3. Templates
Improve efficiency, essential skills for home and travel.
1. Live Template
Examples of standard templates
ViewConstructors: One-click generation of constructors when customizing View
starter: One-click generation of startActivity call
For more standard templates, see Preferences->Editor->Live Templates

2. Custom Templates
Standardizing template usage, unifying logging and singleton writing
Singleton template
Log template
3. Postfix Completion
Common examples
For more usage, see Preferences->Editor->General->Postfix Completion

4. Plugins
1. IdeaVim
Vim plugin, can change AS’s editing mode to vim’s editing mode, but the custom functions are not as powerful as normal vim, if you don’t want to leave the mouse, this plugin is a good choice, refer to vim for usage
2. AceJump
This is a plugin for quickly positioning the cursor, with functionality similar to vim’s easyJump plugin. This plugin allows you to get rid of the mouse, the cursor can jump wherever you want.
3. ParcelableGenerator
Used to quickly generate parcelable objects
4. CodeGlance
Displays a thumbnail of the editor in the sidebar, similar to Sublime’s effect, if you are fond of Sublime’s style, you can give it a try
5. Eclipse Code Formatter
Helps AS support Eclipse-style code style configurations, unifying code style Android source code includes a set of code style standard configurations
5. FindBugs-IDEA
A static code defect analysis tool, can be installed with one click in AS plugin management, no configuration required. Supports custom analysis scope, can be used with the scopes settings, can also be used with svn to only analyze the current modification. Convenient and easy to use, recommended!
6. Some Hot Cold Knowledge
1. Scopes & TODO
Scopes function is to set a range, this function is very useful when developing new modules, can unify the code files involved in the new functionality into a new scopes. This makes it easy to use tools like Find-bugs for static code analysis.
The second is to combine with the todo function, which can quickly list the todos marked in the code to prevent omissions.
2. Subversion
AS provides a version control plugin that supports svn and git, needs configuration. When using the svn plugin, you need to enable command line settings during installation, which is not enabled by default. There are many online, so I won’t post specific steps here. Before submitting code using svn, it will first perform a code analysis similar to Find-bugs. If there are defects in the static analysis code, it will not be submitted and will prompt for modification. This is a great feature!
3. Spelling
Is a spell check feature that supports dictionary configuration, default is English. For those who often misspell words, this is a great feature
