Answer 1

This is an example about how you can call to number 123456789.

Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:123456789"));
startActivity(intent);

Just put it in OnItemClickListener() method of your listView. Hope that will help you out.

write under button onclick

    String number = "123456789";//mobile number
    Intent intent = new Intent(Intent.ACTION_CALL);
    intent.setData(Uri.parse("tel:" +number));
    startActivity(intent)

 String mono = "9876543210";//mobile number
    Intent intent = new Intent(Intent.ACTION_CALL);
    intent.setData(Uri.parse("tel:" +mono));
