This example demonstrates how to use search functionality in custom listview in 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.
<?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"> <EditText android:id="@+id/etSearch" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="Search here" /> <ListView android:id="@+id/listView" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_below="@id/etSearch" /> </RelativeLayout>
Step 3 − Add the following code to src/MainActivity.kt
import android.os.Bundle import android.text.Editable import android.text.TextWatcher import android.widget.ArrayAdapter import android.widget.EditText import android.widget.ListView import androidx.appcompat.app.AppCompatActivity class MainActivity : AppCompatActivity() { lateinit var listView: ListView var months: ArrayList<String> = ArrayList() var arrayAdapter: ArrayAdapter<String>? = null lateinit var etSearch: EditText override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) title = "KotlinApp" listView = findViewById(R.id.listView) etSearch = findViewById(R.id.etSearch) months.add("January") months.add("February") months.add("March") months.add("April") months.add("May") months.add("June") months.add("July") months.add("August") months.add("September") months.add("October") months.add("November") months.add("December") arrayAdapter = ArrayAdapter(this, android.R.layout.simple_list_item_1, android.R.id.text1, months) listView.adapter = arrayAdapter etSearch.addTextChangedListener(object : TextWatcher { override fun beforeTextChanged(s: CharSequence, start: Int, count: Int, after: Int) {} override fun onTextChanged(s: CharSequence, start: Int, before: Int, count: Int) { arrayAdapter!!.filter.filter(s) } override fun afterTextChanged(s: Editable) {} }) } }

<?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.
