Xposed Ktx

Xposed kotlin extension.

Getting start

Step 1. Add the JitPack repository to your build file

allprojects {
  repositories {
      ...
      maven { url 'https://jitpack.io' }
   }
}

Step 2. Add the dependency

dependencies {
    implementation 'com.github.ikws4:xposed-ktx:latest-version'
}

Hook method

Use className(String) to hook method.

val className = "android.app.Activity"
className.hookMethod(classLoder, "onCreate", Bundle::class.java,
    beforeHookedMethod = { param ->
        // Do something
    },
    afterHookedMethod = { param ->
        // Do something
    })
    
// if you just use afterHookedMethod, you can do this

Activity::class.java.hookMethod("onCreate", Bundle::class.java) { param ->
     // Do something
}

Use class to hook method, then you can use 'this' to get Activity instance.

Activity::class.java.hookMethod("onCreate", Bundle::class.java, 
    beforeHookedMethod = { param ->
        // for example
        Toast.makeText(this, "I'm a toast", Toast.LENGHT_SHORT).show()
    },
    afterHookedMethod = { param ->
        // Do something
    })

Replace method

Activity::class.java.replaceMethod("onCreate", Bundle::class.java){ param ->
      // `this` is the Activity instance
}

// or

val className = "android.app.Activity"
className.replaceMethod(classLoder, "onCreate", Bundle::class.java){ param ->
      // Do something
}

Hook constructor

TextView::class.java.hookConstructor(Context::class.java,
     beforeHookedMethod = { param ->
          // Do something
          // 'this' is the TextView instance
     },
     afterHookedMethod = { param ->
         // Do something
     })

// or

val className = "android.widget.TextView"
className.hookConstructor(classLoader,Context::class.java,
     beforeHookedMethod = { param ->
         // Do something
     },
     afterHookedMethod = { param ->
         // Do something
     })

Replace constructor

TextView::class.java.replaceConstructor(Context::class.java) { param ->
     // 'this' is the TextView instance
     // Do something
}

// or

val className = "android.widget.TextView"
className.replaceConstructor(classLoader,Context::class.java) { param ->
     // Do something
}
