Handling Android ListView onItemClick Event

Android ListView control is designed to display a list of items to the user and the most common action users perform with the ListView is the item selection by just tapping any particular item in the ListView. ListView allows developers to handle user tapping by attaching the OnItemClickListener and overriding the onItemClick event. In most cases, when user click any item in the ListView, a new android activity opens that shows the details related to the selected item. To implement such scenario the knowledge of Android Intents and activity to activity communication is required. I will show you that in my future tutorials. In this tutorial, I will demonstrate you how you can handle the click events in ListView.
