android 通过广播获取指定联系人短信内容

在配置文件中添加以下权限

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

new一个新的广播SMSBroadcast

package aviationboss.broadcast;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.os.Message;
import android.telephony.SmsMessage;
import android.util.Log;
import aviationboss.activity.PaymentActivity;

/*
 * 判断是否接收到验证信息，并获取验证码
 */
public class SMSBroadcast extends BroadcastReceiver {

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        // TODO Auto-generated method stub
        Log.i("lwx", "receive sms");
        Bundle bundler = arg1.getExtras();//获取所拦截的短信
        if(bundler!=null){
            StringBuilder body = new StringBuilder();
            StringBuilder number = new StringBuilder();
            Object[] _pdus = (Object[]) bundler.get("pdus");
            SmsMessage[] message = new SmsMessage[_pdus.length];
            for(int i = 0;i<_pdus.length;i++){
                message[i] = SmsMessage.createFromPdu((byte[])_pdus[i]);
            }
            
            for(SmsMessage sm:message){
                body.append(sm.getDisplayMessageBody());
                number.append(sm.getDisplayOriginatingAddress());
            }
            String bodyStr = body.toString();
            String numberStr = number.toString();
            Log.i("lwx", "sms body = "+bodyStr);
            Log.i("lwx", "sms number = "+numberStr);
            if(numberStr.contains("106550101872158437")){//这里判断拦截短信的号码
                try{
                    int index_1 = bodyStr.indexOf("：");
                    int index_2 = bodyStr.indexOf("；");
                    String str = bodyStr.substring(index_1+1, index_2).trim();
                    Log.i("lwx", "str="+str);
                    int count = Integer.parseInt(str);
                    if(count>0){
                        if(PaymentActivity.handler!=null){
                            Message msg = new Message();
                            msg.what = 25;
                            msg.obj = count;
                            PaymentActivity.handler.sendMessage(msg);//将需要的内容发送给activity更新界面
                        }
                    }
                }catch(Exception e){
                    e.printStackTrace();
                }
                
            }
        }
    }
}

配置文件中添加改广播，并设置广播拦截的动作

<receiver android:name="aviationboss.broadcast.SMSBroadcast" >
      <intent-filter>
          <action android:name="android.provider.Telephony.SMS_RECEIVED" />
      </intent-filter>
</receiver>
