Here I have created Checkbox function in android. In android CheckBox is a type of two state button either checked or unchecked. We can use checkbox to activate/deactivate the specific action. In the below code example, I have described how to make checkbox in android.

Step(1)- activity_main.xml

<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"  
    tools:context=".MainActivity" >  

    <CheckBox  
        android:id="@+id/checkBox1"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_alignParentLeft="true"  
        android:layout_alignParentTop="true"  
        android:text="Civic" />  

    <CheckBox  
        android:id="@+id/checkBox2"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_alignParentTop="true"  
        android:layout_toRightOf="@+id/checkBox1"  
        android:text="Honda"/>  

    <CheckBox  
        android:id="@+id/checkBox3"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_alignParentTop="true"  
        android:layout_toRightOf="@+id/checkBox2"  
        android:text="Amaze />  

    <Button  
        android:id="@+id/button1"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:layout_below="@+id/checkBox2"  
        android:layout_marginTop="32dp"  
        android:layout_toLeftOf="@+id/checkBox3"  
        android:text="Order" />  

</RelativeLayout>  

Step(2)- MainActivity.java class

  public class MainActivity extends Activity {  
    CheckBox Civic,Honda,Amaze;  
    Button buttonOrder;  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
        addListenerOnButtonClick();  
    }  
public void addListenerOnButtonClick(){  
    //Getting instance of CheckBoxes and Button from the activty_main.xml file  
    Civic=(CheckBox)findViewById(R.id.checkBox1);  
     Honda=(CheckBox)findViewById(R.id.checkBox2);  
    Amaze=(CheckBox)findViewById(R.id.checkBox3);  
    buttonOrder=(Button)findViewById(R.id.button1);  

    //Applying the Listener on the Button click  
    buttonOrder.setOnClickListener(new OnClickListener(){  

        @Override  
        public void onClick(View view) {  
            int totalamount=0;  
            StringBuilder result=new StringBuilder();  
            result.append("Selected Items:");  
            if(Civic.isChecked()){  
                result.append("\nCivic 100000Rs");  
                totalamount+=100;  
            }  
            if(Honda.isChecked()){  
                result.append("\nHonda 500000Rs");  
                totalamount+=50;  
            }  
            if(Amaze.isChecked()){  
                result.append("\nAmaze 120000Rs");  
                totalamount+=120;  
            }  
            result.append("\nTotal: "+totalamount+"Rs");  
            Toast.makeText(getApplicationContext(), result.toString(), Toast.LENGTH_LONG).show();  
        }  

    });  
}  
    @Override  
    public boolean onCreateOptionsMenu(Menu menu) {  
        // Inflate the menu; this adds items to the action bar if it is present.  
        getMenuInflater().inflate(R.menu.activity_main, menu);  
        return true;  
    }  

}
