Use push() to create new child nodes:

databaseReference.child("childName").push();

You are trying to store your data in a "continuous" manner, which is something that JSON objects just aren't designed do. If you are looking for an ordered list, use the priorities property, or you can order the data on the client side. This means that you can just store the data, and then either order client-side, or prioritize the children. I would look to do something like:

databaseReference.child("AdminList").child("uid").setValue(uid);
