片段和Anko吐司的“接收器类型不匹配" [英] 'receiver type mismatch' with Fragment and Anko toast

问题描述

我正在尝试使用Jetbrains的Anko库在我的应用程序中轻松显示Android Toast消息.

I am trying to use Jetbrains' Anko library to easily display an Android toast message in my app.

这是相关的代码段:

val message : CharSequence = "Recycled: ${holder.taskEditText.text}"
(tasksFragment as Fragment).toast(text = message)

和错误:

Error:(80, 45) Unresolved reference. None of the following candidates is applicable because of receiver type mismatch:
public inline fun Fragment.toast(text: CharSequence): Unit defined in org.jetbrains.anko
public inline fun Fragment.toast(textResource: Int): Unit defined in org.jetbrains.anko
public fun Context.toast(text: CharSequence): Unit defined in org.jetbrains.anko
public fun Context.toast(textResource: Int): Unit defined in org.jetbrains.anko
public inline fun AnkoContext<*>.toast(text: CharSequence): Unit defined in org.jetbrains.anko
public inline fun AnkoContext<*>.toast(textResource: Int): Unit defined in org.jetbrains.anko

对于Kotlin来说，我还很陌生，并且一段时间以来一直在寻找解决方案.感谢所有帮助.

I am pretty new to Kotlin and have been searching for a solution to this issue for a while. All help is appreciated.

推荐答案

由于错误提示所有错误均不适用，因此您可能导入了与Android/Support Library定义的类不同的Fragment类.

Since the error says none are applicable you've probably imported a different Fragment class than the one defined by Android/Support Library.

检查您的进口.
