【中文标题】android获取所有联系人【英文标题】：android get all contacts 【发布时间】：2012-09-15 17:49:38 【问题描述】：如何在我的 android 中获取所有联系人的姓名并将它们放入字符串数组中？
【问题讨论】：
你试过使用developer.android.com/reference/android/provider/…吗？ check this How to get phone contacts in Android 的可能副本 在Github Repository 上添加了一个小库来获取联系人 【参考方案1】：也试试这个，
private void getContactList()
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
if ((cur != null ? cur.getCount() : 0) > 0)
while (cur != null && cur.moveToNext())
String id = cur.getString(
cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(
ContactsContract.Contacts.DISPLAY_NAME));
if (cur.getInt(cur.getColumnIndex(
ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0)
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[]id, null);
while (pCur.moveToNext())
String phoneNo = pCur.getString(pCur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER));
Log.i(TAG, "Name: " + name);
Log.i(TAG, "Phone Number: " + phoneNo);
pCur.close();
if(cur!=null)
cur.close();

【讨论】：
由于某种原因，此代码将每个联系人获取两次。你知道为什么吗？ @Aerrow 有时会得到一些联系人两次。你解决了这个问题吗？ 不要忘记关闭光标！ 请勿使用此代码。它查询所有联系人，然后对每个联系人执行附加查询。糟糕的性能 - 在真实设备上运行可能需要 10 多秒。 @Vasiliy 是对的，如果您的联系人较少，您可能会被欺骗它很快，但对于拥有大量联系人的实际用户来说是个问题。【参考方案2】：获取联系人信息、照片联系人、照片 uri 并转换为 Class 模型
1)。类模型示例：
public class ContactModel
public String id;
public String name;
public String mobileNumber;
public Bitmap photo;
public Uri photoURI;
2)。获取联系人并转换为模型
public List<ContactModel> getContacts(Context ctx)
List<ContactModel> list = new ArrayList<>();
ContentResolver contentResolver = ctx.getContentResolver();
Cursor cursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cursor.getCount() > 0)
while (cursor.moveToNext())
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
if (cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0)
Cursor cursorInfo = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]id, null);
InputStream inputStream = ContactsContract.Contacts.openContactPhotoInputStream(ctx.getContentResolver(),
ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, new Long(id)));
Uri person = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, new Long(id));
Uri pURI = Uri.withAppendedPath(person, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
Bitmap photo = null;
if (inputStream != null)
photo = BitmapFactory.decodeStream(inputStream);
while (cursorInfo.moveToNext())
ContactModel info = new ContactModel();
info.id = id;
info.name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
info.mobileNumber = cursorInfo.getString(cursorInfo.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
info.photo = photo;
info.photoURI= pURI;
list.add(info);
cursorInfo.close();
cursor.close();
return list;
【讨论】：
很棒的功能，只需要在完成第一个while子句后再添加一行来关闭光标。非常感谢 存储所有位图可能是个坏主意，例如您加载 1000 个位图，而用户只能看到前 10 个。【参考方案3】：public class MyActivity extends Activity
implements LoaderManager.LoaderCallbacks<Cursor>
private static final int CONTACTS_LOADER_ID = 1;
@Override
public void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Prepare the loader. Either re-connect with an existing one,
// or start a new one.
getLoaderManager().initLoader(CONTACTS_LOADER_ID,
null,
this);
@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args)
// This is called when a new Loader needs to be created.
if (id == CONTACTS_LOADER_ID)
return contactsLoader();
return null;
@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor)
//The framework will take care of closing the
// old cursor once we return.
List<String> contacts = contactsFromCursor(cursor);
@Override
public void onLoaderReset(Loader<Cursor> loader)
// This is called when the last Cursor provided to onLoadFinished()
// above is about to be closed. We need to make sure we are no
// longer using it.
private Loader<Cursor> contactsLoader()
Uri contactsUri = ContactsContract.Contacts.CONTENT_URI; // The content URI of the phone contacts
String[] projection = // The columns to return for each row
ContactsContract.Contacts.DISPLAY_NAME
;
String selection = null; //Selection criteria
String[] selectionArgs = ; //Selection criteria
String sortOrder = null; //The sort order for the returned rows
return new CursorLoader(
getApplicationContext(),
contactsUri,
projection,
selection,
selectionArgs,
sortOrder);
private List<String> contactsFromCursor(Cursor cursor)
List<String> contacts = new ArrayList<String>();
if (cursor.getCount() > 0)
cursor.moveToFirst();
do
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
contacts.add(name);
while (cursor.moveToNext());
return contacts;
别忘了
<uses-permission android:name="android.permission.READ_CONTACTS" />
【讨论】：
很好地使用 CursorLoader。你知道如何从 CursorLoader 中的每个联系人中提取电话号码吗？ 您可以实现 LoaderManager.LoaderCallbacks在不到一秒钟的时间内获取所有联系人，并且不会对您的活动造成任何负担。 跟随我的步骤就像魅力一样。
ArrayList<Contact> contactList = new ArrayList<>();
private static final String[] PROJECTION = new String[]
ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER
;
private void getContactList()
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, PROJECTION, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
if (cursor != null)
HashSet<String> mobileNoSet = new HashSet<String>();
try
final int nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
final int numberIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
String name, number;
while (cursor.moveToNext())
name = cursor.getString(nameIndex);
number = cursor.getString(numberIndex);
number = number.replace(" ", "");
if (!mobileNoSet.contains(number))
contactList.add(new Contact(name, number));
mobileNoSet.add(number);
Log.d("hvy", "onCreaterrView Phone Number: name = " + name
+ " No = " + number);
finally
cursor.close();
联系人
public class Contact
public String name;
public String phoneNumber;
public Contact()
public Contact(String name, String phoneNumber )
this.name = name;
this.phoneNumber = phoneNumber;
public String getName()
return name;
public void setName(String name)
this.name = name;
public String getPhoneNumber()
return phoneNumber;
public void setPhoneNumber(String phoneNumber)
this.phoneNumber = phoneNumber;
好处
不到一秒 无负载 升序 没有重复的联系人【讨论】：
这应该是被接受的答案。因为它太快了。谢谢 这非常好。需要提到的一个关键点是，这里的最大区别在于，此优化解决方案使用的 uri 是ContactsContract.CommonDataKinds.Phone.CONTENT_URI，这使您可以直接访问 ContactsContract.CommonDataKinds.Phone.NUMBER 列。在更糟糕的答案中，您查询 uri ContactsContract.Contacts.CONTENT_URI，它不会让您访问 ContactsContract.CommonDataKinds.Phone.NUMBER 列，因此您必须使用每个联系人的 id 运行另一个查询才能访问它。【参考方案5】：
改进@Adiii 的答案 - 它将清理电话号码并删除所有重复项
声明一个全局变量
// Hash Maps
Map<String, String> namePhoneMap = new HashMap<String, String>();
然后使用下面的函数
private void getPhoneNumbers()
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
// Loop Through All The Numbers
while (phones.moveToNext())
String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
// Cleanup the phone number
phoneNumber = phoneNumber.replaceAll("[()\\s-]+", "");
// Enter Into Hash Map
namePhoneMap.put(phoneNumber, name);
// Get The Contents of Hash Map in Log
for (Map.Entry<String, String> entry : namePhoneMap.entrySet())
String key = entry.getKey();
Log.d(TAG, "Phone :" + key);
String value = entry.getValue();
Log.d(TAG, "Name :" + value);
phones.close();
请记住，在上面的示例中，键是电话号码，值是名称，因此请阅读您的内容，例如 998xxxxx282->Mahatma Gandhi 而不是 Mahatma Gandhi->998xxxxx282
【讨论】：
【参考方案6】：Cursor contacts = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
String aNameFromContacts[] = new String[contacts.getCount()];
String aNumberFromContacts[] = new String[contacts.getCount()];
int i = 0;
int nameFieldColumnIndex = contacts.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
int numberFieldColumnIndex = contacts.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
while(contacts.moveToNext())
String contactName = contacts.getString(nameFieldColumnIndex);
aNameFromContacts[i] = contactName ;
String number = contacts.getString(numberFieldColumnIndex);
aNumberFromContacts[i] = number ;
i++;
contacts.close();
结果将是一个包含联系人的NameFromContacts 数组。还要确保你已经添加了
<uses-permission android:name="android.permission.READ_CONTACTS" />
在 main.xml 中
【讨论】：
非常感谢，我会试试的，如果我有其他问题，我会问你 感谢帮助，如何在 ListView 中显示所有姓名？（我可以在另一个窗口中看到我手机中的所有联系人姓名）？谢谢 这个答案是错误的。PhoneLookup.NUMBER 不是 ContactsContract.Contacts.CONTENT_URI 中的列，numberFieldColumnIndex 总是返回 -1。
应该是这样的：Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null); while (phones.moveToNext()) String name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); phones.close();
@gunner_dev 如果你确定这个答案包括你的编辑会起作用，请写一个新的答案。【参考方案7】：
