<ListView
    android:choiceMode="multipleChoice"
    android:id="@+id/lv"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" />

This is java code:

import java.util.ArrayList;
import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
 import android.widget.Button;
import android.widget.ListView;
import android.widget.Toast;

public class MainActivity extends Activity {
Button b;
int PICK_CONTACT;
ArrayList<String> al;
ArrayAdapter<String> aa;
ListView lv;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    b = (Button) findViewById(R.id.b);

    lv = (ListView) findViewById(R.id.lv);
    al = new ArrayList<String>();



    b.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {

            displaycontacts();
            System.out.println("size" + al.size());
            aa = new ArrayAdapter<String>(MainActivity.this,
                        android.R.layout.simple_list_item_multiple_choice, al);
            lv.setAdapter(aa);


        }
    });

    lv.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int position ,long arg3) 
        {

            //here i should get the item which is checked
        }
    });

}

public void displaycontacts() {
    try {
        ContentResolver cr = getContentResolver();
        Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
                null, null, null);

        if (cur.getCount() > 0) {
            while (cur.moveToNext()) {

                String name = cur
                        .getString(cur
                                .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                if (Integer
                        .parseInt(cur.getString(cur
                                .getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                    System.out.println("name : " + name);
                    al.add(name);

                }
            }

        }

    } catch (Exception e) {
        System.out.println("Error:::::::::::::::::::" + e);
    }

}
}

You need more information than the display name to identify a contact. So consider using CursorAdapter to get and hold on to that information.

If you are working with contacts you might want to use ContactsContract.ContactsColumns.LOOKUP_KEY to identify contacts. In that case...

use ListView.getCheckedItemPositions() to get the positions of checked items
then ListView.getItemAtPosition(int) to get the Cursor moved to that position

get the contact's lookup value

cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));

and put the array/list of lookup values in the extras of the intent used to start the activity.

Try this example, you need:

Interface
Data (String text, boolean selected)
Adapter
Fragment or Activity
list_item.xml

You can start with data:

public class MultipleData {
    private String text;
    private boolean selected;

    public MultipleData(String text, boolean selected) {
        this.text = text;
        this.selected = selected;
    }

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }

    public boolean isSelected() {
        return selected;
    }

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

list_item.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/list_item_text"
        android:layout_width="match_parent"
        android:layout_height="90dp"
        android:text="@string/app_name"
        android:layout_toLeftOf="@+id/list_item_check_button"
        android:gravity="center"/>

    <RadioButton
        android:id="@+id/list_item_check_button"
        android:layout_width="wrap_content"
        android:layout_height="90dp"
        android:layout_alignParentRight="true"
        android:checked="false"
        android:clickable="false"
        android:focusable="false" />

</RelativeLayout>

activity_mail.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">

        <ListView
            android:id="@+id/fragment_multiple_list_view"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

</RelativeLayout>

Adapter

public class MultipleAdapter extends BaseAdapter implements SelectedIndex {

    private final Context mContext;
    List<MultipleData> mList;

    @Override
    public void setSelectedIndex(int position) {

        if (mList.get(position).isSelected()) {
            mList.get(position).setSelected(false);
        } else {
            mList.get(position).setSelected(true);
        }
    }

    static class ViewHolder {
        TextView mTextView;
        RadioButton mRadioButton;
    }

    public MultipleAdapter(Context context, List<MultipleData> list) {
        this.mContext = context;
        this.mList = list;
    }

    @Override
    public int getCount() {
        return mList.size();
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View rowView = convertView;

        if (rowView == null) {
            LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            rowView = inflater.inflate(R.layout.list_item, null);

            ViewHolder viewHolder = new ViewHolder();
            viewHolder.mTextView = (TextView) rowView.findViewById(R.id.list_item_text);
            viewHolder.mRadioButton = (RadioButton) rowView.findViewById(R.id.list_item_check_button);

            rowView.setTag(viewHolder);
        }

        // fill data
        ViewHolder holder = (ViewHolder) rowView.getTag();
        holder.mTextView.setText(mList.get(position).getText());
        holder.mRadioButton.setChecked(mList.get(position).isSelected());

        return rowView;
    }

}

Interface

public interface SelectedIndex {
    void setSelectedIndex(int position);
}

In your fragment or activity:

public class MultipleFragment extends Fragment implements AdapterView.OnItemClickListener {

    MultipleAdapter mAdapter;

    public MultipleFragment() {
        // Required empty public constructor
    }

    public static MultipleFragment newInstance() {
        return new MultipleFragment();
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view = inflater.inflate(R.layout.fragment_multiple, container, false);
        ListView listView = (ListView) view.findViewById(R.id.fragment_multiple_list_view);

        MultipleData android = new MultipleData("Android", false);
        MultipleData iPhone = new MultipleData("iPhone", false);
        MultipleData windowsMobile = new MultipleData("WindowsMobile", false);

        MultipleData blackberry = new MultipleData("Blackberry", false);
        MultipleData webOS = new MultipleData("WebOS", false);
        MultipleData ubuntu = new MultipleData("Ubuntu", false);

        MultipleData windows7 = new MultipleData("Windows7", false);
        MultipleData max = new MultipleData("Max OS X", false);
        MultipleData linux = new MultipleData("Linux", false);

        MultipleData os = new MultipleData("OS/2", false);
        MultipleData symbian = new MultipleData("Symbian", false);

        List<MultipleData> list = new ArrayList<>();
        list.add(0, android);
        list.add(1, iPhone);
        list.add(2, windowsMobile);

        list.add(3, blackberry);
        list.add(4, webOS);
        list.add(5, ubuntu);

        list.add(6, windows7);
        list.add(7, max);
        list.add(8, linux);

        list.add(9, os);
        list.add(10, symbian);

        mAdapter = new MultipleAdapter(getActivity(),list);
        listView.setAdapter(mAdapter);
        listView.setOnItemClickListener(this);
        return view;
    }

    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
        mAdapter.setSelectedIndex(position);
        mAdapter.notifyDataSetChanged();
    }
}
