In Android how to create app for playing corresponding videos for each item selected from the drop down list. For example. Our application has two activity screen.

In Mainactivity (screen1) having list of item like item1, item2,item3, item4 etc also res folder contains different videos.

1. when i select item1 on Mainactivity dropdown list , on second activity(screen2) play corresponding video for item1

2. Same as above if select item2 corresponding video would be play on second activity(screen2)

Please guide me to code in Android(java)
