smali文件简要结构

————————————
注解、属性、方法
实例化过程 （class初始化、class实例化）
获取变量、赋值、调用方法传递参数过程
———————————属性

.class final synthetic Lcom/meituan/sankuai/erpboss/component/PickerDataManager$$Lambda$2;
.super Ljava/lang/Object;

# annotations
.annotation system Ldalvik/annotation/Signature;

# interfaces
.implements Lrx/functions/Action1;

# static fields
.field public static final CITY:I = 0x2

# instance fields
.field private

.field public mNameActivityUtil:Lcom/pitaya/findviewbyiddemo/NameActivityUtil;
    .annotation build Lcom/pitaya/findviewbyid_annotation/FindViewById;
        value = "com.pitaya.findviewbyiddemo.R.layout.activity_main"
    .end annotation
.end field


# direct methods
.method static constructor <clinit>()V   用于类class初始化 静态变量，静态代码块中代码在这个时候执行

.method private constructor <init>(Ljava/lang/String;ILandroid/content/Context;)V  用于实例化类先 调用父类构造函数 ——》自身中的属性字段被初始化 ——》自己在构造方法中的代码。
———————————
    mAllProvinces = getProvinceDatas(mAdministrativeRegionBean);

    invoke-direct {p0, v0}, Lcom/meituan/sankuai/erpboss/component/PickerDataManager;->getProvinceDatas(Lcom/meituan/sankuai/erpboss/location/bean/AdministrativeRegionBean;)Ljava/util/List;

    move-result-object v0

    iput-object v0, p0, Lcom/meituan/sankuai/erpboss/component/PickerDataManager;->mAllProvinces:Ljava/util/List;

存在多个构造函数时，每个构造函数都存在一份相同的公共执行流程。
