今天来记录一下一个短信发送器,并且能监控短信是否发送成功

首先如果在我们程序中要发送短信必须先声明android.permission.SEND_SMS的权限

第二发送短信,我们需要一个SmsManager的类帮助我们发送短信,注意:这个类是在android.telephony.SmsManager包下的

SmsManager smsManager=SmsManager.getDefault();

创建实例,调用

smsManager.sendTextMessage(String destinationAddress, String scAddress, 

String text, PendingIntent sentIntent,

PendingIntent deliveryIntent);

来发送短信,值得注意的是第一个参数是短信接收者的手机号码,第二个参数是不常用不用管,第三个参数是短信的内容,

第四个参数是一个PendingIntent,短信发送成功,SmsManager会利用这个PendingIntent来发送一个广播(此广播中的

ResultCode会告诉广播接受者,此条短信是否发送成功),官方的解释如下: if not NULL this PendingIntent is broadcast when the

message is successfully sent, or failed. The result code will be Activity.RESULT_OK for success, or one of these errors:RESULT_ERROR_GENERIC_FAILURE、

RESULT_ERROR_RADIO_OFF、RESULT_ERROR_NULL_PDU。

 

代码如下:

package com.jsako.sendsms;import android.app.Activity;import android.app.PendingIntent;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.IntentFilter;import android.os.Bundle;import android.telephony.SmsManager;import android.text.TextUtils;import android.view.View;import android.widget.EditText;import android.widget.Toast;public class MainActivity extends Activity {    private EditText et_phone;    private EditText et_msg;    private IntentFilter sendFilter;    private SendStatusReceiver sendStatusReceiver;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        et_phone = (EditText) findViewById(R.id.et_phone);        et_msg = (EditText) findViewById(R.id.et_msg);        sendFilter =new IntentFilter("SEND_SMS");        sendStatusReceiver=new SendStatusReceiver();
     //动态注册广播接收者 registerReceiver(sendStatusReceiver, sendFilter); } @Override
protected void onDestroy() { super.onDestroy();
    //取消注册广播接收者 unregisterReceiver(sendStatusReceiver); sendStatusReceiver
=null; } public void send(View view){ String phone=et_phone.getText().toString().trim(); String msg=et_msg.getText().toString().trim(); if(TextUtils.isEmpty(phone)||TextUtils.isEmpty(msg)){ Toast.makeText(this,"手机号码或短信内容不能为空", 0).show(); } SmsManager smsManager=SmsManager.getDefault(); Intent intent=new Intent("SEND_SMS");
     //获得一个能发出广播的意图 PendingIntent pi
=PendingIntent.getBroadcast(this, 0, intent, 0); smsManager.sendTextMessage(phone, null, msg, pi,null ); } private class SendStatusReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if(this.getResultCode()==RESULT_OK){
          //如果结果集为RESULT_OK说明消息发送成功 Toast.makeText(getApplicationContext(),
"发送成功", 0).show(); }else{ Toast.makeText(getApplicationContext(), "发送失败", 0).show(); } } }}
