Follow this steps:

3. Under code style section, select xml tab.

Reset the appropriate Android code style as follows.

It seems the default scheme leaves out the "attribute" property in the arrangement rules. Adding them back in works like a charm for me.

The correction can be made in: Preferences > Editor > Code Style > XML

Just adding more details .

This is a known issue with android studio from Android Studio 3.5 Canary 8 . It should get fixed in next version as this turned out to affect large number of developers .
