![]() ![]() This is especially useful to add, remove or reorder new parameters to the method definition. Similarly ⌘ + F6 allows you to update the signature of a method. This doesn’t just work for classes, but also for methods, variables, fields,… Fortunately ⇧ + F6 does all of that for you. Renaming classes is very involved: rename class definition, rename the file and update all references and documentation. Quick edit lines via duplicate and move Rename, update and move Move lines and methods up/downīoth combined provide a powerful way of extending code: you duplicate a line, edit it and move it to its location. Duplicate and delete linesĪfter duplicating you can simply move code up/down by using ⌘ + ↑ and ⌘ + ↓ for lines, or ⇧ + ⌘ + ↑ and ⇧ + ⌘ + ↓ for methods. These shortcuts will work regardless of the cursor position in the line. While autocomplete definitely helps, sometimes it’s faster to directly manipulate lines: ![]() In order to speed up development, you want to reduce the amount of typing to a minimum. ⌥ + ⌘ + C: extract constant (java only).I strongly suggest you look at the examples below, but a quick reference is always useful. This post is part of a series with practical examples on how you to get the most out of Android Studio: Enabling you to refactor more confidently, introduce fewer bugs and increase overall quality as also variables, documentation, etc. This post will zoom in on the most useful refactoring options of Android Studio. The main reason for this is the number of manual steps involved: rename, move, copy-paste,… So wouldn’t it make sense to automate this and have Android Studio do all the work for you? Refactoring can be tedious and easily introduce bugs. ![]()
