Android获取Contact Number的例子

下面是论坛上有人写的关于获取Contact Number的code，非常详细，供参考。

String[] projection = new String[] {
People._ID,
People.NAME,
People.NUMBER,
};

// Get the base URI for People table in Contacts content provider.
// which is: content://contacts/people/
Uri contactUri = People.CONTENT_URI;

// Best way to retrieve a query; returns a managed query.
Cursor peopleCursor = managedQuery (contactUri,
projection, //Which columns to return.
null, // WHERE clause--we won't specify.
null, // Selection Args??
People.DEFAULT_SORT_ORDER); // Order-by name

// go to the beginning of the list
peopleCursor.moveToFirst();


// So, here we have a contact. We need to get the contact ID (_id) then
// build the Uri to get the phones section of that user's record
// which is a subdirectory of a contact record

long personId = peopleCursor.getLong(peopleCursor.getColumnIndex("_id"));

Uri personUri = ContentUris.withAppendedId(contactUri, personId );

// So now the URL looks like: content://contacts/people/_id(where the actual id of the record is here)
Uri phoneUri=
Uri.withAppendedPath(personUri, Contacts.People.Phones.CONTENT_DIRECTORY);

// Now the URL looks like: content://contacts/people/_id/phones (where phones is literally "phones")

// Now get all the phone numbers for this contact
Cursor phonesCursor = managedQuery(phoneUri,
null,
null,
null,
Phones.DEFAULT_SORT_ORDER);

// We now have a cursor for all the phone numbers for that User ID
// go to the beginning of the phone list.
phonesCursor.moveToFirst();
