在Android SDK上查找包含cyrillics的不区分大小写的电话名

Question

我正试图使用这个简单的查询来获取联系人列表，它完全可以忽略输入过滤器的情况，直到我尝试搜索包含cyrillics的名称：

Cursor c = this.getContext().getContentResolver().query(Phone.CONTENT_URI,
            PHONE_PROJECTION, Phone.DISPLAY_NAME + " LIKE '%"+filter+"%'", null,     Phone.LAST_TIME_CONTACTED + " DESC");

问题是，这段代码只为精确匹配而返回包含cyrillic的名称，因此它对cyrillic区分大小写。我希望搜索对cyrillics也不区分大小写。应用程序在最小SDK 2.1 上运行

系统本身（在4.0 ICS上测试）能够在联系人列表中进行不区分大小写的搜索（默认系统应用程序-People）。

谢谢你的回复。

修复了您的代码，确保处理好剩下的我举了个例子这是固定代码：

 String name = "contact_name_to_search_for"
 Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI,
            null,"DISPLAY_NAME" + " LIKE '%"+name+"%'", null,
            ContactsContract.CommonDataKinds.Phone.LAST_TIME_CONTACTED + " DESC");

这是我制作的完整处理代码，例如

String name = "contact_name_to_search_for"
        ContentResolver cr = getContentResolver();
    Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI,
            null,"DISPLAY_NAME" + " LIKE '%"+name+"%'", null,
            ContactsContract.CommonDataKinds.Phone.LAST_TIME_CONTACTED + " DESC");
    if (cursor.moveToFirst()) {
        String contactId =
                cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)).toLowerCase();
        Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId.toLowerCase(), null, null);
        while (phones.moveToNext()) {
            String number = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
            int type = phones.getInt(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));
            switch (type) {
                case ContactsContract.CommonDataKinds.Phone.TYPE_HOME:
                    Toast.makeText(getApplicationContext(), number+" Home number",Toast.LENGTH_SHORT ).show();
                    break;
                case ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE:
                    Toast.makeText(getApplicationContext(), number+" Mobile number",Toast.LENGTH_SHORT ).show();
                    break;
                case ContactsContract.CommonDataKinds.Phone.TYPE_WORK:
                    Toast.makeText(getApplicationContext(), number+" Work number",Toast.LENGTH_SHORT ).show();
                    break;
            }
        }
        phones.close();
    }
    cursor.close();
