在android 2.3.6中如何通过联系人提供程序获取联系人照片？

我有这个适用于 android 4 的版本（String email是 Gmail 地址）：

private Uri getPhotoUriFromEmail(String email) {
    Uri u = null;
    String[] projection = { ContactsContract.CommonDataKinds.Email.PHOTO_URI };
    String photoUri;
    ContentResolver cr = context.getContentResolver();
    Cursor emailCur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, projection,
            ContactsContract.CommonDataKinds.Email.ADDRESS + " = ?", 
            new String[]{email}, null);
    if (emailCur.moveToNext()) { 
        photoUri = emailCur.getString(
                emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.PHOTO_URI));
        u = Uri.parse(photoUri);
    }
    return u;
}

它的2.3.6版本是什么？ （另外，当我将 API 8 设置为最低 API 支持时，android SDK 不应该警告我使用 API 11 吗？因为它没有……）

您无需使用即可获取联系人照片 uriContactsContract.CommonDataKinds.Email.PHOTO_URI这边走：

private Uri getPhotoUriFromEmail(String email) {
    Uri u = null;
    String[] projection = { ContactsContract.CommonDataKinds.Photo.CONTACT_ID };
    String photoUri;
    ContentResolver cr = getContentResolver();
    Cursor emailCur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, 
            projection,
            ContactsContract.CommonDataKinds.Email.ADDRESS + " = ?",
            new String[]{email}, null);
    if (emailCur.moveToNext()) {
        int columnIndex = emailCur.getColumnIndex(
                              ContactsContract.CommonDataKinds.Photo.CONTACT_ID);
        long contactId = emailCur.getLong(columnIndex);

        u = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, 
                                       contactId);
        u = Uri.withAppendedPath(u, 
                                ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
    }
    return u;
}

或者，您可以使用方法获取照片流ContactsContract.Contacts .openContactPhotoInputStream(ContentResolver, Uri)这边走：

private InputStream getPhotoInputStreamFromEmail(String email) {
    Uri u = null;
    String[] projection = { ContactsContract.CommonDataKinds.Photo.CONTACT_ID };
    String photoUri;
    ContentResolver cr = getContentResolver();
    Cursor emailCur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
            projection,
            ContactsContract.CommonDataKinds.Email.ADDRESS + " = ?",
            new String[]{email}, null);
    if (emailCur.moveToNext()) {
        int columnIndex = emailCur.getColumnIndex(
                ContactsContract.CommonDataKinds.Photo.CONTACT_ID);
        long contactId = emailCur.getLong(columnIndex);

        u = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI,
                contactId);
        return ContactsContract.Contacts.openContactPhotoInputStream(cr, u);
    }
    return null;
}
