Android snippet of the day - Show Contact Picker
This quickie will get you up and running if you need to display the android built in contact picker to select a phone number with a minimum amount of code.
What's the problem?
Well, after looking for a quick way to select a phone number from within the built in Contact Picker in Android, I stumbled upon a remarkable number of articles with faulty information.
This is what finally worked!
private void selectContact()
{
// This intent will fire up the contact picker dialog
Intent intent = new Intent(Intent.ACTION_PICK,
ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
startActivityForResult(intent, REQUEST_CONTACTPICKER);
}
If all you wanted to do was to show the contact picker, this would be enough! However I suspect you wish to be notified of which phone number was selected.
Retrieving the result
To actually be notified of the selected result, we need to override the onActivityResult method. This assumes you're implementing the functionality inside an Activity. This is where it can get a bit messy! I'll just post the method and won't bother going into detail as you're probably not interested. If you are, there are plenty of info if you google around a bit.
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CONTACTPICKER)
{
if(resultCode == RESULT_OK)
{
Uri contentUri = data.getData();
String contactId = contentUri.getLastPathSegment();
Cursor cursor = getContentResolver().query(
Phone.CONTENT_URI, null,
Phone._ID + "=?", // < - Note, not CONTACT_ID!
new String[]{contactId}, null);
startManagingCursor(cursor);
Boolean numbersExist = cursor.moveToFirst();
int phoneNumberColumnIndex = cursor.getColumnIndex(Phone.NUMBER);
String phoneNumber = "";
while (numbersExist)
{
phoneNumber = cursor.getString(phoneNumberColumnIndex);
phoneNumber = phoneNumber.trim();
numbersExist = cursor.moveToNext();
}
stopManagingCursor(cursor);
if (!phoneNumber.equals(""))
{
setPhoneNumber(phoneNumber);
} // phoneNumber != ""
} // Result Code = RESULT_OK
} // Request Code = REQUEST_CONTACTPICER
} // end function
Basically what this does is open up the contact phone database at the record with the id of the selected number!
In many cases when browsing for a working solution for this, the problem was this statement at line 11: Phone._ID + "=?", the examples I found had specified it as Phone.CONTACT_ID + "=?" which is used to find a specific contact, not a number.
Oh right, the compilation errors
Unless you've already figured it out, you need a few things for this to work.
1. REQUEST_CONTACTPICKER needs to be specified, something like this:
2. You need these imports:
That's it.
