问题
I'm having a problem with extracting phone numbers of some people in my contact list.
First I show all the contacts in a listview:
String[] projection = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER
};
mCursor = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
projection, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=?", new String[] {mContactId}, null);
When clicking on an item, this is how I fetch the contact_id:
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
Cursor currentCursor = mContactsAdapter.getCursor();
if (currentCursor != null) {
notifyOnContactSelectedListeners(String.valueOf(id));
}
}
Then I create a new fragment, and while loading it I query for the contact's phone & display name:
if (cursor != null && cursor.getCount() > 0) {
cursor.moveToFirst();
String firstName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String number = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
So for some people that has a phone, I get the phone number this way and that's ok. But for some people I can't get the phone number this way - but they do have phone number in the default's phone contacts book.
What went wrong?
回答1:
I had a similar difficulty. I discovered that the numbers that I was unable to receive had all been imported from my linked Facebook account. You will be able to detect that the contact exists, and indeed that they have a phone number. However, when you try to retrieve said number with a SQL query the result returned will be null
.
It transpired that Facebook restrict access to their contacts for security reasons. I am yet to find another provider (e.g. LinkedIn, Google) which hides phone numbers.

try this may it useful for you
public class Contact extends Activity implements OnItemClickListener{
private static final int PICK_CONTACT = 0;
Cursor c;
Cursor cursor,phones,emails,address;
String id,phoneNo,name;
String[] from;
int[] to;
ListView lv;
Cursor cur,pCur;
List<String> list1 = new ArrayList<String>();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.contact);
lv = (ListView)findViewById(R.id.contactlist);
displayContacts();
lv.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, list1));
lv.setOnItemClickListener(this);
}
private void displayContacts() {
ContentResolver cr = getContentResolver();
cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer.parseInt(cur.getString(
cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
phoneNo = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
// setContact(name,phoneNo);
System.out.println("name"+name+"ph no"+phoneNo);
list1.add(name+"\n"+phoneNo);
// Toast.makeText(this, "Name: " + name + ", Phone No: " + phoneNo, Toast.LENGTH_SHORT).show();
}
pCur.close();
}
}
}
}
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
String s = lv.getItemAtPosition(arg2).toString();
Log.i("my msg", s.substring(0, s.indexOf("\n")));
Toast.makeText(this, s.substring(s.indexOf("\n")+1,s.length() ),1 ).show();
}
}

I received null
in some contacts.
I verified my code to find out that when querying phone numbers I was using ContactsContract.CommonDataKinds.Phone.NORMALIZED_NUMBER
then I changed to ContactsContract.CommonDataKinds.Phone.NORMALIZED_NUMBER
that according to android docs it says it is
The phone number as the user entered it.
and the code worked well.
