Trying to create a onClick function form a different activity with Kotlin












0















I've created a function in a different Kotlin class that I want to use with a button in my layout. The problem is that the layout can't find the function.
It has no problem to find the function in the MainActivity class.



I've added the new class as an activity in the manifest.



<activity android:name=".my_class">

    </activity>


I've extended activity



class my_class: Activity()


I've tried to change the .XML text



tools:context=".my_view"


I've added the onCreate function to the class



override fun onCreate(savedInstanceState: Bundle?)

    {

        super.onCreate(savedInstanceState)

        setContentView(R.layout.activity_main)



    }


but the layout is still not able to find the function in the other class, only when I write it in the MainActivity class.

          1 I tried to upgrade a yummy sandwich made of two test slices (@JsonTest and @JdbcTest in my case, crunchy test code in between) adding spring boot 2.1 flavour to it. But it seems it was not much of a success. I cannot annotate my tests with many @...Test since they are now each bringing their own XxxTestContextBootstrapper. It used to work when they all used same SpringBootTestContextBootstrapper. @RunWith(SpringRunner.class) @JdbcTest @JsonTest public class Test { @Test public void test() { System.out.printn("Hello, World !"); } } The error I get from BootstrapUtils is illegalStateException : Configuration error: found multiple declarations of @BootstrapWith for test class I understand I might be doing something wrong here but is there an easy way I could load both Json and Jdbc contex...
