嗨，我是 java 新手，这将是我第一次使用进度条。例如，我尝试使用 google，但不知道如何在 SMSlib sendmessage java 类上使用它。

import javax.swing.SwingWorker;
import org.smslib.AGateway;
import org.smslib.IOutboundMessageNotification;
import org.smslib.Library;
import org.smslib.OutboundMessage;
import org.smslib.Service;
import org.smslib.modem.SerialModemGateway;

public class SendMessage
{
    public void doIt(String recipient, String message) throws Exception
    {
        OutboundNotification outboundNotification = new OutboundNotification();
        System.out.println("Example: Send message from a serial gsm modem.");
        System.out.println(Library.getLibraryDescription());
        System.out.println("Version: " + Library.getLibraryVersion());
        SerialModemGateway gateway = new SerialModemGateway("modem.com1", "COM54", 115200, "Wavecom", "m1306b");
        gateway.setInbound(true);
        gateway.setOutbound(true);
        gateway.setSimPin("");
        gateway.setSmscNumber("+639170000130");
        Service.getInstance().setOutboundMessageNotification(outboundNotification);
        Service.getInstance().addGateway(gateway);
        Service.getInstance().startService();
        System.out.println();
        System.out.println("Modem Information:");
        System.out.println("  Manufacturer: " + gateway.getManufacturer());
        System.out.println("  Model: " + gateway.getModel());
        System.out.println("  Serial No: " + gateway.getSerialNo());
        System.out.println("  SIM IMSI: " + gateway.getImsi());
        System.out.println("  Signal Level: " + gateway.getSignalLevel() + " dBm");
        System.out.println("  Battery Level: " + gateway.getBatteryLevel() + "%");
        System.out.println();
        // Send a message synchronously.
        OutboundMessage msg = new OutboundMessage(recipient,message);
        Service.getInstance().sendMessage(msg);
        System.out.println(msg);

        Service.getInstance().stopService();
    }

    public class OutboundNotification implements IOutboundMessageNotification
    {
        public void process(AGateway gateway, OutboundMessage msg)
        {
            System.out.println("Outbound handler called from Gateway: " + gateway.getGatewayId());
            System.out.println(msg);
        }
    }


}

顺便说一句，我使用 netbeans 作为我的 IDE。

在这里，您有一个SwingWorker带有进度条的完整示例。摇摆工人示例。

基本上，您使用 aSwingworker在后台线程中运行繁重的任务，以免阻塞您的 gui。

一个简单的例子：

public class Worker extends SwingWorker<Void, String> {

    @Override
    protected void doInBackground() throws Exception {
       //here you make heavy task this is running in another thread not in EDT
       // call your smslib
       setProgress(0);
       // do some another operation
       setProgress(43);
       // another operation
       setProgress(89);
       .
       .
    }
}

在您拥有progressBar的客户端代码中：

SwingWorker myWorker = new Worker();
myWorker.addPropertyChangeListener(new PropertyChangeListener() {
  @Override
  public void propertyChange(final PropertyChangeEvent event) {
    switch (event.getPropertyName()) {
    case "progress":
      myProgressBar.setIndeterminate(false);
      myProgressBar.setValue((Integer) event.getNewValue());
      break;
    }
 }
});
