在edittext android中错放了错误对话框

Question

我不知道这样解决：

final Drawable d = VectorDrawableCompat.create(getResources(), R.drawable.ic_error, getTheme());
d.setBounds(0, 0,
d.getIntrinsicWidth(), d.getIntrinsicHeight());
etRegisterFormEmail.setError(getString(R.string.email_not_valid), d);

如何解决错误信息？

        if(source==oui||source==ok)
