绵阳阿里云代理商：android 开发短信通知栏

实现步骤：

1.在AndroidManifest.xml中添加权限：

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

2.创建BroadcastReceiver，监听短信：

public class SmsReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle bundle = intent.getExtras();
        if (bundle != null) {
            Object[] pdus = (Object[]) bundle.get("pdus");
            if (pdus != null && pdus.length > 0) {
                for (Object pdu : pdus) {
                    SmsMessage message = SmsMessage.createFromPdu((byte[]) pdu);
                    String content = message.getMessageBody();
                    String sender = message.getOriginatingAddress();

                    // 处理短信内容
                    // ...

                    // 在通知栏上展示短信内容
                    NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
                    NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
                    builder.setSmallIcon(R.mipmap.ic_launcher)
                            .setContentTitle(sender)
                            .setContentText(content)
                            .setAutoCancel(true)
                            .setDefaults(Notification.DEFAULT_ALL);
                    manager.notify(1, builder.build());
                }
            }
        }
    }
}

3.在AndroidManifest.xml中注册BroadcastReceiver，同时指定接受的Intent：

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

通过以上步骤，即可实现接收短信并在通知栏上展示短信内容的功能。

实现步骤：

1. 在 AndroidManifest.xml 文件中，添加权限：

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

2. 创建一个 BroadcastReceiver 类，用于接收短信广播并在通知栏显示短信：

public class SmsReceiver extends BroadcastReceiver {

    private static final String TAG = "SmsReceiver";

    @Override
    public void onReceive(Context context, Intent intent) {
        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.getOriginatingAddress();
                    String body = message.getMessageBody();
                    showNotification(context, sender, body);
                }
            }
        }
    }

    private void showNotification(Context context, String sender, String body) {
        NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
        builder.setContentTitle(sender);
        builder.setContentText(body);
        builder.setSmallIcon(android.R.drawable.ic_dialog_email);

        Intent intent = new Intent(context, MainActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        builder.setContentIntent(pendingIntent);

        NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        manager.notify(0, builder.build());
    }
}

3. 在 AndroidManifest.xml 文件中，声明该 BroadcastReceiver：

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

4. 在 MainActivity 中，请求 RECEIVE_SMS 权限：

if (ContextCompat.checkSelfPermission(this, Manifest.permission.RECEIVE_SMS) != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.RECEIVE_SMS}, 1);
}

以上就是 Android 开发短信通知栏的实现步骤，希望能帮到你。
