Smali语法学习六

#回顾 语法学习五中就有以下的数据定义：

move v0,p1                                         #赋值，v0=v1
const/4 v1,0x1                                    #定义常量，v1=1
const-string v2,"MainActivity"             #定义常量字符串，v2="MainActivity"
.local v1,"b1":Z                                   #定义局部变量，寄存器声明

#数据定义DEMO java代码：

private void test(){
    int a = 1;
    int b = 7;
    int c = 254;
    int d = 2345;
    int d1 = 65538;
    long e = 12435465657677L;
    float f = 123235409234.09097945F
    double g = 111343333454999999999.912384376;
}

#数据定义格式 const/4 vA,#+B 将数组扩展为32位后赋给寄存器vA
const/16 vAA,#+BBBB
const vAA,#+BBBBBBBB 将数组赋给寄存器vAA
const-wide/16 vAA,#+BBBBB 将数值扩展为64 位后赋给寄存器vA
const-string vAA,string@BBBB 将字符串索引构造一个字符串并赋给vAA
const-class vAA,type@BBBB 经过类型索引获取一个类的引用并赋给vAA
