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"?>
<android.support.constraint.ConstraintLayout xmlns:android = "http://schemas.android.com/apk/res/android"
   xmlns:app = "http://schemas.android.com/apk/res-auto"
   xmlns:tools = "http://schemas.android.com/tools"
   android:layout_width = "match_parent"
   android:layout_height = "match_parent"
   tools:context = ".MainActivity">
   <CheckedTextView
      android:id = "@+id/text"
      android:layout_width = "wrap_content"
      android:layout_height = "wrap_content"
      android:text = "Checked Text View"
      android:textSize = "25sp"
      app:layout_constraintBottom_toBottomOf = "parent"
      app:layout_constraintLeft_toLeftOf = "parent"
      app:layout_constraintRight_toRightOf = "parent"
      app:layout_constraintTop_toTopOf = "parent" />

public class MainActivity extends AppCompatActivity {
   CheckedTextView text;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      text = findViewById(R.id.text);
      text.setCheckMarkDrawable(null);
      text.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
