How do I remove lines between ListViews on Android using Kotlin?



This example demonstrates how to remove lines between ListViews on Android 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.

Example

<?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:paddingStart="4dp"    tools:context=".MainActivity"> <ListView    android:id="@+id/listView"    android:layout_width="wrap_content"    android:layout_height="match_parent"/> </RelativeLayout>

Step 3 − Add the following code to src/MainActivity.kt

import android.os.Bundle import android.widget.ArrayAdapter import android.widget.ListView import androidx.appcompat.app.AppCompatActivity class MainActivity : AppCompatActivity() {    lateinit var listView: ListView    var mobilePhones = arrayOf("Samsung", "Iphone", "Nokia", "Alcatel", "Blackberry", "Oppo", "Sony")    override fun onCreate(savedInstanceState: Bundle?) {       super.onCreate(savedInstanceState)       setContentView(R.layout.activity_main)       title = "KotlinApp"       listView = findViewById(R.id.listView)       val adapter: ArrayAdapter<Any?> = ArrayAdapter(this, android.R.layout.simple_list_item_1, android.R.id.text1, mobilePhones)       listView.adapter = adapter       listView.divider = null    } }

Step 4 − 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="com.example.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
