adnroid 监听收到的短信并根据短信内容进行回复短信

定义一个广播接收器

public class SMSReceiver extends BroadcastReceiver {
    private SmsManager smsManager;

    @Override
    public void onReceive(Context arg0, Intent intent) {
        
        if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")){
            
            SharedPreferences sp = arg0.getSharedPreferences("MSG_SEND_RESULT", Activity.MODE_PRIVATE);
            SharedPreferences.Editor editor = sp.edit();
            

            smsManager = SmsManager.getDefault();
            
            Object[] pdus=(Object[])intent.getExtras().get("pdus");
            
            SmsMessage[] message=new SmsMessage[pdus.length];
            
            for(int i=0;i<pdus.length;i++){
                message[i]=SmsMessage.createFromPdu((byte[])pdus[i]);
                
                String msgAddr = message[i].getDisplayOriginatingAddress();
                String msgContent = message[i].getDisplayMessageBody();
                
                //自动回复短信
                String content = "";
                int count = 0;
                if(msgContent.trim().equals("1")){//android
                    content = "android";
                    smsManager.sendTextMessage(msgAddr, null, content, null, null);
                    count = sp.getInt("android", 0)+1;
                    editor.putInt("android", count);
                    editor.apply();
                }else if(msgContent.trim().equals("2")){//ios
                    content = "ios";
                    smsManager.sendTextMessage(msgAddr, null, content, null, null);
                    count = sp.getInt("iphone", 0)+1;
                    editor.putInt("iphone", count);
                    editor.apply();
                }
            }
        }
    }
}

添加权限：

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

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