Android Studio Self-typesetting

At first it was very tangled in how Android studio had the shortcut keys to self-typesetting and line-wrapping. Find a lot of Internet shortcut keys and not practical. Having said Ctrl+shift+l, I tried it completely useless. It was only in the end that I found the best way. Actually a little funny:

is to first select all the code, CTRL+X first cut. Then paste. Now look at your code is not very comfortable, that is, when pasting. Android Studio has helped you make the layout, so you don't have to bother.
