Android OnClickListener in an ImageView of ListView

I have a ListView in my layout. To display the listing in it, I have used the following code.

ListView shopActivityListView = (ListView) findViewById(R.id.shopActivityListView);
shopActivityListView.setAdapter(new ArrayAdapter<String>(getApplicationContext(), R.layout.shopitem, R.id.text1,trackArr[1]));

Here is xml for shopitem.xml

<?xml version="1.0" encoding="utf-8"?>
<TwoLineListItem xmlns:android="http://schemas.android.com/apk/res/android" 
    android:paddingTop="2dip"
    android:paddingBottom="2dip"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:mode="twoLine"> <!-- android:background="@drawable/homebg" -->
    <TextView xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/text1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:paddingTop="6dip"
        android:paddingLeft="44dip"
        android:textStyle="bold" 
        android:lines="1"
        android:textColor="#FFFFFF"/>
    <ImageView
            android:id="@+id/buyBtn"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
             android:paddingTop="3dip"
            android:layout_marginLeft="252dip"
            android:layout_alignRight="@android:id/text1"
            android:src="@drawable/btnbuy"/>            
</TwoLineListItem>

Now I want to add a onClickListener on the ImageView of each item. How can I add it?

You have to implement ArrayAdapter and put onclicklistners in GetView. Here is a link to custom listview : http://www.softwarepassion.com/android-series-custom-listview-items-and-adapters/

GetView function is under implemented ArrayAdapter class.

Implement the OnItemClickListener and set it up for the listView. Make the ImageView clickable in the android xml.

In the method onItemClick check for the ImageView id and you should be good to go..
