I've got the following code to retrieve a contact list with Name + PhoneNumber:
@SuppressLint("Range")
fun getNamePhoneDetails(): ArrayList<List<String>>? {
val names = ArrayList<List<String>>()
val cr = contentResolver
val cur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
null, null, null)
if (cur!!.count > 0) {
while (cur.moveToNext()) {
val id = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NAME_RAW_CONTACT_ID))
val name = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME))
val number = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))
names.add(listOf(id, name, number))
}
}
return names
}
The output is correct once no contact has two phone numbers. However once any contact has two phone numbers I get the contact twice. It has the same id and name, but a different phone number. How can I make it so that the returned list does not have a contact twice but all phone numbers inside a list?
Something like
[1, Name Name, [phonenumber1, phonenumber2]],[2, Name Name, [phonenumber1]]
Then I could just iterate through the phonenumberlist and have all numbers as valid strings.
You should rather create a POJO Object and than assign the data into it and return a list of that POJO Object and then you can make use of distinct extension on the list to get a filtered result they way you want it . This is how you can achieve what you want :
Create a POJO Object :
data class Contact(
val id : String ,
val name : String,
val number : String)
And then when retrieveing the data you can do the following :
@SuppressLint("Range")
fun getNamePhoneDetails(): MutableList<Contact>? {
val names = MutableList<Contact>()
val cr = contentResolver
val cur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
null, null, null)
if (cur!!.count > 0) {
while (cur.moveToNext()) {
val id = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NAME_RAW_CONTACT_ID))
val name = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME))
val number = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))
names.add(Contact(id , name , number))
}
}
return names
}
And then while retreiving the data you need to just filter the list in the following manner :
val list = getNamePhoneDetails()
list.distinctBy { it.number }.forEach { println(it) }
