發送電子郵件后如何敬酒？在 onCreate() 方法和 email.setOnClickListener(new View.OnClickListener()...            else            {                loadingBar.setTitle("Sending Email");                loadingBar.setMessage("Please wait! We are sending your message to the support department.");                loadingBar.show();                Intent sendEmail = new Intent(android.content.Intent.ACTION_SEND);                sendEmail.setType("plain/text");                sendEmail.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{"[email protected]"});                sendEmail.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);                sendEmail.putExtra(android.content.Intent.EXTRA_TEXT,                        "Name: " + name + '\n' + "Email: " + email + '\n' + "Message: " + '\n' + message);                startActivity(Intent.createChooser(sendEmail, "Send mail..."));            }            Toast.makeText(ContactUs.this, "Your message has been sent successfully.", Toast.LENGTH_SHORT).show();        }    });如下圖所示，Toast 消息出現并帶有電子郵件彈出窗口。
