Kotlin

Question

我有一个只有一个功能的界面，它工作正常。然后我添加了第二个函数，我想用它来发送相同的数组但发送到不同的 activity，但是在主 activity 中我收到以下错误：没有为参数传递值 'PatDischargeBtnDelegate'。这是我的代码：

界面

interface PatDataCommentDelegate {
    fun patDataCommentBtnClicked(ptdata: PatData)
    fun dischargePatientBtnClicked(ptdata: PatData)
}

适配器

class PatDataAdapter(val ptdata: ArrayList<PatData>, val patDataBtnDelegate: PatDataCommentDelegate,
                     val patDischargeBtnDelegate: PatDataCommentDelegate) : 
RecyclerView.Adapter<PatDataAdapter.ViewHolder>() { 
......


       commentImage?.setOnClickListener {
            patDataBtnDelegate.patDataCommentBtnClicked(ptdata)
        }

        dischargePatImg?.setOnClickListener{
            patDischargeBtnDelegate.dischargePatientBtnClicked(ptdata)
        }

主要Activity

class PatDataActivity : AppCompatActivity(), PatDataCommentDelegate {
....

patDataFromAdapter = PatDataAdapter(ptdatas, this) //I get the error here


 override fun patDataCommentBtnClicked(ptdata: PatData) {
        val commentDataActivity = Intent(this, CommentsActivity::class.java)
        commentDataActivity.putExtra(DOCUMENT_ID, ptdata.documentId)
        commentDataActivity.putExtra(USER_ID, userId)
        commentDataActivity.putExtra(PTNAME, ptdata.ptName)
        commentDataActivity.putExtra(FIN, ptdata.fin)
        commentDataActivity.putExtra(ROOM, ptdata.room)
        commentDataActivity.putExtra(HOSP, ptdata.hosp)
        startActivity(commentDataActivity)
    }

    override fun dischargePatientBtnClicked(ptdata: PatData) {
        val dischargePatientActivity = Intent(this, DischargeActivity::class.java)
        dischargePatientActivity.putExtra(DOCUMENT_ID, ptdata.documentId)
        dischargePatientActivity.putExtra(USER_ID, userId)
        dischargePatientActivity.putExtra(PTNAME, ptdata.ptName)
        dischargePatientActivity.putExtra(FIN, ptdata.fin)
        dischargePatientActivity.putExtra(ROOM, ptdata.room)
        dischargePatientActivity.putExtra(HOSP, ptdata.hosp)
        startActivity(dischargePatientActivity)
    }

我不确定我遗漏了什么，非常感谢您的帮助。谢谢！

Answer 1

问题出在第三个参数中。

class PatDataAdapter(
    val ptdata: ArrayList<PatData>, 
    val patDataBtnDelegate: PatDataCommentDelegate,
    val patDischargeBtnDelegate: PatDataCommentDelegate // you don't need this one.
) : RecyclerView.Adapter<PatDataAdapter.ViewHolder>() {

这应该有效：

class PatDataAdapter(val ptdata: ArrayList<PatData>, val patDataBtnDelegate: PatDataCommentDelegate) : 
RecyclerView.Adapter<PatDataAdapter.ViewHolder>() { 


   commentImage?.setOnClickListener {
        patDataBtnDelegate.patDataCommentBtnClicked(ptdata)
    }

    dischargePatImg?.setOnClickListener{
        patDataBtnDelegate.dischargePatientBtnClicked(ptdata)
    }

您只需要引用接口 PatDataCommentDelegate 本身，而不是分别引用每个方法。
