How to add a footer in Android ListView using Kotlin?
This example demonstrates how to add a footer in Android ListView using Kotlin
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
Step 2 − Add the following code to 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="4dp" tools:context=".MainActivity"> <ListView android:id="@+id/listView" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true"> </ListView> </RelativeLayout>
Step 3 − Add the following code to src/MainActivity.kt
import android.os.Bundle
import android.view.ViewGroup
import android.widget.ArrayAdapter
import android.widget.ListView
import androidx.appcompat.app.AppCompatActivity
import java.util.*
class MainActivity : AppCompatActivity() {
private lateinit var listView: ListView
var country = arrayOf(
"India",
"Australia",
"South Africa",
"North America",
"South America",
"Iceland",
"GreenLand"
)
private lateinit var listString: List>String<
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
title = "KotlinApp"
listView = findViewById(R.id.listView)
listString = ArrayList(mutableListOf(*country))
val adapter = ArrayAdapter(this,
android.R.layout.simple_list_item_1, listString)
val layoutInflater = layoutInflater
val footer = layoutInflater.inflate(R.layout.listview_footer, listView, false) as ViewGroup
listView.addFooterView(footer)
listView.adapter = adapter
}
}Step 4 − Create a new Layout Resourse file and add the following code
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TextView android:id="@+id/textView" android:layout_width="match_parent" android:layout_height="wrap_content" android:padding="16sp" android:text="Footer: End of the ListView!" android:textAppearance="?android:attr/textAppearanceLarge" /> </LinearLayout>
Step 5 − Add the following code to androidManifest.xml
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="app.com.q11"> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest>
Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click the Run icon
from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen.
