Far too late for you, but may be useful for others.

You can create a custom View in order to do this. Simply scale your source bitmap to be as high as your view and then draw it repeatedly on the canvas:

public class RepeatingXImageView extends View {

Bitmap bitmap;
Paint paint;

public RepeatingXImageView(Context context) {
    super(context);
}

public RepeatingXImageView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public RepeatingXImageView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}

@Override
protected void onLayout(boolean changed, int left, int top, int right, int bottom) {
    super.onLayout(changed, left, top, right, bottom);
    if(changed) {
        paint = new Paint();
        bitmap = BitmapFactory.decodeResource(getContext().getResources(), R.drawable.seekbar_overlay);
        bitmap = Bitmap.createScaledBitmap(bitmap, bitmap.getWidth(), bottom - top, false);
    }
}

@Override
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);
    if(bitmap == null) return;
    int left = 0;
    while(left < getWidth()) {
        canvas.drawBitmap(bitmap, left, 0, paint);
        left += bitmap.getWidth();
    }
}
}
