【问题描述】：

我有这个适用于 android 4 的版本（String email 是一个 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？ （当我将 API 8 设置为我的最小 API 支持时，android SDK 也不应该警告我使用 API 11 吗？因为它没有......）

【参考方案1】：

您可以通过这种方式不使用ContactsContract.CommonDataKinds.Email.PHOTO_URI 获取联系人照片uri：

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，您可以通过这种方式使用ContactsContract.Contacts .openContactPhotoInputStream(ContentResolver, Uri) 方法获取照片流：

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;
