参考技术A settings --> Editor --> Live Templates

private ()
private static class SingletonHolder
public static instance = new ();

​
public static ins()
return SingletonHolder.instance;

​</pre>

private static final String TAG = " ";
private ()
/**

避免重复造轮子贴出来俩：

还需要你选择一下选择一下name的表述才行 比如我是想要class 那就拿classname()吧，ok了 就这样了

天真了吧！这样生成出来的肯定不是你想要自动补齐类名的东西！！！

你以为这样就完了？

Androidstudio的快捷键

只记忆常用的快捷键。

1，alt+enter导包，抛异常什么的，用来自动修正的

2，Ctrl+alt+V自动补全

3，Alt+Insert 生成代码(如get,set方法,构造函数等)

4，Ctrl+H 显示类结构图

5，3.Ctrl＋[或]可以跳到大括号的开头结尾

6， Ctrl+alt+F抽局部变量未成员变量
