如何获取联系人的电话号码？
问题描述：
代码如下：
String[] columns = {ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.Contacts.HAS_PHONE_NUMBER};
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, columns, null, null, null);
int ColumeIndex_ID = cursor.getColumnIndex(ContactsContract.Contacts._ID);
int ColumeIndex_DISPLAY_NAME = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
int ColumeIndex_HAS_PHONE_NUMBER = cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER);
while(cursor.moveToNext())
{
String id = cursor.getString(ColumeIndex_ID);
String name = cursor.getString(ColumeIndex_DISPLAY_NAME);
String has_phone = cursor.getString(ColumeIndex_HAS_PHONE_NUMBER);
if(!has_phone.endsWith("0"))
{
System.out.println(name);
GetPhoneNumber(id);
}
}
cursor.close();
public String GetPhoneNumber(String id)
{
String number = "";
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone._ID + " = " + id, null, null);
if(phones.getCount() > 0)
{
while(phones.moveToNext())
{
number = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
System.out.println(number);
}
phones.close();
return number;
}
我能获取联系人的姓名，但是不能在GetPhoneNumber()中获取电话号码。
phones.getCount() 总是等于0，如何修改?

Android Contact API 2.0
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
"DISPLAY_NAME = '" + NAME + "'", null, null);
if (cursor.moveToFirst()) {
String contactId =
cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
//
// Get all phone numbers.
//
Cursor phones = cr.query(Phone.CONTENT_URI, null,
Phone.CONTACT_ID + " = " + contactId, null, null);
while (phones.moveToNext()) {
String number = phones.getString(phones.getColumnIndex(Phone.NUMBER));
int type = phones.getInt(phones.getColumnIndex(Phone.TYPE));
switch (type) {
case Phone.TYPE_HOME:
// do something with the Home number here...
break;
case Phone.TYPE_MOBILE:
// do something with the Mobile number here...
break;
case Phone.TYPE_WORK:
// do something with the Work number here...
break;
}
}
phones.close();
}
cursor.close();

试一下方法：
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Log.i("Names", name);
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
{
// Query phone here. Covered next
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id,null, null);
while (phones.moveToNext()) {
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Log.i("Number", phoneNumber);
}
phones.close();
}
}
}
