英文:
Problem when sending email from Android app
问题
以下是翻译好的内容：
我正试图从我的Android应用程序直接发送电子邮件给收件人。但是当我点击发送时，什么都不会发生。成功的提示信息也不会出现。
我使用了以下这些类：JSSEProvider、ByteArrayDatasource、MailSender。
这是我的主要代码：
Send_mail.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if ("".equals(recipient_mail.getText().toString().trim())) {
Toast.makeText(FirstActivity.this, "请输入收件人邮箱", Toast.LENGTH_SHORT).show();
} else {
new Thread(new Runnable() {
@Override
public void run() {
try {
MailSender sender = new MailSender(sender_mail.getText().toString(),
mail_password.getText().toString());
sender.sendMail(Subject.getText().toString(), Text.getText().toString(),
sender_mail.getText().toString(), recipient_mail.getText().toString());
Toast.makeText(context, "发送成功！", Toast.LENGTH_SHORT).show();
} catch (Exception e) {
Log.e("SendMail", e.getMessage(), e);
}
}
}).start();
}
}
});
这是我的对话框活动：

在线程内部无法显示 Toast 消息，您需要切换到主线程来实现此操作。因此，请将您的 Toast 消息替换为以下代码：
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(FirstActivity.this, "成功！", Toast.LENGTH_SHORT).show();
}
});
英文:
You can not show a Toast message within a thread, you need to reach the main thread to achieve this. So, replace your toast message with this
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(FirstActivity.this, "Success!", Toast.LENGTH_SHORT).show();
}
});
