Java 使用基本广播接收器刷新列表视图

首先，这是我的代码

public class SMSReceiver extends BroadcastReceiver {

String from;
String msg;
long time;

@Override
public void onReceive(Context context, Intent intent) {

    Bundle bundle = intent.getExtras();
    if (bundle != null) {
        Object[] pdus = (Object[]) bundle.get("pdus");
        SmsMessage[] messages = new SmsMessage[pdus.length];
        for (int i = 0; i < pdus.length; i++) {
            // Convertir les PDUs en messages
            messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
        }

        // Enfin, traiter les messages
        for (SmsMessage message : messages) {
            from = message.getOriginatingAddress();
            msg = message.getMessageBody();
            time = message.getTimestampMillis();
            Toast.makeText(context, "Message de " + from + " : " + msg, Toast.LENGTH_LONG).show();
        }
        abortBroadcast();
    }
}

它不起作用：/

这是我的邮件列表视图

这是我的适配器

对于（int i=0；我可以详细说明您的问题吗？我的问题是，如何使用此BroadcastReceiver刷新我的listView:）您可以发布列表视图实例化代码吗？没关系，我更新了我的帖子我们仍然需要来自listView创建和自定义适配器的代码（如果您有自定义适配器，也就是说）。
