我想使用存储在我设备上的xsd架构文件验证xml文档。这是我的示例代码：
SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
// schema file on my device
InputStream isSchema = context.getResources().openRawResource(xsd_file);
// InputStream => Source conversion
Source schemaSource = ????
Schema schema = factory.newSchema(schemaSource);
Validator validator = schema.newValidator();
validator.validate(new DOMSource(document));

You don't convert, you wrap it.
你不转换，你包装它。
Source schemaSource = new StreamSource(isSchema);
