Answer 1

You must be creating the 9-patch wrongly. I had also the same issue . You must be drawing the black patch on one side of image. Try to draw the black patch by dragging your mouse two side of image. I hope you can understand my words...........

Answer 2

Nine-patch images on Android must have transparent 1-pixel edge, and have opaque pixels in left-top border (1 pixel wide) specifying which part of image is stretched, and which do not.
