Xposed常用API
1.Hook变量
静态变量与实例变量:
- 静态变量(static):类被初始化,同步进行初始化
- 非静态变量:类被实例化(产生一个对象的时候),进行初始化
静态变量
final Class clazz = XposedHelpers.findClass("类名", classLoader);
XposedHelpers.setStaticIntField(clazz, "变量名", 999);
实例变量
final Class clazz = XposedHelpers.findClass("类名", classLoader);
XposedBridge.hookAllConstructors(clazz, new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
super.afterHookedMethod(param);
//param.thisObject获取当前所属的对象
Object ob = param.thisObject;
XposedHelpers.setIntField(ob,"变量名",9999);
}
});
2.Hook构造函数
无参构造函数
XposedHelpers.findAndHookConstructor("com.zj.wuaipojie.Demo", classLoader, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
super.beforeHookedMethod(param);
}
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
super.afterHookedMethod(param);
}
});
有参构造函数
XposedHelpers.findAndHookConstructor("com.zj.wuaipojie.Demo", classLoader, String.class, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
super.beforeHookedMethod(param);
}
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
super.afterHookedMethod(param);
}
});
3.Hook multiDex方法
XposedHelpers.findAndHookMethod(Application.class, "attach", Context.class, new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
ClassLoader cl= ((Context)param.args[0]).getClassLoader();
Class<?> hookclass=null;
try {
hookclass=cl.loadClass("类名");
}catch (Exception e){
Log.e("zj2595","未找到类",e);
return;
}
XposedHelpers.findAndHookMethod(hookclass, "方法名", new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
}
});
}
});
4.主动调用
静态方法:
Class clazz = XposedHelpers.findClass("类名",lpparam.classLoader);
XposedHelpers.callStaticMethod(clazz,"方法名",参数(非必须));
实例方法:
Class clazz = XposedHelpers.findClass("类名",lpparam.classLoader);
XposedHelpers.callMethod(clazz.newInstance(),"方法名",参数(非必须));
5.Hook内部类
内部类:类里还有一个类class
XposedHelpers.findAndHookMethod("com.zj.wuaipojie.Demo$InnerClass", lpparam.classLoader, "innerFunc",String.class, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
super.beforeHookedMethod(param);
}
});
6.反射大法
Class clazz = XposedHelpers.findClass("com.zj.wuaipojie.Demo", lpparam.classLoader);
XposedHelpers.findAndHookMethod("com.zj.wuaipojie.Demo$InnerClass", lpparam.classLoader, "innerFunc",String.class, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
super.beforeHookedMethod(param);
//第一步找到类
//找到方法,如果是私有方法就要setAccessible设置访问权限
//invoke主动调用或者set修改值(变量)
Class democlass = Class.forName("com.zj.wuaipojie.Demo",false,lpparam.classLoader);
Method demomethod = democlass.getDeclaredMethod("refl");
demomethod.setAccessible(true);
demomethod.invoke(clazz.newInstance());
}
});
7.遍历所有类下的所有方法
XposedHelpers.findAndHookMethod(ClassLoader.class, "loadClass", String.class, new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
super.afterHookedMethod(param);
Class clazz = (Class) param.getResult();
String clazzName = clazz.getName();
//排除非包名的类
if(clazzName.contains("com.zj.wuaipojie")){
Method[] mds = clazz.getDeclaredMethods();
for(int i =0;i<mds.length;i++){
final Method md = mds[i];
int mod = mds[i].getModifiers();
//去除抽象、native、接口方法
if(!Modifier.isAbstract(mod)
&& !Modifier.isNative(mod)
&&!Modifier.isAbstract(mod)){
XposedBridge.hookMethod(mds[i], new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
super.beforeHookedMethod(param);
Log.d("zj2595",md.toString());
}
});
}
}
}
}
});
8.Xposed妙用
字符串赋值定位:
XposedHelpers.findAndHookMethod("android.widget.TextView", lpparam.classLoader, "setText", CharSequence.class, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
super.beforeHookedMethod(param);
Log.d("zj2595",param.args[0].toString());
if(param.args[0].equals("已过期")){
printStackTrace();
}
}
});
private static void printStackTrace() {
Throwable ex = new Throwable();
StackTraceElement[] stackElements = ex.getStackTrace();
for (int i = 0; i < stackElements.length; i++) {
StackTraceElement element = stackElements[i];
Log.d("zj2595","at " + element.getClassName() + "." + element.getMethodName() + "(" + element.getFileName() + ":" + element.getLineNumber() + ")");
}
}
点击事件监听:
Class clazz = XposedHelpers.findClass("android.view.View", lpparam.classLoader);
XposedBridge.hookAllMethods(clazz, "performClick", new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
super.afterHookedMethod(param);
Object listenerInfoObject = XposedHelpers.getObjectField(param.thisObject, "mListenerInfo");
Object mOnClickListenerObject = XposedHelpers.getObjectField(listenerInfoObject, "mOnClickListener");
String callbackType = mOnClickListenerObject.getClass().getName();
Log.d("zj2595",callbackType);
}
});
改写布局:
XposedHelpers.findAndHookMethod("com.zj.wuaipojie.ui.ChallengeSixth", lpparam.classLoader,
"onCreate", Bundle.class, new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
super.afterHookedMethod(param);
View img = (View)XposedHelpers.callMethod(param.thisObject,
"findViewById", 0x7f0800de);
img.setVisibility(View.GONE);
}
});

五、答疑
提一嘴,我感觉肯定会有人问我的as怎么跟他的不一样,那是因为我用了一些插件。插件入口:左上角File->Settings->Plugins,在这里可以搜索并安装你想安装的插件,以下是我用的插件
