Open u201701 opened 5 years ago

u201701 commented 5 years ago

With the following source code, I get an IDE Error when I open the Anko Layout Preview tool window in Android Studio 3.3.1 with Kotlin plugin version: 1.3.21, Anko version set to 0.10.8 in project build.gradle and implementation "org.jetbrains.anko:anko:$anko_version" added to app build.gradle

package com.foobar.deleteme

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import org.jetbrains.anko.*

class MainActivityUI : AnkoComponent < MainActivity > {
    override fun createView(ui: AnkoContext<MainActivity>) = ui.apply {
        verticalLayout {
            button("bar")
        }
    }.view
}

class MainActivity : AppCompatActivity() {
    override fun onCreate(bundle: Bundle?) {
        super.onCreate(bundle)
        MainActivityUI().setContentView(this)
    }
}

same problem with Intellij idea Ultimate 18.3.5 with Kotlin plugin version: 1.3.21 and ext.anko_version = '0.10.8'

ABStepanov commented 5 years ago

I deleted Android Studio 3.3.2 and installed AS 3.2 (with kotlon 1.2.71 included) + " ext.anko_version＝'0.10.7' " in gradle file. After that, everything worked.

@ABStepanov , that did not worked on my case, just downgraded everything but no progress. Blocked by this issue since my project was built with anko layouts and unable implement design changes without preview. :(
