使用此

    String adress = ((EditText)findViewById(R.id.from)).getText();
    String subject = ((EditText)findViewById(R.id.et_subject)).getText();
    String message = ((EditText)findViewById(R.id.et_message)).getText();

    Intent i = new Intent(Intent.ACTION_SEND);
    i.setType("message/rfc822");
    i.putExtra(Intent.EXTRA_EMAIL  , new String[]{adress});
    i.putExtra(Intent.EXTRA_SUBJECT, subject);
    i.putExtra(Intent.EXTRA_TEXT   , message);
    try {
        startActivity(Intent.createChooser(i, "Send mail..."));
    } catch (android.content.ActivityNotFoundException ex) {
        Toast.makeText(MyActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
    }
