引言

本文档将帮助您在 Android 设备联系人中插入、搜索和删除条目。

使用代码

使用本文提供的联系人操作类，您可以轻松地对联系人列表执行插入、搜索和删除等操作。 在演示项目中，主活动展示了如何使用带有参数的联系人操作类。

代码片段展示了插入、搜索和删除函数。

向联系人插入条目

public static void Insert2Contacts(Context ctx, String nameSurname,
               String telephone) {
   if (!isTheNumberExistsinContacts(ctx, telephone)) {
       ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
       int rawContactInsertIndex = ops.size();
 
       ops.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI)
                      .withValue(RawContacts.ACCOUNT_TYPE, null)
                      .withValue(RawContacts.ACCOUNT_NAME, null).build());
       ops.add(ContentProviderOperation
                      .newInsert(ContactsContract.Data.CONTENT_URI)
                      .withValueBackReference(
                                     ContactsContract.Data.RAW_CONTACT_ID,
                                     rawContactInsertIndex)
                      .withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE)
                      .withValue(Phone.NUMBER, telephone).build());
       ops.add(ContentProviderOperation
                      .newInsert(Data.CONTENT_URI)
                      .withValueBackReference(Data.RAW_CONTACT_ID,
                                     rawContactInsertIndex)
                      .withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE)
                      .withValue(StructuredName.DISPLAY_NAME, nameSurname)
                      .build());
       try {
               ContentProviderResult[] res = ctx.getContentResolver()
                              .applyBatch(ContactsContract.AUTHORITY, ops);
       } catch (Exception e) {
 
               Log.d(TAG, e.getMessage());
       }
   }
}

在联系人中搜索条目

public static boolean isTheNumberExistsinContacts(Context ctx,
                       String phoneNumber) {
   Cursor cur = null;
   ContentResolver cr = null;
 
   try {
    cr = ctx.getContentResolver();
 
   } catch (Exception ex) {
    Log.d(TAG, ex.getMessage());
   }
 
   try {
     cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null,
                  null, null);
   } catch (Exception ex) {
     Log.i(TAG, ex.getMessage());
   }
 
   try {
       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 = ctx
                                 .getContentResolver()
                                 .query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                                                null,
                                                 ContactsContract.CommonDataKinds.Phone.CONTACT_ID
                                                                + " = " + id, null, null);
                  while (phones.moveToNext()) {
                     String phoneNumberX = phones
                             .getString(phones
                                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                     // Log.i("Number", phoneNumber);
 
                     phoneNumberX = phoneNumberX.replace(" ", "");
                     phoneNumberX = phoneNumberX.replace("(", "");
                     phoneNumberX = phoneNumberX.replace(")", "");
                     if (phoneNumberX.contains(phoneNumber)) {
                             phones.close();
                             return true;
 
                     }
 
                  }
                  phones.close();
              }
 
           }
       }
   } catch (Exception ex) {
        Log.i(TAG, ex.getMessage());
 
   }
 
   return false;
}

从联系人中删除条目

public static boolean deleteContact(Context ctx,String phoneNumber) {
Uri contactUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,
                               Uri.encode(phoneNumber));
           Cursor cur = ctx.getContentResolver().query(contactUri, null, null,
                           null, null);
           try {
               if (cur.moveToFirst()) {
                   do {
                      String lookupKey = 
                        cur.getString(cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
                      Uri uri = Uri.withAppendedPath(
                                     ContactsContract.Contacts.CONTENT_LOOKUP_URI,
                                     lookupKey);
                      ctx.getContentResolver().delete(uri, null, null);
                   } while (cur.moveToNext());
               }
 
           } catch (Exception e) {
                   System.out.println(e.getStackTrace());
           }
           return false;
    }
 
}

使用联系人操作类中的函数

ContactOperations.Insert2Contacts(getApplicationContext(),"Yildirim Kocdag", "05321000000");
if (ContactOperations.isTheNumberExistsinContacts(getApplicationContext(), "05321000000")) {
       Log.i(ContactOperations.TAG, "Exists");
} else {
       Log.i(ContactOperations.TAG, "Not Exists");
}

ContactOperations.deleteContact(getApplicationContext(), "05321000000");
if (ContactOperations.isTheNumberExistsinContacts(getApplicationContext(), "05321000000")) {
       Log.i(ContactOperations.TAG, "Exists");
} else {
       Log.i(ContactOperations.TAG, "Not Exists");
}

请勿忘记在 AndroidManifest 中使用适当的权限

读取联系人和写入联系人的权限应位于 AndroidManifest.xml 中。

<uses-permission android:name="android.permission.WRITE_CONTACTS"/>
<uses-permission android:name="android.permission.READ_CONTACTS"/>
