我尝试了多种组合，但在找到电话号码时显示错误 这是我的代码：
public void readPhoneLookUp(){
Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
//people.moveToFirst();
while(people.moveToNext()) {
int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME);
String contact = people.getString(nameFieldColumnIndex);
Log.i(LOG, "Contacts: "+ contact);
int numberFieldColumnIndex = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
String number = people.getString(numberFieldColumnIndex);
Log.i(LOG, "Number: "+ number);
}
}//readPhoneLookUp ends
我还在Manifest中添加了 READCONTACTS权限 我也试过这个：
public void readContactsNew(){
ArrayList<String> contactListArrLst = null;
contactListArrLst = new ArrayList<String>();
ArrayList<String> contactNumberArrLst = null;
contactNumberArrLst = new ArrayList<String>();
ContentResolver contentResolver = getContentResolver();
Cursor cursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
int curCount = cursor.getCount();
Log.i(LOG, "Contacts:Count "+ curCount);
cursor.moveToFirst();
while(!cursor.isAfterLast()){
contactListArrLst.add(cursor.getString(cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME)));
contactNumberArrLst.add(cursor.getString(cursor.getColumnIndex(PhoneLookup.NUMBER)));
cursor.moveToNext();
}
cursor.close();
Log.i(LOG, "Contacts: "+ contactListArrLst);
Log.i(LOG, "ContactNumber: "+ contactNumberArrLst);
但是在contactNumberArrLst中给出了错误
这是Log Cat中的错误：

试试此代码
Cursor c = activity.getContentResolver().query(Data.CONTENT_URI,
new String[] {Data._ID, Data.DISPLAY_NAME,Phone.NUMBER,
Data.CONTACT_ID,
Phone.TYPE,
Phone.LABEL},
Data.MIMETYPE + "='" + Phone.CONTENT_ITEM_TYPE + "'",
null,
Data.DISPLAY_NAME);
int count = c.getCount();
boolean b = c.moveToFirst();
String[] columnNames = c.getColumnNames();
int displayNameColIndex = c.getColumnIndex("display_name");
int idColIndex = c.getColumnIndex("_id");
int col2Index = c.getColumnIndex(columnNames[2]);
int col3Index = c.getColumnIndex(columnNames[3]);
List<ContactItem> contactItemList = new LinkedList<ContactItem>();
for(int i = 0; i < count ; i ++) {
String displayName = c.getString(displayNameColIndex);
String phoneNumber = c.getString(col2Index);
int contactId = c.getInt(col3Index);
}

阅读用户的主要电话号码（用户ID为变量＆＃39; id＆＃39;）
Cursor cursor = mResolver.query(ContactsContract.Contacts.CONTENT_URI,
new String[]{ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.HAS_PHONE_NUMBER,
ContactsContract.Contacts.PHOTO_ID
}, ContactsContract.Contacts._ID + "=?"
, new String[]{String.valueOf(id)}, null);
...
if(cursor.moveToFirst()){
if(cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)) == 1){
Cursor c = mResolver.query(ContactsContract.Data.CONTENT_URI
, new String[]{ Phone.NUMBER
}
, Phone.CONTACT_ID + "=? AND " + Data.MIMETYPE + "=? AND " + Data.IS_PRIMARY + "=1"
, new String[]{ String.valueOf(id),Phone.CONTENT_ITEM_TYPE }, null);
if(c.moveToFirst()){
// use phone number : sSecondLine.setText( c.getString(c.getColumnIndex(Phone.NUMBER)) );
}
c.close();
}
cursor.close();
最重要的导入行：
import android.provider.ContactsContract;
import android.provider.ContactsContract.CommonDataKinds.Phone;
import android.provider.ContactsContract.Contacts;
import android.provider.ContactsContract.Contacts.Data;
以下是阅读所有电话号码的摘录：
Cursor c = getContentResolver().query(ContactsContract.Data.CONTENT_URI
, new String[]{ Phone.NUMBER, Phone.TYPE
}
, Phone.CONTACT_ID + "=? AND " + Data.MIMETYPE + "=?"
, new String[]{ sValuesMap.get(name),Phone.CONTENT_ITEM_TYPE }, Data.IS_PRIMARY + " desc");
第一条记录将是主要电话号码。

根据contact_id来自联系人的电话号码
//Get phone number
Cursor cursorPhone = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ? AND " +
ContactsContract.CommonDataKinds.Phone.TYPE + " = " +
ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE,
new String[]{id.toString()},
null);
String contactNumber = null;
if (cursorPhone.moveToFirst()) {
contactNumber = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
contactNumber = contactNumber.replaceAll("[\\D]", "");
System.out.println("contactnum" + contactNumber);
if (contactNumber.length() >= 10) {
System.out.println("contactnum1" + contactNumber);
contactNumber = contactNumber.substring(contactNumber.length() - 10);
System.out.println("contactnum2" + contactNumber);
}
edittext.setText(contactNumber);
}
