下面是一个发送短信的例子，主要使用了SmsManager服务，另外使用了PendingIntent

关于PendingIntent找到一些资料说明

PendingIntent实现原理和代码

Intent和PendingIntent的区别

发送短信的代码非常简单

class="language-java">package WangLi.Service.SendSms;

import class="tags" href="/tags/ANDROID.html" title=android>android.app.Activity;
import class="tags" href="/tags/ANDROID.html" title=android>android.app.PendingIntent;
import class="tags" href="/tags/ANDROID.html" title=android>android.content.Intent;
import class="tags" href="/tags/ANDROID.html" title=android>android.os.Bundle;
import class="tags" href="/tags/ANDROID.html" title=android>android.telephony.SmsManager;
import class="tags" href="/tags/ANDROID.html" title=android>android.view.View;
import class="tags" href="/tags/ANDROID.html" title=android>android.view.View.OnClickListener;
import class="tags" href="/tags/ANDROID.html" title=android>android.widget.Button;
import class="tags" href="/tags/ANDROID.html" title=android>android.widget.EditText;
import class="tags" href="/tags/ANDROID.html" title=android>android.widget.Toast;

public class SendSms extends Activity {
	EditText number, content;
	Button send;
	SmsManager sManager;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		// 获取SmsManager
		sManager = SmsManager.getDefault();
		// 获取程序界面上的两个文本框和按钮
		number = (EditText) findViewById(R.id.number);
		content = (EditText) findViewById(R.id.content);
		send = (Button) findViewById(R.id.send);
		send.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View arg0) {
				// 创建一个PendingIntent对象
				PendingIntent pi = PendingIntent.getActivity(SendSms.this, 0,
						new Intent(), 0);
				// 发送短信
				sManager.sendTextMessage(number.getText().toString(), class="tags" href="/tags/NULL.html" title=null>null,
						content.getText().toString(), pi, class="tags" href="/tags/NULL.html" title=null>null);
				// 提示短信发送完成
				Toast.makeText(SendSms.this, "短信发送完成", 8000).show();
			}
		});
	}
}

最后别忘了加上短信发送的权限

class="language-html"><uses-permission class="tags" href="/tags/ANDROID.html" title=android>android:name="class="tags" href="/tags/ANDROID.html" title=android>android.permission.SEND_SMS"/>

如果想实现短信群发的功能，其实也很简单，可以把上一篇黑名单的例子稍加改动，写一个ArrayList的集合，用来收集用户在界面上选择的电话号码，再遍历这个ArrayList，调用sendTextMessage方法，依次发送短信
