<string>[{"UserId":"1","Usercode":"ADMIN","Password":"123"},
{"UserId":"2","Usercode":"Ravi","Password":"ravi"}]</string>

Android studio. The program includes the ListView component. The ListView Item is populated via adapter from strings.xml. Each Item contains several words and one of them is a phone number. There is no problem filling in the Item. Need to do this when click (onclick) on a separate Item, program need to dial the number (call) that is specified inside the Item. How this can be done. Thanks.
