How to add Google Search Functionality in Kotlin?



This example demonstrates how to add Google Search Functionality in 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="16dp"    tools:context=".MainActivity">    <TextView       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:layout_centerHorizontal="true"       android:layout_marginTop="50dp"       android:text="Tutorials Point"       android:textAlignment="center"       android:textColor="@android:color/holo_green_dark"       android:textSize="32sp"       android:textStyle="bold" />    <ImageView       android:layout_width="match_parent"       android:layout_height="200dp"       android:layout_above="@id/editText"       android:layout_marginBottom="30dp"       android:src="@drawable/google" />    <EditText       android:id="@+id/editText"       android:layout_width="match_parent"       android:layout_height="wrap_content"       android:layout_centerInParent="true" />    <Button       android:id="@+id/btnSearch"       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:layout_below="@id/editText"       android:layout_alignParentEnd="true"       android:layout_marginTop="5dp"       android:text="Search" /> </RelativeLayout>

Step 3 − Add the following code to MainActivity.kt

import android.app.SearchManager import android.content.Intent import android.os.Bundle import android.widget.Button import android.widget.EditText import androidx.appcompat.app.AppCompatActivity class MainActivity : AppCompatActivity() {    lateinit var editText: EditText    lateinit var btnSearch: Button    override fun onCreate(savedInstanceState: Bundle?) {       super.onCreate(savedInstanceState)       setContentView(R.layout.activity_main)       title = "KotlinApp"       editText = findViewById(R.id.editText)       btnSearch = findViewById(R.id.btnSearch)       btnSearch.setOnClickListener {          val intent = Intent(Intent.ACTION_WEB_SEARCH)          val term = editText.text.toString()          intent.putExtra(SearchManager.QUERY, term)          startActivity(intent)       }    } }

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="app.com.q36"> <uses-permission android:name="android.permission.INTERNET" /> <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>    </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 −
