Program to create custom checkbox in android/custom checkbox sample program

 In this example, I’ll show a simple example using custom checkbox

CustomCheckboxActivity.java
package com.example;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.Toast;

public class CustomCheckboxActivity extends Activity {
    private CheckBox checkBox1;
      private CheckBox checkBox2;

      /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        checkBox1=(CheckBox)findViewById(R.id.checkBox1);
        checkBox2=(CheckBox)findViewById(R.id.checkBox2);
        Button button=(Button)findViewById(R.id.button1);
        button.setOnClickListener(new OnClickListener() {
                 
                  public void onClick(View v) {
                        if(checkBox1.isChecked()==true && checkBox2.isChecked()){
                              Toast.makeText(getApplicationContext(), checkBox1.getText()+"  "+checkBox2.getText(), Toast.LENGTH_LONG).show();
                        }
                        else if (checkBox1.isChecked()==true){
                              Toast.makeText(getApplicationContext(), checkBox1.getText(), Toast.LENGTH_LONG).show();
                              }
                        else if(checkBox2.isChecked()==true){
                              Toast.makeText(getApplicationContext(), checkBox2.getText(), Toast.LENGTH_LONG).show();
                             
                        }
                       
                  }
            });
       
    }
}
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#ffffff"
    >
<TextView 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/hello"
    />
<CheckBox
android:text="  OptionOne"
android:textColor="#000000"
android:button="@drawable/custom_checkbox"
android:id="@+id/checkBox1"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</CheckBox>
<CheckBox
android:text="  OptionTwo"
android:textColor="#000000"
android:button="@drawable/custom_checkbox"
android:id="@+id/checkBox2"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</CheckBox>
<Button
android:text="Button"
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</Button>
</LinearLayout>

To customize checkbox, create an xml file in drawable folder
res/drawable/custom_checkbox.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
 <item
 android:state_checked="true"
 android:drawable="@drawable/checkbox_checked"/>
 <item
 android:state_checked="false"
 android:drawable="@drawable/checkbox_unchecked" />
</selector>

Also save two images in drawable folder to indicate the checked and unchecked state
