Android调用系统的发邮件功能的小例子

代码如下:
package com.example.myapi.email;

import java.util.ArrayList;
import java.util.List;

import android.content.Context;
import android.content.Intent;
import android.net.Uri;

public class SendEmailUtils {
    private SendEmailUtils(){}
    private static SendEmailUtils instance;
    public static SendEmailUtils getInstance(){
        synchronized (SendEmailUtils.class) {
            if(instance == null){
                instance = new SendEmailUtils();
            }
        }
        return instance;
    }
   
    public void sendEmail(Context context){
        Intent intent = new Intent();
        intent.setData(Uri.parse("mailto:"));
       
        intent.putExtra(Intent.EXTRA_SUBJECT, "别紧张，这仅仅是一个测试！");
       
        intent.putExtra(Intent.EXTRA_TEXT, "测试打开系统邮箱并将发送的标题和内容自动填充到邮箱，并发送邮件，");
        //开始调用
        context.startActivity(intent);
    }
   
    public void sendEmailDuo(Context context){
        Intent intent = new Intent(Intent.ACTION_SEND);
//        intent.setData(Uri.parse("mailto:"));
        String[] tos = { "yw.1@163.com" };
        String[] ccs = { "yw.2@163.com" };
        String[] bccs = {"yw.3@163.com"};
        intent.putExtra(Intent.EXTRA_EMAIL, tos); //收件者
        intent.putExtra(Intent.EXTRA_CC, ccs); //抄送这
        intent.putExtra(Intent.EXTRA_BCC, bccs); //密送这
        intent.putExtra(Intent.EXTRA_TEXT, "邮件内容");
        intent.putExtra(Intent.EXTRA_SUBJECT, "邮件标题");

        intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///mnt/sdcard/a.jpg"));
        intent.setType("image
    public void sendFujian(Context conext){
        Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
        String[] tos = { "way.ping.li@gmail.com" };
        String[] ccs = { "way.ping.li@gmail.com" };
        intent.putExtra(Intent.EXTRA_EMAIL, tos);
        intent.putExtra(Intent.EXTRA_CC, ccs);
        intent.putExtra(Intent.EXTRA_TEXT, "body");
        intent.putExtra(Intent.EXTRA_SUBJECT, "subject");

        List<Uri> imageUris = new ArrayList<Uri>();
        imageUris.add(Uri.parse("file:///mnt/sdcard/a.jpg"));
        imageUris.add(Uri.parse("file:///mnt/sdcard/b.jpg"));
        intent.putExtra(Intent.EXTRA_STREAM, imageUris);
        intent.setType("image/*");
        intent.setType("message/rfc882");
        Intent.createChooser(intent, "Choose Email Client");
        conext.startActivity(intent);
    }
}
