Question

我正在发送电子邮件，但当用户从电子邮件作曲家回来时，我需要进行不同的活动，如何实现这一目标？

这是我的代码， //发送邮件

String prestartTypeString = prestartType;
String to = "juanman234@gmail.com";
String subject = "Pre-Start - "+prestartTypeString;
String message = fullName+" has sent you a Pre-Start checklist for equipment "
                  +registrationNumber+".\n" + "Please find PDF report attached.
    \n\nNeed help viewing this report\nEmail us anytime at\nhello@tiks.com.au";

Intent email = new Intent(Intent.ACTION_SEND);
email.putExtra(Intent.EXTRA_EMAIL, new String[]{ to});

email.putExtra(Intent.EXTRA_SUBJECT, subject);
email.putExtra(Intent.EXTRA_TEXT, message);

//attachment
Uri uri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(),
                                                              "generato.pdf"));
email.putExtra(Intent.EXTRA_STREAM, uri);

//need this to prompts email client only
email.setType("message/rfc822");

startActivity(Intent.createChooser(email, "Choose an Email client :"));

setResult(RESULT_OK, email);

我已经检查了

startActivityForResult（）;

但是不清楚这是否是这样做的方法，并且没有让它起作用

那么当用户从电子邮件意图回来时如何触发功能？

感谢

使用startActivityForResult（）启动活动;并覆盖以下方法

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
            //place your code here what you want to do when result is returned, in your  case go to different activity
}

当被调用的活动返回结果

时，将调用此方法
