 In our previous post, we talked about the most basic ways to apply ArrayAdapter.

 If you have a question about layout.simple_list_item_1 while writing it this time, wouldn't there be layout.simple_list_item_2 as well?

 I wrote it to solve the curiosity.

import android.os.Bundle
import android.widget.ListView
import android.widget.SimpleAdapter
import androidx.appcompat.app.AppCompatActivity


class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_test)

        // List date to show in list view (for testing)
        val list = ArrayList<HashMap<String, String?>>()
        val item01 = HashMap<String, String?>()
        item01["key01"] = "list01"
        item01["key02"] = "contents01"
        list.add(item01)
        val item02 = HashMap<String, String?>()
        item02["key01"] = "list02"
        item02["key02"] = "contents02"
        list.add(item02)

        // STEP01. Declare the list view of the layout as a list view called mlistview
        val mListView = findViewById<ListView>(R.id.mListView)

        // STEP02. Settings From
        val from = arrayOf("key01", "key02")

        // STEP03. Settings To
        val to = intArrayOf(android.R.id.text1, android.R.id.text2)

        // STEP04. Call the default Array Adapter to apply to the List.
        val mAdapter = SimpleAdapter(this, list, android.R.layout.simple_list_item_2, from, to)

        // STEP05. Apply the Adapter to the list view.
        mListView.adapter = mAdapter
    }
}
