浅谈Android自定义Lint规则的实现 （二）

====== This demo program does Lint checking for the following issues:

[1]Don't use Log/Toast/Handler directly. Use LogUtil/ToastUtil/HandlerUtil instead.
[2]Prefix layout xml file of Activity/Fragment with "activity_"/""fragment_".
[3]Layout resource file in ViewHolder must be named with prefix "item_".
[4]In layout xml file, you should name an view item with specified prefix.
[5]In build.gradle file, version info should refer to gradle-wrapper.properties.
[6]Nested For/If/Try statements can not be more than 3 layers.
[7]A constant should be named with only UPPER CASE letter and underline.
[8]You should not call new Message() directly. Instead, you should use handler.obtainMessage or Message.Obtain().
[9]You should throw your own exception with the one caught in try-catch block.
[10]You should pass in a value or variable as a parameter, rather than passing in the operand and operator as parameters. For example, printName("Lucy") and printName(mName) is legal, while printName(mName1 + mName2) is NOT.

====== CustomLintDemo对Android Lint规则进行了扩展，在不影响Android Lint原有的检查项目的基础上，额外检查以下内容： 【1】不能直接使用log,toast，handler
【2】activity或fragment对应的layout资源，用前缀标示，例如：activity_mediapicker.xml
【3】viewholder关联的资源以item结尾
【4】xml布局文件中使用前缀表明类型，比如，btn_xxx
【5】build.gradle里面那个版本依赖，必须通过 gradle.properties文件中指定
【6】嵌套For/If/Try最大深度3
【7】常量的名称
【8】Message必须采用Message.Obtain获取
【9】throw异常的时候注意把已经捕获的异常也一并带上，例如：throw new ManagerException("数据库异常");应该改成throw new ManagerException("数据库异常",e)
【10】调用特定函数时应该直接传入值或单独的变量作为参数，而不是传入多个操作数和操作符作为变量。比如，printName("Lucy")和printName(mName)是合法的，而printName(mName1 + mName2)是不合法的。

====== 自定义Lint规则的2种检查方法：
1、目前最新版的Android Studio已经把一部分自定义Lint检查的功能集成到了IDE中，直接可见。

2、在终端运行"gradle lint"任务，得到完整Lint报告。

java代码中的扫描有效果，xml文件中的扫描没有效果

ljfxyj2008你好，我跑了一下你的demo，发现java代码中能顺利扫描出来错误，但是好像xml中都没有反应，这是本来就没有集成进去还是我环境有问题？
