android - Bitmap repeat + rounded corners

Question

I am trying to create rectangle with rounded corners and background as repeated bitmaps. I am writing like this, but getting bitmaps in the corners.

Could anyone help out?

background.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

<item>
    <shape>
        <stroke
            android:width="1dp"
            android:color="#FFFFFF" />

        <corners android:radius="50dp" />
    </shape>
</item>
<item>
    <bitmap
        android:src="@drawable/carbon_4"
        android:tileMode="repeat" />
</item>

</layer-list>

I found this post by Romain Guy that's a much easier way to round corners on a tiled bitmap. Here's the short answer:

class CurvedAndTiled extends Drawable {

    private final float mCornerRadius;
    private final RectF mRect = new RectF();
    private final BitmapShader mBitmapShader;
    private final Paint mTilePaint;        

    CurvedAndTiled(
            Bitmap bitmap, 
            float cornerRadius) {
        mCornerRadius = cornerRadius;

        mBitmapShader = new BitmapShader(bitmap,
                Shader.TileMode.REPEAT, Shader.TileMode.REPEAT);

        mTilePaint = new Paint();
        mTilePaint.setAntiAlias(true);
        mTilePaint.setShader(mBitmapShader);             
    }

    @Override
    protected void onBoundsChange(Rect bounds) {
        super.onBoundsChange(bounds);
        mRect.set(0, 0, bounds.width(), bounds.height());
    }

    @Override
    public void draw(Canvas canvas) {
        canvas.drawRoundRect(mRect, mCornerRadius, mCornerRadius, mTilePaint);           
    }

    @Override
    public int getOpacity() {
        return PixelFormat.TRANSLUCENT;
    }

    @Override
    public void setAlpha(int alpha) {
        mTilePaint.setAlpha(alpha);
    }

    @Override
    public void setColorFilter(ColorFilter cf) {
        mTilePaint.setColorFilter(cf);
    }       
}

You just set your view's background drawable to be one of these guys and you're good to go.
