Getting Started

At first, we will create android project. Then, we will create and use checkedTextview programmatically in kotlin file in this application.

1. Creating New Project in Kotlin

Follow the steps below to create new project. Please ignore the steps if you have already created a new project.

Step Description
1. Open Android Studio.
2. Go to File => New => New Project. Write application name as DynamicCheckedTextView. 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. At this point, You will get a newly created android project successfully.

Now, we will modify xml and kotlin file to use checkedTextview dynamically.

2. Modify Values Folder

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

	<string name="app_name">DynamicCheckedTextView</string>
	<string name="checkedTextView">CheckedTextView</string>
	<string name="checked">checked</string>
	<string name="unchecked">unchecked</string>
	<string name="pre_msg">CheckedTextView is</string>

No other values folders have been modified. So, we are not going to mention them here.

3. Modify Layout Folder

Open res/layout/activity_main.xml file. Then, add below code into it.

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


In activity_main.xml file, we have defined a linearLayout, with id rootContainer, that will act as container for the checkedTextview created programmatically in the application.

4. Create Android CheckedTextView Programmatically / Dynamically in Kotlin

Open app/src/main/java/com.tutorialwing.dynamiccheckedtextview/MainActivity.kt file. Then, add below code into it.

package com.tutorialwing.dynamiccheckedtextview

import android.os.Bundle
import android.view.ViewGroup
import android.widget.CheckedTextView
import android.widget.LinearLayout
import android.widget.Toast

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {

        val linearLayout = findViewById<LinearLayout>(

        val checkedTextView = CheckedTextView(this)
        checkedTextView.layoutParams = LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)
        checkedTextView.isChecked = false

        checkedTextView.setOnClickListener {
            checkedTextView.isChecked = !checkedTextView.isChecked
            checkedTextView.setCheckMarkDrawable(if (checkedTextView.isChecked) android.R.drawable.checkbox_on_background else android.R.drawable.checkbox_off_background)

            val msg = getString(R.string.pre_msg) + " " + if (checkedTextView.isChecked) getString(R.string.checked) else getString(R.string.unchecked)
            Toast.makeText(this@MainActivity, msg, Toast.LENGTH_SHORT).show()

        // Add Checkbox to LinearLayout

In MainActivity.kt file, we have create checkedTextview programmatically in kotlin file. Then, we set some width, height, text etc.. Notice how we use different methods to set text, width or height. Similarly, you can use such methods to customise this widget. After that, we set click listener to show toast message whenever checkedTextview widget is clicked.

Since AndroidManifest.xml file is very important in any android application, we are also going to see the content inside this file.

AndroidManifest.xml file

Code inside src/main/AndroidManifest.xml file is –

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

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

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


When we run the program, we will get output as shown above.

That’s end of our tutorial on Creating Android CheckedTextview Programmatically in Kotlin.
