Android Studio 3.1.4中针对Kotlin的代码建议会产生致命错误。
示例应用程序如下（所有其他内容均为默认值）：
activity_main.xml
<android.support.constraint.ConstraintLayout ...>
<TextView .../>
<Button ...
android:onClick="clr" />
</android.support.constraint.ConstraintLayout>
MainActivity.kt（（仅为默认值））
，因此xml上的onClick显示建议“在MainActivity中创建clr（View）”。但是，在单击建议时，会弹出IDE致命错误

现在就可以在MainActivity.kt中手动创建单击功能。希望可以解决此问题
