需求
比如说每个人都有一个小目标,每天看看自己的目标会更有动力,那么现在实现”一个亿”的小目标,我们让从点击我的Tab开始,
进入支付页面-钱包页面-零钱页面显示的金额都是¥100000000.00
结果
微信Android7.0.16版本,最后代码实现的效果如下:
准备工作
Root相关
- TWRP Recovery:一款强大的第三方recovery,有着官方Recovery无法做到的功能,安装Magisk Manager需要用到
- Magisk Manager:一款强大的刷Root工具,可以替代
SuperSU
进行root权限管理
如果用VirtualXposed或太极或其他虚拟环境的Xposed则可以不用Root,如果用Xposed Installer则需要Root权限,
关于这三者可看上篇文章:Xposed系列之Demo上手指南及源码解析(一)
反编译相关
- apktool:主要用于反编译APK查看资源文件
- dex2jar:反编译APK得到Java源代码Jar包
- jd-gui:一般配合
dex2jar
使用,将其反编译得到的jar包拖进gui方便查看源码 - jadx:功能强大的反编译工具,可以直接查看Java代码和资源文件等,同时支持查看Smali
推荐使用jadx工具反编译,如从微信官网下载的32位版本微信,默认都是会下载上面weixin7016android1700_arm64.apk
,
如果下载arm64版本则有些x86架构的模拟器不支持微信就不能正常使用了,所以用32位主要是为了方便在模拟器上调试
然后将下载下来的weixin7016android1700.apk
拖入JadxGUI中,反编译结果如下图:
并且我们还可以另存为Gradle项目,在Android Studio或IDEA中查看,操作入口如下:

adb命令
adb 命令可以参考https://github.com/xbdcc/CCommand, 这里简单介绍这里需要使用的:
adb shell dumpsys activity top > activity_top.txt
当然如果adb命令你已经很熟悉了想快捷输入也可以在环境变量中设置alisa
,
- 控制台中输入
vim ~/.bash_profile
- 在其中加入一行设置
adb shell dumpsys activity top > activity_top.txt
的别名为activity_top
,如下:
alias activity_top="adb shell dumpsys activity top > activity_top.txt"
- 然后按
esc
键,再输入:wq
回车退出并保存 - 再输入
source ~/.bash_profile
使环境变量生效 - 最后控制台直接输入
activity_top
回车就和刚刚一长串命令一样的效果了
该命令可以输出当前Activity信息,如命令抓取的零钱页面Activity的信息如下:

monitor
-
可以查看布局元素和trace信息,分析布局可以查看之前文章Android通过辅助功能实现抢微信红包原理简单介绍
-
,分析trace方法调用栈,例如下:
-
,生成生成html格式的trace,可以分析卡顿丢帧等问题,如果有打Trace也可以在上面看出来。可以在Chrome里打开查看,如下:
再介绍三种方便查找id值的方法
假如我们要查看id为dod
的值:
通过activity_top
查看
在里面找到元素对应的值,为十六进制值。如上面结果中有这样一行,可以看到id为’dod’的值为十六进制值7f091794
com.robinhood.ticker.TickerView{21299fb V.ED.... ........ 0,0-330,114 #7f091794 app:id/dod}
通过apk查看
可以把apk拖进AS中,在resources.arsc
下选择你要找的id,得到的值为十六进制
通过jadx查看
双击resources.arsc
,可以在里面搜索id,得到的值为十进制。如id为dod
的值为十进制值2131302292
Hook分析
通过activity_top
得知:
- 支付页面:com.tencent.mm/.plugin.mall.ui.MallIndexUI
- 钱包页面:com.tencent.mm/.plugin.mall.ui.MallWalletUI
- 零钱页面:com.tencent.mm/.plugin.wallet.balance.ui.WalletBalanceManagerUI
分析布局
- 首先打开支付页面我们通过monitor的
Dump View Hierarchy
,得知显示钱包的金额的控件id为dod
- 然后我们通过
activity_top
找到这个id的地方知道它其实是com.robinhood.ticker.TickerView
这个控件,
嗯这个一看就是不是腾讯的自定义View而是用的第三方库,Github上一搜,可以知道它用的是ticker这个库,
后面可以看到钱包页面和零钱页面显示金额的也是用的这个控件。
知道了这个库我们可以看下TickerView这个类的代码,这里再推荐一个Chrome插件octotree比较方便在GitHub网页上切换文件,
如下,可以看到这里有个setText方法,里面执行了columnManager.setText(targetText);
代码,而columnManager
最后执行了columnManager.draw(canvas, textPaint);
把文字绘制到Canvas上了,
setContentDescription(text);
设置了contentDescription的值,所以这就是我们能看到描述和显示金额的值一样,但是它的text属性值却为空的原因了。
分析支付页面MallIndexUI
- 首先我们观察到每次进入支付页面它的金额旁边是有个loading的,并且从钱包页面返回到支付页面也都会loading一下,那么可以猜想它可能是在onResume里面做了什么操作
(其实直接看它代码一下就能看出来,假设我们还没看代码先简单猜下)。那么我们看下它的onResume方法调用栈如下:看到了吗?里面主要就执行了
MallIndexBaseUI
(MallIndexUI的父类)的onResume
和自己的dbb
方法,这个时候如果你不想看源码继续分析的话其实就已经可以尝试Hook跑起来看看效果了,
本着保险起见我们还是先继续看看它的源码public final void dbb() { AppMethodBeat.i(66131); ac.i("MicorMsg.MallIndexUI", "updateBalanceNum"); ak akVar = new ak(); if (akVar.erV()) { this.uCo.setText((String) g.agR().agA().get(ah.a.USERINFO_WALLET_RELEAY_NAME_BALANCE_CONTENT_STRING_SYNC, (Object) getString(R.string.eex))); this.uCo.setVisibility(0); this.uDf.setVisibility(8); this.uDg.setVisibility(8); AppMethodBeat.o(66131); return; } if (akVar.erX()) { ac.i("MicorMsg.MallIndexUI", "show balance amount"); long longValue = ((Long) ((com.tencent.mm.plugin.wxpay.a.a) g.ad(com.tencent.mm.plugin.wxpay.a.a.class)).getWalletCacheStg().get(ah.a.USERINFO_NEW_BALANCE_LONG_SYNC, (Object) 0L)).longValue(); if (this.uDf != null) { nQ(akVar.erZ()); if (this.uDf.getVisibility() == 0) { this.uDf.setMoney(com.tencent.mm.wallet_core.ui.e.C(com.tencent.mm.wallet_core.ui.e.a(String.valueOf(longValue), "100", 2, RoundingMode.HALF_UP).doubleValue())); AppMethodBeat.o(66131); return; } } else { ac.w("MicorMsg.MallIndexUI", "moneyLoadingView is null"); } } AppMethodBeat.o(66131); }
可以看出ac.i应该就是打印的log方法,根据它的日志
updateBalanceNum
,可以知道这个方法主要是更新余额的,那么我们是不是可以手动拦截这个方法替换为自己设置的呢?我们来试试,
拿到方法的对象转为Activity,然后通过findViewById
找到显示金额的控件,通过反射拿到setText
并且调用赋值,或者通过XposedHelpers.callMethod(view, "setText", money)
private fun hookPayPage() { XposedHelpers.findAndHookMethod("com.tencent.mm.plugin.mall.ui.MallIndexUI", classLoader, "dbb", object : XC_MethodReplacement() { override fun replaceHookedMethod(param: MethodHookParam?): Any { param?.let { val activity = param.thisObject as Activity var view = activity.findViewById<View>(0x7f091794) //id:dod的id值为0x7f091794 val method = view.javaClass.getDeclaredMethod("setText", String::class.java) method.invoke(view, money) xlog("Hook method dbb of MallIndexUI class and set money.") } return "" } }) }
- 其实刚刚在
dbb
方法有这样一个方法this.uDf.setMoney
,通过方法名知道它是设置金额的,所以我们也可以从这里下手,该方法代码如下:public void setMoney(String str) { AppMethodBeat.i(71606); cc(str, false); AppMethodBeat.o(71606); }
再来看
cc
这个方法,第一个if它首先是判断了如果传进来的str
为null
则返回,第二个if在WcPayMoneyLoadingView
类里面我们可以看到this.BNi
只在setFirstMoney
方法里面赋值this.BNi = str;
,
在reset
方法里清空该值,并且进到bs
类里面可以看到isNullOrNil
方法如果this.BNi
值为null
或者字符串长度小于等于0才返回true,
所以这里其实是判断这个字段是否为空,如果不为空就直接setFirstMoney
,如果为空就setNewMoney
,和下面逻辑一致。public final void cc(String str, boolean z) { AppMethodBeat.i(71607); if (str == null) { AppMethodBeat.o(71607); return; } if (bs.isNullOrNil(this.BNi)) { setFirstMoney(str); if (z) { removeCallbacks(this.BNk); AppMethodBeat.o(71607); return; } } else { setNewMoney(str); } AppMethodBeat.o(71607); }
继续看
if (z)
这个判断,里面主要执行了removeCallbacks(this.BNk);
,而this.BNk
是一个Runnable对象如下,
根据日志show loading pb
知道这里显示了loading Progress,设置了它为可见的,最终其实可以找到它其实id为gxq
显示金额控件后面的Progresspublic Runnable BNk = new Runnable() { public final void run() { AppMethodBeat.i(71596); ac.i("MicroMsg.WcPayMoneyLoadingView", "show loading pb"); WcPayMoneyLoadingView.this.iIW.setVisibility(0); boolean unused = WcPayMoneyLoadingView.this.BNj = true; AppMethodBeat.o(71596); } };
所以我们可以Hook
cc
这个方法,在它执行前修改第一个参数值为你的金额’money`,如下:private fun hookPayPage2() { XposedHelpers.findAndHookMethod("com.tencent.mm.plugin.wallet_core.ui.view.WcPayMoneyLoadingView", classLoader, "cc", String::class.java, Boolean::class.java, object : XC_MethodHook() { override fun beforeHookedMethod(param: MethodHookParam?) { param?.let{ val view = param.thisObject as View param.args[0] = money } } }) }
分析钱包页面WalletBalanceManagerUI
- 前面分析支付页面知道
WcPayMoneyLoadingView
中有setFirstMoney
和setNewMoney
,其实我们就可以直接Hook替换这两个方法,
而且该方法通用三个页面都有效,如下:private fun hookMoney() { val hookClass = classLoader.loadClass(wechatMoneyLoadingView) ?: return XposedHelpers.findAndHookMethod(hookClass, "setFirstMoney", String::class.java, replaceStr) XposedHelpers.findAndHookMethod(hookClass, "setNewMoney", String::class.java, replaceStr) } private val replaceStr = object : XC_MethodHook() { override fun beforeHookedMethod(param: MethodHookParam?) { param?.let { val view = param.thisObject as View when(view.context.javaClass.name) { wechatWalletActivity -> param.args[0] = "¥$money" wechatPayActivity, wechatChangeActivity -> param.args[0] = money } } } }
分析零钱页面WalletBalanceManagerUI
- 首先我们看下
零钱页面WalletBalanceManagerUI
里面声明的对象,再根据View Hierarchy
我们知道AZo
是在TickerView
外面的WcPayMoneyLoadingView
,
继续看this.AZo.cc
,可以发现它调用的之前支付页面分析的WcPayMoneyLoadingView
中的tk
方法,所以我们可以直接Hook这个方法,如下:private fun hookChangePage() { XposedHelpers.findAndHookMethod("com.tencent.mm.plugin.wallet.balance.ui.WalletBalanceManagerUI", classLoader, "tk", Boolean::class.java, object : XC_MethodReplacement() { override fun replaceHookedMethod(param: MethodHookParam?): Any { param?.let { val activity = param.thisObject as Activity var view = activity.findViewById<View>(0x7f091794) //id:dod的id值为0x7f091794 XposedHelpers.callMethod(view, "setText", money) xlog("Hook method tk of WalletBalanceManagerUI class and set money.") } return "" } }) }
结语
其实分析的时候可能有点复杂,并且要善于用多种工具一起分析,但是最后实现的代码很简单,整理后代码如下:
class WechatHook : IXposedHookLoadPackage {
private val packageName = "com.tencent.mm"
private lateinit var classLoader: ClassLoader
private val wechatPayActivity = "com.tencent.mm.plugin.mall.ui.MallIndexUI"

"com.tencent.mm.plugin.wallet_core.ui.view.WcPayMoneyLoadingView"
private var money = "100000000.00"
override fun handleLoadPackage(lpparam: XC_LoadPackage.LoadPackageParam) {
if (packageName == lpparam.packageName) {
xlog("Load Wechat app.")
classLoader = lpparam.classLoader

}
