重庆阿里云代理商：android 收发短信监听

在Android平台上实现收发短信监听可以通过注册BroadcastReceiver来实现。以下是一个简单的示例代码：

1. 在AndroidManifest.xml文件中添加权限声明：

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

2. 创建一个BroadcastReceiver类来监听收到的短信：

public class SmsBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {
            Bundle bundle = intent.getExtras();
            if (bundle != null) {
                Object[] pdus = (Object[]) bundle.get("pdus");
                for (Object pdu : pdus) {
                    SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) pdu);
                    String messageBody = smsMessage.getMessageBody();
                    String sender = smsMessage.getOriginatingAddress();
                    // 处理收到的短信
                    // 可以进行一些逻辑处理，比如发送短信到指定号码
                }
            }
        }
    }
}

3. 在Activity或Service中注册BroadcastReceiver：

public class MainActivity extends AppCompatActivity {

    private SmsBroadcastReceiver smsBroadcastReceiver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        smsBroadcastReceiver = new SmsBroadcastReceiver();
        IntentFilter intentFilter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
        registerReceiver(smsBroadcastReceiver, intentFilter);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        unregisterReceiver(smsBroadcastReceiver);
    }
}

通过以上步骤，你就可以在Android应用中实现收发短信监听的功能了。需要注意的是，Android 6.0及以上版本需要动态申请权限才能正常接收短信。

在Android平台上，要实现短信的收发监听，可以通过注册BroadcastReceiver来接收系统发出的短信相关广播。以下是一个简单的示例代码：

1. 在AndroidManifest.xml中添加权限和注册BroadcastReceiver：

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

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

2. 创建BroadcastReceiver类SmsReceiver.java并实现短信的收发监听逻辑：

public class SmsReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {
            Bundle bundle = intent.getExtras();
            if (bundle != null) {
                Object[] pdus = (Object[]) bundle.get("pdus");
                if (pdus != null) {
                    for (Object pdu : pdus) {
                        SmsMessage message = SmsMessage.createFromPdu((byte[]) pdu);
                        String sender = message.getDisplayOriginatingAddress();
                        String messageBody = message.getMessageBody();
                        
                        // 处理收到的短信
                        Log.d("SmsReceiver", "Received message from: " + sender + ", content: " + messageBody);
                    }
                }
            }
        }
    }
}

以上代码通过注册SmsReceiver广播接收器来监听系统发出的短信广播，并在onReceive方法中读取短信发送者和内容。注意要在AndroidManifest.xml中声明相应的权限并注册BroadcastReceiver，以确保应用可以正常接收短信。
