在android中发送邮件

一个简单示例来演示邮件的发送，包括单方发送邮件、多方发送邮件以及抄送邮件，密送邮件，发送附件等。代码如下：</span>

Activity：

package com.home;    import android.app.Activity;  import android.content.Intent;  import android.net.Uri;  import android.os.Bundle;  import android.view.View;  import android.view.View.OnClickListener;  import android.widget.Button;    public class SendEmailActivity extends Activity implements OnClickListener {   private Button sendBtn;   private Button sendToManyBtn;   private Button sendAttachmentBtn;     @Override   protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.main);    sendBtn = (Button) findViewById(R.id.main_btn_send);    sendToManyBtn = (Button) findViewById(R.id.main_btn_send_many);    sendAttachmentBtn = (Button) findViewById(R.id.main_btn_send_attachment);    sendBtn.setOnClickListener(this);    sendToManyBtn.setOnClickListener(this);    sendAttachmentBtn.setOnClickListener(this);   }     @Override   public void onClick(View v) {    if (v == sendBtn) {     Intent intent = new Intent(Intent.ACTION_SENDTO);     intent.setData(Uri.parse("mailto:+297890152@qq.com"));     intent.putExtra(Intent.EXTRA_SUBJECT, "这是单方发送的邮件主题");     intent.putExtra(Intent.EXTRA_TEXT, "这是单方发送的邮件内容");     startActivity(intent);    }    if (v == sendToManyBtn) {     Intent intent = new Intent(Intent.ACTION_SENDTO);     intent.setData(Uri.parse("mailto:297890152@qq.com"));     intent.putExtra(Intent.EXTRA_EMAIL, new String[] {       "313766045@qq.com", "980324510@qq.com" });     // 抄送     intent.putExtra(Intent.EXTRA_CC,       new String[] { "981413230@qq.com" });     // 密送     intent.putExtra(Intent.EXTRA_BCC,       new String[] { "1316106487@qq.com" });     intent.putExtra(Intent.EXTRA_SUBJECT, "这是多方发送的邮件主题");     intent.putExtra(Intent.EXTRA_TEXT, "这是多方发送的邮件内容");     startActivity(intent);    }    if (v == sendAttachmentBtn) {     Intent intent = new Intent(Intent.ACTION_SEND);     intent.putExtra(Intent.EXTRA_EMAIL,       new String[] { "297890152@qq.com" });     intent.putExtra(Intent.EXTRA_SUBJECT, "这是包含附件的邮件主题");     intent.putExtra(Intent.EXTRA_TEXT, "这是包含附件的邮件内容");     intent.putExtra(Intent.EXTRA_STREAM, Uri.parse(""));     intent.setType("text/plain");     startActivity(intent);    }   }    }
