android中发送邮件

在移动互联网时代,手机邮件已不是什么新鲜事了,我们可以使用内置的Gmail引擎来发送邮件,也可以使用SMTP来发送邮件,下面用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:

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:[email protected]"));
			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:[email protected]"));
			intent.putExtra(Intent.EXTRA_EMAIL, new String[] {
					"[email protected]", "[email protected]" });
			// 抄送
			intent.putExtra(Intent.EXTRA_CC,
					new String[] { "[email protected]" });
			// 密送
			intent.putExtra(Intent.EXTRA_BCC,
					new String[] { "[email protected]" });
			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[] { "[email protected]" });
			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);
		}
	}

}
