kotlin中使用匿名内部类

1.常规的方式实现匿名内部类

写法1：

 mCamera?.autoFocus(object : Camera.AutoFocusCallback  {  //其中的object是Kotlin默认的内部关键字不可修改
            override fun onAutoFocus(success: Boolean, camera: Camera?) {
                TODO("not implemented") //To change body of created functions use File
            }
        })

写法2：

 mCamera?.autoFocus(Camera.AutoFocusCallback { success, camera ->
            {
                TODO("not implemented") //To change body of created functions use File
            }
        })

2.lambda 表达式版本的匿名内部类

 mCamera?.autoFocus({ success, camera ->
            run {
               TODO("not implemented") //To change body of created functions use File
            }
        })
