我试图在Circle CI上运行构建,但是在android kotlin中遇到了这个模棱两可的checkstyle错误,我不知道为什么会这样,以下是错误信息:

  

/home/circleci/repo/app/src/main/java/com/andela/mrm/util/ConvergeUIUtils.kt:   (12、23):导入冲突,导入名称“ Toast”含糊不清e:   /home/circleci/repo/app/src/main/java/com/andela/mrm/util/ConvergeUIUtils.kt:   (14、23):导入冲突,导入名称“ Toast”不明确

下面是ConvergeUIUtils.kt文件:

import android.content.Context
import android.graphics.Color
import android.graphics.PorterDuff
import android.support.constraint.ConstraintLayout
import android.support.design.widget.Snackbar
import android.support.v4.content.ContextCompat

import android.view.View
import android.widget.TextView
import android.widget.Toast
import com.andela.mrm.R

    }

    companion object {
        /**

        fun showSnackBar(context: Context, view: View, string: String) {
            val snackbar = Snackbar.make(view, string, Snackbar.LENGTH_LONG)
            val snackbarView = snackbar.view
            snackbarView.setPadding(10, 10, 10, 12)
            if (string.contains("extended")) {
                snackbarView.setBackgroundColor(ContextCompat.getColor(context, R.color.waiting_color))
            } else {
                snackbarView.setBackgroundColor(ContextCompat.getColor(context,
                        R.color.colorPrimaryDark))
            }
            snackbar.show()
        }

        /**
         * @param context the view context.
         * @param string the message of the toast.
         */

        fun showToast(context: Context, string: String) {
            val toast = Toast.makeText(context, string, Toast.LENGTH_LONG)
            toast.setGravity(Gravity.BOTTOM or Gravity.LEFT, 50, 50)
            val view = toast.view

            if (string.isNullOrBlank()) {

                view.setBackgroundResource(R.drawable.notification_success_img)
                toast.show()
            } else {

                if (string.contains("extended")) {
                    view.background.setColorFilter(ContextCompat.getColor(context, R.color.waiting_color),
                            PorterDuff.Mode.SRC_IN)
                    val text = view.findViewById<TextView>(android.R.id.message)
                    text.setTextColor(Color.WHITE)
                } else {
                    view.background.setColorFilter(ContextCompat.getColor(context,

                text.setTextColor(Color.WHITE)
                toast.show()
            }

        }


        /**
         * set background color for free time button.
         *

        fun setButtonColor(context: Context, freeDisplay: ConstraintLayout) {
            val normalDrawable = context.getDrawable(R.drawable.btn_room_extra_time)
            normalDrawable!!.setColorFilter(-0x1, PorterDuff.Mode.SRC_ATOP)
            freeDisplay.background = normalDrawable
        }

    }
}

如何克服这种checkstyle错误?

您的导入具有多个名为Toast的类。

Kotlin支持导入别名:https://kotlinlang.org/docs/reference/packages.html

import android.widget.Toast as WToast
