如何在Android中发送电子邮件到多个收件人？ [英] How to send email to multiple recepients in android?

问题描述

我是Android的新手。请帮帮我。我无法向多个收件人发送电子邮件。
这是我的代码。

  public class SendEmailActivity extends Activity {
 
 EditText subject_ed， message_ed; 
 TextView subject_tv，message_tv; 
按钮send_btn; 
 
 ArrayList< String>的emailList; 
 ArrayList< Integer> IDLIST; 
 int eventId; 
 @Override 
 protected void onCreate（Bundle savedInstanceState）{
 // TODO自动生成的方法存根
 super.onCreate（savedInstanceState）; 
 setContentView（R.layout.contacts_email_sms_layout）; 
 setupViews（）; 
 Intent intent = getIntent（）; 
 Bundle b = intent.getExtras（）; 
 eventId = b.getInt（EventId）; //事件id 
 idList = b.getIntegerArrayList（IdList）; // Ids列表
 emailList = b.getStringArrayList（ EmailList）; //电子邮件ID列表
 buttonListeners（）; 
} 
 
 public void setupViews（）
 {
 subject_ed =（EditText）findViewById（R.id.ed_subject_email）; 
 message_ed =（EditText）findViewById（R.id.ed_msg_body）; 
 subject_tv =（TextView）findViewById（R.id.tv_subject_email）; 
 message_tv =（TextView）findViewById（R.id.tv_msg_body）; 
 send_btn =（Button）findViewById（R.id.btn_send_sms_email）; 
} 
 
 public void buttonListeners（）
 {
 send_btn.setOnClickListener（new OnClickListener（）{
 
 @Override 
 public void onClick（View v）{
 // TODO自动生成的方法stub 
 Toast.makeText（getApplicationContext（），Email sent，Toast.LENGTH_LONG）.show（）; 
 // String to = textTo.getText（）。toString（）; 
 String subject = subject_ed.getText（）。toString（）; 
 String message = message_ed.getText（）。toString（）; 
 Object [] to = emailList.toArray（）; 
 // for（int i = 0; i< = emailList.size（）; i ++）
 //// {
 //// 
 // String to = emailList.get（0）; 
 //// 
 ////} 
 
 
 
 Intent email = new Intent（Intent.ACTION_SEND）; 
（int i = 0; i  {
 Log.i（String is，（String）to [i]）; 
 // String [] str =（String []）to [i]; 
 email.putExtra（Intent.EXTRA_EMAIL，，+（String）to [i] +'）; 
} 
 
 email.putExtra（Intent.EXTRA_SUBJECT，subject）; 
 email.putExtra（Intent.EXTRA_TEXT，message）; 
 
 //需要这个来提示电子邮件客户端
 email.setType（message / rfc822）; 
 
 startActivity（Intent.createChooser（email，Choose a Email client：））; 
 // finish（）; 
} 
}）; 
} 
 
} 
  

解决方案

首先，从List到String []的转换是错误的，您需要执行如下操作。

 列表< String> list = new ArrayList< String>（）; 
 String [] arrayOfStrings = list.toArray（new String [list.size（）]）; 
  

接下来你需要提到android.Content.Intent如下..

所以最后你需要改变如下

  ArrayList< String>的emailList; 
 emailList = b.getStringArrayList（EmailList）; 
 String [] emailArray; 
 
 Intent email = new Intent（android.content.Intent.ACTION_SEND）; （int i = 0; i< to.length; i ++）{
 Log.i（String is，（String）to [i]）; 
 
 
 email.putExtra（android.content.Intent.EXTRA_EMAIL，
 emailList.toArray（new String [emailList.size（）]））; 
} 
 email.putExtra（android.content.Intent.EXTRA_SUBJECT，subject）; 
 email.putExtra（android.content.Intent.EXTRA_TEXT，message）; 
 email.setType（message / rfc822）; //或email.setType（text / plain）; 
 
 startActivity（Intent.createChooser（email，Choose a Email client：））; 
  

I'm a newbie in android. Please help me. I'm not able to send email to multiple recipients. Here is my code.

public class SendEmailActivity extends Activity{

EditText subject_ed,message_ed;
TextView subject_tv,message_tv;
Button send_btn;

 ArrayList<String> emailList;
 ArrayList<Integer> idList;
 int eventId;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.contacts_email_sms_layout);
    setupViews();
    Intent intent = getIntent();
    Bundle b = intent.getExtras();
    eventId =  b.getInt("EventId");//event id
    idList = b.getIntegerArrayList("IdList");//list of Ids
    emailList = b.getStringArrayList("EmailList");//list of email ids
    buttonListeners();
}

public void setupViews()
{
    subject_ed = (EditText)findViewById(R.id.ed_subject_email);
    message_ed = (EditText)findViewById(R.id.ed_msg_body);
    subject_tv = (TextView)findViewById(R.id.tv_subject_email);
    message_tv = (TextView)findViewById(R.id.tv_msg_body);
    send_btn = (Button)findViewById(R.id.btn_send_sms_email);
}               

public void buttonListeners()
{
    send_btn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Toast.makeText(getApplicationContext(), "Email sent",Toast.LENGTH_LONG).show();
            // String to = textTo.getText().toString();
              String subject = subject_ed.getText().toString();
              String message = message_ed.getText().toString();
            Object[] to =  emailList.toArray();
//            for(int i = 0; i<=emailList.size(); i++)
////                  {
////                      
//                  String  to=   emailList.get(0);
////                     
////                  }



              Intent email = new Intent(Intent.ACTION_SEND);
              for(int i = 0; i < to.length; i++)
                {
                    Log.i("String is", (String)to[i]);
                    //String[] str = (String[])to[i];
                     email.putExtra(Intent.EXTRA_EMAIL,",'" +(String)to[i] + "'");
                }

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

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

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

}

解决方案

First your conversion from List to String[] is wrong you need to do as follows..

List<String> list = new ArrayList<String>();
String[] arrayOfStrings = list.toArray(new String[list.size()]);

And next thing is you need to mention android.Content.Intent as follows..

So finally you need to change as follows

ArrayList<String> emailList;
emailList = b.getStringArrayList("EmailList");
String[] emailArray;

Intent email = new Intent(android.content.Intent.ACTION_SEND);

for(int i = 0; i < to.length; i++){
    Log.i("String is", (String)to[i]);
    email.putExtra(android.content.Intent.EXTRA_EMAIL, 
                   emailList.toArray(new String[emailList.size()]));
}
email.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
email.putExtra(android.content.Intent.EXTRA_TEXT, message);    
email.setType("message/rfc822"); //or email.setType("text/plain");

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