如何在onBindViewHolder中调用Context和Intent对象 [英] How to call Context and Intent objects inside onBindViewHolder

问题描述

我想在RecyclerView中打开一个新的Activity，但是无法在其中创建Intent对象.

I want to open a new Activity within RecyclerView, but I can't create an Intent object in there.

val intent1 = Intent(this,Main2Activity::class.java)   
startActivity(intent1) 

Android Studio警告Intent不是Context.如何仍然在RecyclerView

Android Studio warns about Intent not being a Context. How can I still open a new Activity inside the RecyclerView

我也尝试了下面的代码，它给出了"startActivity(intent)"行给出了错误，类型不匹配，必需的上下文，找到了Intent".

I tried also the code below,it gives "startActivity(intent)" line gives error, "type mismatch, required Context, found Intent".

此外，"this @ MainActivity"也会给出"unresolved reference @ MainActivity"错误.

Plus, also "this@MainActivity" gives "unresolved reference@MainActivity" error.

  override fun onBindViewHolder(holder: Main_Menu_Holder, position: Int) {
        var currentview = alldata.get(position)

    }

推荐答案

您正在呼叫this，这是您的RecyclerView的onBindViewHolder.您必须使用View调用Context:

You are calling this which is your RecyclerView's onBindViewHolder. You have to call the Context using View:

  override fun onBindViewHolder(holder: Main_Menu_Holder, position: Int, v:View) {
        val intent = Intent(v.context, Main2activity::class.java)
        startActivity(intent) 
}
