Another Two classes for ListView Control.

    holder.text.setText(list.get(position).getName());

    holder.checkbox.setChecked(list.get(position).isSelected());


    return view;
    }
} 

And

package com.example.new_group_and_add_contacts;

public class Model {

private String name;
private boolean selected;

public Model(String name) {
    this.name = name;
    selected = false;
}

public String getName() {

}

public void setName(String name) {
    this.name = name;
}

public boolean isSelected() {
    return selected;
}

public void setSelected(boolean selected) {
    this.selected = selected;
}

} 

And XML Files are, This xml file name is main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" 
android:id="@+id/layoutexample"
android:background="#000000"
>

<EditText
    android:id="@+id/textview"
    android:layout_width="200dp"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:hint="Enter Group Name"
    android:textColor="#000000"
    android:layout_marginLeft="10dp"
    android:layout_marginRight="10dp"
    android:layout_marginTop="10dp"
    />


<ListView
    android:id="@+id/mylist"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:layout_weight="1"
    android:background="#552244"
    android:cacheColorHint="#00000000"
    android:layout_margin="10dp"
    >
</ListView>

<Button 
     android:id="@+id/mybutton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:text="Create New Group"
    android:onClick="onClick"
    android:layout_gravity="center_horizontal"
    android:textColor="#000000"
    />



</LinearLayout>

Another XML file for ListView, Name is rowbuttonlayout.xml.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" 
android:orientation="horizontal"
>

<CheckBox
    android:id="@+id/check"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
</CheckBox>



<TextView
    android:id="@+id/label"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello"
    android:textSize="15dp"
    android:textColor="#FF0000"         
    >
</TextView>

</LinearLayout> 

This Code is working in Andoid2.2 onwards mobiles.

Groups are not part of the contacts app / content provider / Google contacts sync adapter on Android, but you will need to use the Google Contacts API directly, see http://code.google.com/apis/contacts/docs/3.0/developers_guide_protocol.html#CreatingGroups

try this code

private void getGroupId(String groupname, String acc_name) {
        ArrayList<ContentProviderOperation> opsGroup = new ArrayList<ContentProviderOperation>();
        opsGroup.add(ContentProviderOperation.newInsert(ContactsContract.Groups.CONTENT_URI)
                .withValue(ContactsContract.Groups.TITLE, groupname)
                .withValue(ContactsContract.Groups.GROUP_VISIBLE, true)
                .withValue(ContactsContract.Groups.ACCOUNT_NAME, acc_name)
                .withValue(ContactsContract.Groups.ACCOUNT_TYPE, SharedPrefs.getString(this,"AccountType"))
                .build());
        try {
            getContentResolver().applyBatch(ContactsContract.AUTHORITY, opsGroup);
            Toast.makeText(ProspectsActivity.this, "successfully, Group is created", Toast.LENGTH_SHORT).show();
            Log.e("TAG", "successfully, Group is created");
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
