Android SmsManager 发送短信

SmsManager可以在后台发送短信，无需用户操作,开发者就用这个SmsManager功能在后台偷偷给SP发短信,导致用户话费被扣。必须添加android.permission.SEND_SMS权限。

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

如果短信内容过长,可以使用SmsManager.divideMessage(String text)方法自动拆分成一个ArrayList数组,再根据数组长度循环发送。

用sendMultipartTextMessage(String destinationAddress, string scAddress, ArrayList<String> parts, ArrayList<PendingIntent> sentIntents, ArrayList<PendingIntent> deliveryIntents)方法发送。

参数分别为号码，短信服务中心号码(null 即可)，短信内容，短信发送结果广播PendingIntent，短信到达广播。

下面写一个demo查移动话费余额，贴上代码：

package com.dimos.sendmessage;

import java.util.ArrayList;

import android.app.Activity;

import android.app.PendingIntent;

import android.content.Intent;

import android.content.IntentFilter;

import android.os.Bundle;

import android.telephony.SmsManager;

public class SendMessageActivity extends Activity {

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        SendReceiver receiver=new SendReceiver();

        IntentFilter filter=new IntentFilter();

        filter.addAction(SendReceiver.ACTION);

        registerReceiver(receiver,filter);

        //必须先注册广播接收器,否则接收不到发送结果

        SmsManager smsManager = SmsManager.getDefault();

        Intent intent = new Intent();

        intent.setAction(SendReceiver.ACTION);

        ArrayList<String> divideMessage = smsManager.divideMessage("ye");

        PendingIntent sentIntent = PendingIntent.getBroadcast(this, 1, intent,

                PendingIntent.FLAG_UPDATE_CURRENT);

        ArrayList<PendingIntent> sentIntents = new ArrayList<PendingIntent>();

        sentIntents.add(sentIntent);

        try {

            smsManager.sendMultipartTextMessage("10086", null,

                    divideMessage, sentIntents, null);

        } catch (Exception e) {

            e.printStackTrace();

        }

    }

}

接收器：

package com.dimos.sendmessage;

import android.app.Activity;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

public class SendReceiver extends BroadcastReceiver {

    public static final String ACTION = "action.send.sms";

    @Override

    public void onReceive(Context context, Intent intent) {

        String action = intent.getAction();

        if (ACTION.equals(action)) {

            int resultCode = getResultCode();

            if (resultCode == Activity.RESULT_OK) {

                // 发送成功

                System.out.println("发送成功！");

            } else {

                // 发送失败

                System.out.println("发送失败！");

            }

        }

    }

}
