anyone point me in the right direction?
