How to correctly create a 9Patch of waters of such a picture
UPD : Do not look at the fact that it is lighter on top and darker below, the main thing for me is to understand how to repeat such lines so that it turns out beautifully, here is the picture I need
UPD 2: If for the web I made something like this picture size 3 by 3
and repeated it, then how can I use it in an android project? and specify it as a background?
9Patch it only stretches, but I need to repeat it

So that the output has a small and stretchable picture, or tell me how to do the same on pure XML

<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
  android:src="@drawable/bg_pic" 
  android:tileMode="repeat" />

After that, on the element where you need such a background
