电子邮件作曲家在android系统 [英] Email Composer in android

问题描述

在我的应用我想发送电子邮件给一个account.in点击一个按钮event.i用下面的code。这有例外

 公共无效的onClick（视图v）{
             sendEmail（背景下，新的String [] {[e-mail]}，发送电子邮件，测试电子邮件，我的身体）;
        }        私人无效sendEmail（上下文的背景下，字符串[] recipientList，
                主题字符串，字符串的身体，字符串名称）{
            意图emailIntent =新意图（android.content.Intent.ACTION_SEND）;
            emailIntent.setType（纯/文）;
            emailIntent.putExtra（android.content.Intent.EXTRA_EMAIL，recipientList）;
            emailIntent.putExtra（android.content.Intent.EXTRA_SUBJECT，学科）;
            emailIntent.putExtra（android.content.Intent.EXTRA_TEXT，体）;
            emailIntent.addFlags（Intent.FLAG_ACTIVITY_MULTIPLE_TASK）;            尝试
            {
            context.startActivity（Intent.createChooser（emailIntent，标题））;            }赶上（例外五）
            {
                的System.out.println（E）;
            }
        }
 

例外，我越来越为

 03-19 19：13：19.553：我/的System.out（2010）：android.util.AndroidRuntimeException：从活动上下文之外调用startActivity（）需要FLAG_ACTIVITY_NEW_TASK旗。
 

解决方案

它的正常工作。首先要配置一个电子邮件客户端模拟器。在此输入code

 公共无效的onClick（视图v）{            // TODO自动生成方法存根            意图emailIntent =新意图（android.content.Intent.ACTION_SEND）;            字符串aEmailList [] = {[e-mail]};
            //字符串aEmailCCList [] = {};
            //字符串aEmailBCCList [] = {};            emailIntent.putExtra（android.content.Intent.EXTRA_EMAIL，aEmailList）;
            //emailIntent.putExtra(android.content.Intent.EXTRA_CC，aEmailCCList）;
            //emailIntent.putExtra(android.content.Intent.EXTRA_BCC，aEmailBCCList）;            emailIntent.putExtra（android.content.Intent.EXTRA_SUBJECT，我的主题）;            emailIntent.setType（信息/ RFC822）;
            emailIntent.putExtra（android.content.Intent.EXTRA_TEXT，我的消息体。）;
               尝试
               {
            startActivity（emailIntent）;
               }赶上（android.content.ActivityNotFoundException前）{
                Toast.makeText（about.this，有没有安装的电子邮件客户端，Toast.LENGTH_SHORT）.show（）;
            }
               赶上（例外五）{的System.out.println（E）;}
        }
 

In my application i want send a email to one account.in one button click event.i used the below code . this have exception

public void onClick(View v) {
             sendEmail(context, new String[]{"[e-mail]"}, "Sending Email", "Test Email", "I am body");
        }

        private void sendEmail(Context context, String[] recipientList,
                String subject, String body, String title) {
            Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
            emailIntent.setType("plain/text");
            emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, recipientList);
            emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
            emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, body);
            emailIntent.addFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK);

            try
            {
            context.startActivity(Intent.createChooser(emailIntent, title));

            }catch(Exception e)
            {
                System.out.println(e);
            }   
        }

The exception I am getting as

 "03-19 19:13:19.553: I/System.out(2010): android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag.

解决方案

It's working fine. first thing to configure a email client for your emulator.enter code here

public void onClick(View v) {

            // TODO Auto-generated method stub

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

            String aEmailList[] = { "[e-mail]" };
            //String aEmailCCList[] = { ""};
            //String aEmailBCCList[] = { "" };

            emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, aEmailList);
            //emailIntent.putExtra(android.content.Intent.EXTRA_CC, aEmailCCList);
            //emailIntent.putExtra(android.content.Intent.EXTRA_BCC, aEmailBCCList);

            emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "My subject");

            emailIntent.setType("message/rfc822");
            emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "My message body.");
               try
               {
            startActivity(emailIntent);
               }catch (android.content.ActivityNotFoundException ex) {
                Toast.makeText(about.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
            }


               catch(Exception e){ System.out.println(e);}
        }
