如何获取短信内容

获取短信是比较隐私的操作,需要通过广播来获取,直接上代码

1. 在mainfest中注册广播

<receiver android:name="com.smslistener.SmsReceiver">
       <intent-filter android:priority="1000">
            <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
       </intent-filter>
</receiver>

1. 创建类继承BroadcastReceiver

public class SmsReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        System.out.println("短信到来了....");
        //短信的数据是pdu的数据,必须对短信的格式很了解才可以解析短信.
        Object[] objs = (Object[]) intent.getExtras().get("pdus");
        for(Object obj:objs){
            SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) obj);
            String body = smsMessage.getMessageBody();
            String sender = smsMessage.getOriginatingAddress();
            System.out.println("body:"+body);
            System.out.println("sender:"+sender);
            abortBroadcast();
        }
    }
}

Google官方的源码是这么写的

public static final SmsMessage[] getMessagesFromIntent(
                    Intent intent) {
                Object[] messages = (Object[]) intent.getSerializableExtra("pdus");
                byte[][] pduObjs = new byte[messages.length][];

                for (int i = 0; i < messages.length; i++) {
                    pduObjs[i] = (byte[]) messages[i];
                }
                byte[][] pdus = new byte[pduObjs.length][];
                int pduCount = pdus.length;
                SmsMessage[] msgs = new SmsMessage[pduCount];
                for (int i = 0; i < pduCount; i++) {
                    pdus[i] = pduObjs[i];
                    msgs[i] = SmsMessage.createFromPdu(pdus[i]);
                }
                return msgs;
            }

可以调用getMessagesFromIntent()函数来获取短信数组,for循坏来获取

就说这么多,短信的格式是PDU格式的,大家想了解的话可以去学习一下,这里就不做介绍了,希望能帮到你!
