<LinearLayout 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"
      tools:context=".CheckedTextViewExample"
      android:padding="16dp"
      android:orientation="vertical"
      android:gravity="center">
   
      <CheckedTextView
          android:id="@+id/checkedtextview1"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:text="Checked TextView"
          android:textColor="@color/design_default_color_primary"
          android:textSize="20sp"
          android:checkMark="?android:attr/listChoiceIndicatorMultiple"
          />
   
</LinearLayout>

                                    
                                      package com.example.widgets;
    
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.CheckedTextView;
import android.widget.Toast;
    
public class CheckedTextViewExample extends AppCompatActivity {
   
      CheckedTextView checkedTextView;
   
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_checked_text_view_example);
   
          checkedTextView=(CheckedTextView) findViewById(R.id.checkedtextview1);
   
          checkedTextView.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View v) {
                  checkedTextView.toggle();
                  if (checkedTextView.isChecked()){
                      Toast.makeText(getApplicationContext(),"Checked by you",Toast.LENGTH_LONG).show();
                  }else{
                      Toast.makeText(getApplicationContext(),"Unchecked by you",Toast.LENGTH_LONG).show();
                  }
              }
          });
   
      }
}

                                    
                                      package com.example.widgets

        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_checked_text_view_example)

        checkedTextView = findViewById(R.id.checkedtextview1)

        checkedTextView.setOnClickListener {
            checkedTextView.toggle()
            val message = if (checkedTextView.isChecked) "Checked by you" else "Unchecked by you"
