android studio 代码快捷键

android  studio 的代码快捷键，代码块

////输出打印

Groovy(常规部分)---->

serr --->System.err.println("example")

souf --->printf "example"

sout --->println "example"

soutm --->System.out.println("MainActivity.onCreate");//当前类的当前方法名

soutp --->System.out.println("savedInstanceState = [" + savedInstanceState + "]");//这个好，可以打印出当前方法的所有参数列表及其值

soutv --->System.out.println("params",params);//即 你可以输出打印一个变量值

//（常规的代码块儿）

Iteractions--->//快速生成代码块儿

fori --->for (int i = 0; i < ; i++) {}

itar --->for (int i = 0; i < Array.length; i++) { int i1 = Array[i];}//遍历数组

itco --->for (Iterator iterator = collection.iterator(); iterator.hasNext(); ) {

Object next = iterator.next();

}//这个是遍历一个容器变量的，直接让容器返回一个iterator进行遍历

iten --->while (枚举类.hasMoreElements()) { Object nextElement = 枚举类.nextElement(); }//enumeration 是一个枚举类接口来着。遍历枚举内容

iter --->for (int i : FOCUSED_STATE_SET) {...}//遍历选中状态下的set

itit --->while (iterator.hasNext()) { Object next = iterator.next(); }//获取到了迭代器对象后，对迭代器进行遍历操作

itli --->for (int i = 0; i < list.size(); i++) { Object o = list.get(i); }//遍历list对象里面的内容

ritar --->for (int i = Array.length - 1; i >= 0; i--) { int i1 = FOCUSED_STATE_SET[i]; }//倒叙遍历数组

//其他的（综合）

geti --->public static MainActivity getInstance() { return ; }//获取到当前的实例 的代码模板

ifn --->if (某变量 == null) {....}//生成if null代码块儿

inn --->if (某变量 != null) {....}//生成if not null代码块儿

inst --->if ($EXPR$ instanceof $TYPE$) { $TYPE$ $VAR1$ = ($TYPE$)$EXPR$; $END$ }//判断某变量是不是某个类的实例对象

lazy --->if (savedInstanceState == null) { savedInstanceState = new Bundle(); }//执行延迟初始化，就是对象直到用的时候才进行初始化操作

mn --->var1 = Math.min(var2,var3);//得到比较两个变量值小的代码块

mx --->var1 = Math.max(var2,var3);//得到比较两个变量值大的代码块

psvm --->public static void main(String[] args){ 。。。。 }//生成一个main()函数的代码块

toar --->something.toArray(new collection[collection.size()])//这个是生成一个代码块用于把collection的对象存储到一个数组里面去.实用！

//普通的代码（修饰符部分的）

psf --->public static final 

psfi --->public static final int 

psfs --->public static final String 

St --->String 

thr --->throw new 

IDEA 快捷键

 

这是从IDEA官网下载的IDEA keymap Windows/Linux，中文我会慢慢补充上去。

因为AS是基于IDEA社区版开发的，所以快捷键都AS同样适用。

IntelliJ IDEA Default Keymap

与Ubuntu系统快捷键冲突的地方

Here’s a list of tweaks you need to make with default system key bindings so that they won’t interfere with IntelliJ IDEA actions (listed in brackets).

• Disable the Shade window action, assigned to Ctrl + Alt + S (Settings dialog)
• Change or disable the Lock Screen action, assigned to Ctrl + Alt + L (Reformat code)
• Change or disable the Launch terminal action, assigned to Ctrl + Alt + T (Surround with)
• Change or disable the Switch to workspace action, assigned to Сtrl + Alt + Arrows (Navigation)
• Disable the Move window action, assigned to Alt + F7 (Find usages)
• Change or disable the Resize window action, assigned to Alt + F8 (Evaluate expression
