android - 如何在android中以编程方式删除联系人

Question

我尝试使用以下代码删除指定号码的联系人:

private void removeContact(Context context, String phone) {
    //context.getContentResolver().delete(Contacts.Phones.CONTENT_URI, phone, null);
    context.getContentResolver().delete(Contacts.Phones.CONTENT_URI,
          Contacts.PhonesColumns.NUMBER+"=?", new String[] {phone});
}

但我得到了这个异常(exception):

java.lang.UnsupportedOperationException: Cannot delete that URL: content://contacts/phones
    at android.database.DatabaseUtils.readExceptionFromParcel(DatabaseUtils.java:130)
    at android.database.DatabaseUtils.readExceptionFromParcel(DatabaseUtils.java:110)
    at android.content.ContentProviderProxy.delete(ContentProviderNative.java:362)
    at android.content.ContentResolver.delete(ContentResolver.java:386)

您能告诉我如何解决我的问题吗？

谢谢。

要删除所有联系人，请使用以下代码:

ContentResolver cr = getContentResolver();
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
            null, null, null, null);
    while (cur.moveToNext()) {
        try{
            String lookupKey = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
            Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI, lookupKey);
            System.out.println("The uri is " + uri.toString());
            cr.delete(uri, null, null);
        }
        catch(Exception e)
        {
            System.out.println(e.getStackTrace());
        }
    }

要删除任何特定联系人，请修改查询

cr.delete(uri, null, null);

希望对你有帮助!
