    that generic type is used for setting adapters only

    Copy code
    public void setAdapter(ArrayAdapter<T> adapter) {
        filterSelectionList.setAdapter(adapter);
    }

    @martynas: in that case you can probably extract the type argument in some static function, instead of having it on a whole class

    I guess the way around it is to declare a class with specific type in it such as 
    class MyAwesomeTextView : CustomTextView<SomeType>

    @adeln: how would that look?

    I would try @adeln solution if generic type is not used to often

    it’s just that single class which is used in that one fragment with 5 views

    @martynas: To be clear, having a generic type of Custom View in XML works in Java?
  • m

    martynas

    09/30/2015, 9:55 AM
    yes.
    Copy code
    @InjectView(R.id.filter_item_color)
    FilterElement<ItemColor> itemColor;

    then it’s used to retrieve selections, setting adapters and so on.

    @martynas: oh, I don't think you even need to make it static: http://paste2.org/1kP2Xm8w

    Ok, thanks, I’ll try it out

    if you want to enforce some strictness over what kind of <T> is passed, you can force the compiler to do the checks for you with some trickery http://paste2.org/XbzEKz7b

    anybody had any problems with proguard and kotlin?
  • m

    martynas

    09/30/2015, 1:13 PM
    For some reason proguard removes almost all kotlin classes
  • m

    martynas

    09/30/2015, 1:15 PM
    or (not related to proguard) jUnit test compilation fails first time when compiling :`application:compileDebugUnitTestJavaWithJavac` with errors, that kotlin classes were not found.

    I have:
    Copy code
    -keep class kotlin.dom.** { public *; }
-dontwarn kotlin.dom.**

    @pawegio: does your class names match file names?
  • p

    pawegio

    09/30/2015, 1:48 PM
    in that project yes, all

    at least in Java you can perform an unchecked cast on the view and continue as normal. seems like this should be allowed in kotlin
  • e

    Eugenio

    09/30/2015, 2:26 PM
    I think you can do 
    x as Class
  • e

    Eugenio

    09/30/2015, 2:27 PM
    or worst case you do 
    if (x is Class)
    and then it will be smart casted

    Do you use 
    kotlin-android-extensions
    ? I get 1010 warning messages at compile time 
    No cast needed

    No By the way 
    kotlin-android-extensions
    do not cache views when findById is called

    good to know
