How to initialize context in RecyclerView Adapter?-CodePudding

I have an annoying problem I wanted to use custom dialog in recycler view adapter but I need a context for builder and I wrote that but I can't initialized that. I looked up Internet but I can't find anything. Is anyone can help me? Thank you and have a good codes :)

private lateinit var context: Context

1- From here you can pass Context like i am sending myContext From Activity/Faragment

        binding.rvIssues.layoutManager =
        LinearLayoutManager(myContext, RecyclerView.VERTICAL, false)
        val adapterIssue = AdapterIssues(myContext, messagesList)
        binding.rvIssues.adapter = adapterIssue

2 - In Adapter you can put keyWord var to globalise the scope of context and can be use any where in Adapter

class AdapterIssues(
var context: Context,
var messagesList: ArrayList<ResourceModel>,
var listener: SetOnIssueItemClickListener) :
RecyclerView.Adapter<AdapterIssues.ViewHolder>() {}

3- you don't need to put in adapter like

private lateinit var context: Context

CodePudding user response：

It would be great if you provide some of your code but, You could pass the context via your adapter constructor, something like this.

In Adapter you could write:

class MyAdapter(private val context: Context) : RecyclerView.Adapter<MyAdapter.ViewHolder>() {

    private lateinit var mContext: Context

    fun doSomething() {
        mContext = context
    }
}

In your Activity/Fragment:

private fun bindAdapter() {
    val adapter = MyAdapter(context = this)  // Use requireActivity() for fragments
}

Hope this help!!!
