最终结果

首先建立一个activity，在里面输出各种类型的数据。为了测试Inner class和Object的效果，我专门建立了一个很简单的内部类User：

      class User {
        private String name;
        private String sex;
        User(String name, String sex) {
            this.name = name;
            this.sex = sex;
        }
        public void log() {
            show();
        }
        private void show() {
            L.d("user");
        }
    }
    

激动人心的测试开始了：

              // string
        String str = fromIntent("key");
        L.d(str != null ? str : "hello world");
        // json
        L.json("[{\"CityId\":18,\"CityName\":\"西安\",\"ProvinceId\":27,\"CityOrder\":1},{\"CityId\":53,\"CityName\":\"广州\",\"ProvinceId\":27,\"CityOrder\":1}]'");
        // object
        L.Object(new User("jack", "f"));
        // list
        L.Object(TestUtil.getLongStringList(this));
        // array
        L.Object(TestUtil.getShortStringArr());
        // arrays
        double[][] doubles = {
                {1.2, 1.6, 1.7, 30, 33},
                {1.2, 1.6, 1.7, 30, 33},
                {1.2, 1.6, 1.7, 30, 33},
                {1.2, 1.6, 1.7, 30, 33}
        };
        L.Object(doubles);
        // sub class
        new User("name", "sex").log();  
    

结果如下：
