android短信发送

短信发送

   发送短信的关键程序是通过MsmManager的sendTextMessage()方法完成，方法需要传入5个参数,依次是：收件人手机号码(String)，发送地址(String)，发送信息(String)，发送服务(PendingIntent)，送达服务(PendingIntent)，其中收件人手机号码和发送信息不能为空(null)
      GSM对短信字数有规范,70个Unicode16文字为一条
   下面代码:

package org.hwq.sms;

import android.app.Activity;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class Main extends Activity {
	EditText phone;
	EditText message;
	Button send;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        phone = (EditText) findViewById(R.id.phone);
        message = (EditText) findViewById(R.id.message);
        send = (Button) findViewById(R.id.send);
        send.setOnClickListener(new Button.OnClickListener(){

			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				String addr = phone.getText().toString();
				String msg = message.getText().toString();
				SmsManager sms = SmsManager.getDefault();
				PendingIntent pi = PendingIntent.getBroadcast(Main.this, 0, new Intent(), 0);
				sms.sendTextMessage(addr, null, msg, pi, null);
				Toast.makeText(Main.this, "发送成功", Toast.LENGTH_SHORT).show();
			}
        	
        });
    }
}

注意：需要添加发送信息权限Android.permission.SEND_SMS.

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