The main idea is to use view.setBackgroundColor(getColor(R.color.colorAccent))
to the selected view (list item). Let’s see a complete example.
- use this xml code in
res/layout/activity_main.xml
.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="8dp"
tools:context=".MainActivity">
<ListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
- use this Kotlin code in
src/MainActivity.kt
.
import android.os.Build
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.widget.ArrayAdapter
import android.widget.ListView
class MainActivity : AppCompatActivity() {
var operatingSystem: Array<String> = arrayOf("Android", "IPhone", "WindowsMobile", "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X")
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
title = "KotlinApp"
val listView: ListView = findViewById(R.id.listView)
val adapter = ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, operatingSystem)
listView.adapter = adapter
listView.setOnItemClickListener { _, view, _, _ ->
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
view.setBackgroundColor(getColor(R.color.colorAccent))
}
}
}
}
Run the application. When you touch / tap / press on a list item its background color will change. That’s it. If you know somebody need this post, share it with him/her via Facebook / twitter / whatsapp / reddit / email / .. etc.
