This Code may help you out to get idea about attachment:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    buttonSend = (Button) findViewById(R.id.buttonSend);

    textTo = (EditText) findViewById(R.id.editTextTo);
    textSubject = (EditText) findViewById(R.id.editTextSubject);
    textMessage = (EditText) findViewById(R.id.editTextMessage);

    buttonSend.setOnClickListener( new OnClickListener() {
        @Override
        public void onClick(View v) {
            String to = textTo.getText().toString();
            String subject = textSubject.getText().toString();
            String message = textMessage.getText().toString();

            Intent i = new Intent(Intent.ACTION_SEND);
            i.setType("plain/text");
            File data = null;

            try {
                Date dateVal = new Date();
                String filename = dateVal.toString();
                data = File.createTempFile("Report", ".csv");
                FileWriter out = (FileWriter) GenerateCsv.generateCsvFile(
                                                data, "Name,Data1");
                i.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(data));
                i.putExtra(Intent.EXTRA_EMAIL, new String[] { to });
                i.putExtra(Intent.EXTRA_SUBJECT, subject);
                i.putExtra(Intent.EXTRA_TEXT, message);
                startActivity(Intent.createChooser(i, "E-mail"));
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    });
}

public class GenerateCsv
{
    public static FileWriter generateCsvFile(File sFileName,String fileContent) 
    {
        FileWriter writer = null;

        try {
            writer = new FileWriter(sFileName);
            writer.append(fileContent);
            writer.flush();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                writer.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        return writer;
    }
}

The above code requires you add the following permission to your manifest file:
