Absolute positioning with drag and drop in the Android Studio
I want make a complex layout, with absolute coordinates, I use RelativeLayout, with left and top margins, but there are a lot of objects, and it is hard to write all that coordinates in the text editor, thus I decided to use Design tab, but it doesn't allow to move second button to an arbitrary position, always snap to an existing objects, I found a solution, at first instead of RelativeLayout wrote AbsoluteLayout, did absolute positioning, and then refacored layout_x and layout_y to layout_marginLeft and layout_marginTop, but I want to know is there an option to turn off snapping in the Design tab when root layout is RelativeLayout
No. You can't do absolute positioning in RelativeLayout. It's not "snapping", it's showing you the actual relative payout.
You can only do absolute positioning in AbsoluteLayout.
