我挂接的是Android框架本身，而不是一个特定的应用程序，这是我的代码：

public void handleLoadPackage(XC_LoadPackage.LoadPackageParam lpparam) throws Throwable {
        
        if (lpparam == null||lpparam.packageName == null || lpparam.processName == null)
            return;

        if (lpparam.packageName.equals("android")) {
            XposedBridge.log("Hooked into Android framework.");

            if (!sInitialized) {
                sInitialized = true;
                hookSetVisibility(lpparam);
            }
        }
    }

    private void hookSetVisibility(XC_LoadPackage.LoadPackageParam lpparam) {

        final Class<?> mViewGroup = XposedHelpers.findClass("android.widget.TextView", lpparam.classLoader);
        for (final Method method : mViewGroup.getDeclaredMethods()) {
            if (true == Modifier.isAbstract(method.getModifiers())) {
                XposedBridge.log("skip abstract:" + method.getName());
                continue;
            }
            XposedBridge.log("----" + method.getName());
            XposedBridge.hookMethod(method, methodHook);
        }
    }

    final StringBuilder sb = new StringBuilder();
    XC_MethodHook methodHook = new XC_MethodHook() {
        @Override
        protected void beforeHookedMethod(XC_MethodHook.MethodHookParam param) throws Throwable {

            XposedBridge.log("before hook log");
        }

        @Override
        protected void afterHookedMethod(XC_MethodHook.MethodHookParam param) throws Throwable {
            //param.setResult(false);
            XposedBridge.log("after hook log");       
        }
    };

这个模块确实很好地打印了所有类的方法名，就像在android framework中看到的那样，但是BeforeHookedMethod和afterHookMethod从来没有被调用过。
