Hello Friends i am using a listview containing textview and radio group. Now i need to use context menu on Listview. when i was not using Radio Group it was working but now when i added Radio Buttons in my list row its not clickable. Can anyone give me solution?

This is my main layout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#FFFFFF"
    android:orientation="vertical" >

    <include layout="@layout/search_bar" />

    <ListView
        android:id="@+id/listview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_below="@+id/rel_my_search"
        android:cacheColorHint="#00000000"
        android:choiceMode="singleChoice"
        android:clickable="true"
        android:fastScrollEnabled="true" >
    </ListView>

</RelativeLayout>

and this is row of listview

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/relativelay"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/list_bg" >

    <TextView
        android:id="@+id/tvname"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:maxLines="1"
        android:padding="10dp"
        android:textColor="#000000"
        android:textSize="18dp"
        android:textStyle="bold" />

    <RadioGroup
        android:id="@+id/radioGroup1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:orientation="horizontal" >

        <RadioButton
            android:id="@+id/check_present"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:layout_marginRight="20dp"
            android:onClick="onPresentClick" />

        <RadioButton
            android:id="@+id/check_absent"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_toLeftOf="@id/check_present"
            android:onClick="onPresentClick" />
    </RadioGroup>

</RelativeLayout>

and this is the code i done

public class MainActivity extends Activity implements TextWatcher,
        OnItemClickListener/*, OnItemLongClickListener*/ {



    ListView listView;
    List<Items> items;
    List<Items> filterArray = new ArrayList<Items>();

        mySearch.addTextChangedListener(this);

        // XML Parsing Using AsyncTask...
        if (isNetworkAvailable()) {
            new MyTask().execute();
        } else {

            this.finish();
        }
    }

    public void onPresentClick(View view) {
        switch (view.getId()) {
        case R.id.check_present:

            break;
        case R.id.check_absent:

                    Toast.LENGTH_LONG).show();
            break;
        }
    }

                    }
                });
