有关Android发送E-mail

传递信息的Action是Intent.ACTION_SEND。

代码如下：

Intent sendEmailIntent = new Intent(Intent.ACTION_SEND);

String subject = "subject ";
String body = "body ";
String[] extra = new String[]    {"111@bbb.com","222@bbb.com","333@bbb.com"};

sendEmailIntent .putExtra(Intent.EXTRA_EMAIL, extra[0]);//发送目标
sendEmailIntent .putExtra(Intent.EXTRA_CC, extra[1]); //抄送
sendEmailIntent .putExtra(Intent.EXTRA_BCC, extra[2]); //暗送
sendEmailIntent .putExtra(Intent.EXTRA_SUBJECT, subject);//标题
sendEmailIntent .putExtra(Intent.EXTRA_TEXT, body);//内容

sendEmailIntent .setType("text/plain");//指定内容是纯文本
//sendEmailIntent .setType("image/png");//指定内容是图片

startActivity(sendEmailIntent);
//也可自定义选择器
//startActivity(Intent.createChooser(sendEmailIntent, "请选择发送软件")); 

写成方法：

private static void sendEmail(Context context, String[] to, String subject, 
      String body) { 

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

    if (to != null) { 
      email.putExtra(android.content.Intent.EXTRA_EMAIL, to); 
    } 
    if (subject != null) { 
      email.putExtra(android.content.Intent.EXTRA_SUBJECT, subject); 
    } 
    if (body != null) { 
      email.putExtra(android.content.Intent.EXTRA_TEXT, body); 
    } 
    
    email.setType("text/plain"); 
   
    context.startActivity(Intent.createChooser(emailIntent , "请选择发送软件")); 

  } 

若用到读写权限：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
