Example Of Android TextView Using Kotlin

In this section, you will see how to use android TextView using kotlin. Follow the steps below to create new android project. After that, we will use Textview in it. Please ignore the steps if you have already created a new android project.

1. Creating New Project in Kotlin

Step Description
1. Open Android Studio.
2. Go to File => New => New Project. Write application name as TextView. Then, check Include Kotlin Support and click next button.
3. Select minimum SDK you need. However, we have selected 17 as minimum SDK. Then, click next button
4. Then, select Empty Activity => click next => click finish.
5. If you have followed above process correctly, you will get a newly created project successfully.

You can also have a look at our tutorial on Create Android Project in Android. Steps in this tutorial are similar as discussed above.

Now, we are going to changes the code into xml and kotlin file. So, follow the steps below.

2. Modify Values Folder

Open res/values/strings.xml file and add below code into it.

	<string name="app_name">TextViewUsingKotlin</string>
	<string name="click_on_me">Click On Me</string>
	<string name="clicked_on_me">You clicked on me.</string>

Since other values folders have not been changed. So, we are not going to mention it here.

3. Use TextView in xml File

Open res/layout/activity_main.xml file. Add below code into it. You may also visit post to create and use Textview programmatically in kotlin

<?xml version="1.0" encoding="utf-8"?>


Note that we have add TextView widget in this xml file.

Now, we will access this TextView in kotlin file and perform some action.

4. Access TextView in Kotlin File

Since we are done with xml and values folder changes. Now, we will see how to access TextView using kotlin and perform some action on click of it. So, open src/main/java/com.tutorialwing.textview/MainActivity.kt file. Then, add below code into it.

package com.tutorialwing.textview

import android.os.Bundle
import android.widget.TextView
import android.widget.Toast

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {

        val textView = findViewById( as TextView
        textView?.setOnClickListener { Toast.makeText(this@MainActivity, R.string.clicked_on_me, Toast.LENGTH_LONG).show() }

In this kotlin file, we are showing a Toast message on click of TextView widget. However, you can perform any action you need.

AndroidManifest.xml file

Since AndroidManifest is very important file in any android application. We are also going to see the code inside main/AndroidManifest.xml file.

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.tutorialwing.textview"

		<activity android:name=".MainActivity">
				<action android:name="android.intent.action.MAIN"/>

				<category android:name="android.intent.category.LAUNCHER"/>

Finally, when you run the app, you will get output as shown above.
That’s end of our tutorial on TextView using Kotlin Programming language.
