Kotlin android extensions plugin cant parse my layouts

dsvoronin · March 19, 2015, 6:03pm

Really like this feature, but can't make it work in my project.

alots of compiler errors, but only 3 different types

Error:Unresolved reference: include - not supported?
Error:Redeclaration: drawer_layout - i can handle it, my fault
Error:Unresolved reference: ViewStub - not supported?

what can i do with it?

yoavst · March 19, 2015, 6:28pm

Same for me, plugin installed, classpath was added.

Error:(8, 8) Unresolved reference: kotlinx

yanex · March 19, 2015, 6:57pm

Could you please provide an XML file with <include> tags which can't be parsed? I've tried to use <include>, and it works as should.

By the way, what IDEA/Android Studio version are you using?

dsvoronin · March 19, 2015, 7:01pm

Yeah, sorry:

Android Studio 1.1.0

I have multiple layouts with includes, for example:

<?xml version=“1.0” encoding=“utf-8”?>
<my.package.BetterViewAnimator
  android:id=“@id/switcher”
  xmlns:android=“http://schemas.android.com/apk/res/android”
  android:layout_width=“match_parent”
  android:layout_height=“match_parent”
  >

  <android.support.v7.widget.RecyclerView
  android:id=“@+id/list”
  android:layout_width=“match_parent”
  android:layout_height=“match_parent”
  />

</my.package.BetterViewAnimator>

I dont have any include Latest android studio beta

Is Kotlin configured in the Android project? You can test it with: Tools -> Kotlin -> Configure Kotlin in Project.

yanex · March 19, 2015, 7:52pm

<include> tags with ids are not supported yet, sorry. It will be fixed in near future.

yoavst · March 19, 2015, 8:01pm

I see! Please try to move buildscript Kotlin dependencies to the app/build.gradle file (https://gist.github.com/yanex/573f2ff27f2ee5604834). It solved the compilation problem on my test project with these build.gradle files.

hzsweers · March 19, 2015, 10:10pm

I was experiencing the same problem, moving the buildscript configuration to the same build.gradle file resolved it for me. Just out of curiosity, why is this necessary?

0leGG · March 20, 2015, 3:02am

Moving gradle dependencies to app/build.gradle helped me to get rid of import errors, while I'm still unable to get code work. I've got plenty of errors like this:

Error:(26, 9) Unresolved reference. None of the following candidates is applicable because of receiver type mismatch:
internal val android.app.Fragment.salaryEdit: android.widget.EditText! defined in kotlinx.android.synthetic.fragment_settings
internal val android.app.Activity.salaryEdit: android.widget.EditText! defined in kotlinx.android.synthetic.fragment_settings

Seems that plugin generates layout bindings only for core android classes like android.app.Activity and android.app.Fragment, while I'm using replacements from support library: android.support.v7.app.ActionBarActivity and android.support.v4.app.Fragment, which are not always subclasses of core classes

hzsweers · March 20, 2015, 4:28am

It works fine for me in ActionBarActivity

0leGG · March 20, 2015, 4:32am

Yes, it should work well with ActionBarActivity, because it's subclass of Activity; but Fragment from support library doesn't subclass android.app.Fragment, so all fragments derived from android.support.v4.app.Fragment won't resolve views.

yoavst · March 20, 2015, 7:24am

Why does it works?

yanex · March 20, 2015, 8:31am

We decided not to support android.support.v4.app.Fragment because it is useful only for Android 2.3. You can use synthetic properties for View receiver (getView().textView), if you import kotlinx.android.synthetic.fragment_settings.view.*. However, properties for Views are not cached.

hzsweers · March 20, 2015, 9:00am

> it is useful only for Android 2.3.

This is completely untrue. Ever used a ViewPager? If you want it to work with native fragments, you have to import a completely separate support library (v13). Not to mention, the v13 library doesn’t support nested fragments, so not using the support fragments would mean forfeting that functionality (at least as of Aug. 2014)

The support libraries have become integral enough to the point where many developers simply just use the support versions of core components by default in their day-to-day development. These often have more fixes for existing bugs on older versions as well, and in some cases support newer features.

yoavst · March 20, 2015, 9:03am

I'm agree. Does the apk contains all the extenstion methods, or unused get dropped? because if they get dropped you can add it without problem. If not, you can create same code but kotlin-android-extenstions-support

pawegio · March 20, 2015, 9:23am

+1

It is impossible not to use support libraries right now.

yanex · March 20, 2015, 9:24am

Ok, that's a good argument.

0leGG · March 23, 2015, 3:45pm

Are you planning to add support library support in next release? (Or even push a quick-fix in M11 update?)
