接上篇继续说Xposed第一课(微信篇) hook含有多个参数的方法

今天来尝试看看修改聊天列表界面的一些消息，首先cmd 输入adb shell dumpsys activity top 接下来上图

有时候仔细留心你会发现一些有用的东西com.tencent.mm.ui.chatting.ChattingUI$a 这个就是我们此次的目标了

public class ChattingUI$a extends u implements e, com.tencent.mm.plugin.messenger.foundation.a.a.f.a, com.tencent.mm.sdk.e.j.a, b, p

哟哟切克闹，这次明确目标从继承类和实现类慢慢入手观看，你会发现com.tencent.mm.ui.u是fragment，所以按照开发习惯会在onCreateView方法里面进行初始化操作

之后关联到了com.tencent.mm.ui.p这个抽象类

这里有很多有意思的操作，也记录下来，说不定马上就用得到了~

可能会有人疑问，你怎么就定位那这里来了？看得头晕~~
我先上ChattingUI$a的代码

public void onCreate(Bundle bundle) {
        com.tencent.mm.sdk.platformtools.w.i("MicroMsg.ChattingUI", "dktask FragmentonCreate:%s#0x%x task:%s hc:%d", new Object[]{thisActivity().getClass().getSimpleName(), Integer.valueOf(thisActivity().hashCode()), com.tencent.mm.sdk.platformtools.bh.fE(thisActivity()), Integer.valueOf(hashCode())});
        cuW();
        f fVar = this.yRU;
        if (fVar.cvH()) {
            fVar.yUY = new com.tencent.mm.ui.q();
            Object obj = fVar.yUY;
            u cuH = fVar.ejx.cuH();
            obj.yqI = cuH;
            obj.yqJ = new com.tencent.mm.ui.b.b(cuH.thisActivity(), obj);
            fVar.ejx.cuH().setActivityController(fVar.yUY);
        }
        if (this.mController != null) {
            this.mController.ak(3, true);
        }
        super.onCreate(bundle);
    }

里面关联到了new com.tencent.mm.ui.q() 一般这样的情况我会点进去看看这个类里面有些啥

结果找到了这个

protected final void dealContentView(View view) {
        if (this.yqI != null) {
            this.yqI.dealContentView(view);
        }
    }

眼熟吧，刚刚在截图里面出现过，在继续跟下去 就到了com.tencent.mm.ui.p 这就是他们的三角恋关系

接下來上代碼

 /**
     * 微信聊天界面
     *
     * @param applicationContext
     * @param classLoader
     */
    private void hookWxChatUI(final Context applicationContext, final ClassLoader classLoader) {
        final Class<?> classIfExists = XposedHelpers.findClassIfExists("com.tencent.mm.ui.chatting.ChattingUI$a", classLoader);
        if (classIfExists == null) return;
        XposedHelpers.findAndHookMethod(classIfExists,
                "onResume",
                new XC_MethodHook() {
                    @Override
                    protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
                        super.beforeHookedMethod(param);
                        XposedHelpers.findAndHookMethod(classIfExists, "cuO", new XC_MethodHook() {
                            @Override
                            protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
                                super.beforeHookedMethod(param);
                                Field ySc = param.thisObject.getClass().getDeclaredField("ySc");
                                ySc.setAccessible(true);
                                ListView listView = (ListView) ySc.get(param.thisObject);
                                ListAdapter adapter = listView.getAdapter();
                                int count = adapter.getCount();
                                Log.e("Demo: hookWxChatUI->", "listview has " + count + " child");
                                for (int i = 0; i < count; i++) {
                                    Object s = adapter.getItem(i);
                                    Log.e("Demo: hookWxChatUI->", "item data -> " + JSONObject.toJSONString(s));
                                }
                            }
                        });
                    }
                });
    }

偷个懒，只到这一步，我想你有了listview对象了基本可以随意修改了，后期会进行完善，实现撤回消息展示
