1. Theme.
File->settings, search theme, click Appearance, select Darcula in the theme of the right panel.
2. Comment Shortcut keys.
File->settings, search Keymap, point open keymap, search on the right panel, find Other->fix doc comment, double click, choose Add Keyboard Shortcut, press your shortcut key. In Eclipse it's ALT + Shift +J, but there's a conflict here, so I'm using a near shortcut key combination: ALT + SHIFT + K. Android Studio's shortcuts are much smarter than eclipse for modifying document annotations, such as adding parameters.
3, the member variable prefix.
If you name the member variable used to prefix with a m, but generate getter and setter, and do not want to have this m in the method name, can be set as follows.
File->settings->code Style->java, then select the Code generation tag in the right panel, Naming,field this line with the corresponding name prefix plus m.
4. Sorting methods.
If you always adjust the way you write, so that you can make calls or function-related methods close to each other, you can set this up.
As the 3rd step, select Arrangment in the label, hook keep dependent methods together, you can choose whether to sort by breadth or by depth.
