Phidg​​et RFID 未连接（ANDROID 和 PHIDGET）

Question

我目前在 Eclipse 中遇到问题，即使我的 Phidg​​et RFID 连接了设备（模拟器）没有连接，我已经在与 Android 无关的普通 Java 类中运行它并且它可以工作。我已经重启过很多次了。

下面是 log cat 报告：

下面是我的代码：

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import com.phidgets.InterfaceKitPhidget;
import com.phidgets.Phidget;
import com.phidgets.PhidgetException;
import com.phidgets.RFIDPhidget;
import com.phidgets.event.TagGainEvent;
import com.phidgets.event.TagGainListener;


public class AddFood  extends Activity {
        /** Called when the activity is first created. */
    RFIDPhidget rfid;

    static String x ="NULL";
    int i = 0;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.addfood);
        final TextView mytext=(TextView)findViewById(R.id.widget96);


try
{

        com.phidgets.usb.Manager.Initialize(this);
        rfid = new RFIDPhidget();
        rfid.setAntennaOn(true);
        rfid.setLEDOn(true);

        //Begin the TagGained event, allowing for users to read the RFID values



        rfid.addTagGainListener(new TagGainListener()
        {

            public void tagGained(TagGainEvent oe)
            {


                Object y = (oe.getValue());
                x= y.toString();
            }
        });
        rfid.open(34235);


        long StartTime,RunTime;
        StartTime=System.currentTimeMillis();
        do{

            RunTime=System.currentTimeMillis();
            if (x.equals("NULL")) {

                //Continue waiting for input
                }
            else

            StartTime = 10000; //Overload the result so the loop ends
        }
        while (RunTime-StartTime<5000);

        rfid.close();
        com.phidgets.usb.
        Manager.Uninitialize();

}
catch(PhidgetException e)
{

    e.printStackTrace();
}

        Button mybutton = (Button) findViewById(R.id.Button1);
        mybutton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {






        }


        });

}

}

和我的 Android 清单：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="myFood.myFood"
      android:versionCode="1"

</manifest> 

如果任何人有 PHIDGETS 或类似内容的经验，我们将不胜感激。

Answer 1

使用 Phidg​​et WebService，我将 open() 更改为 open(IP,PORT)。效果很好。

Answer 2

尝试使用 rfid.openAny();
并在 phidget 插入的机器上插入 ip 地址，

例如 rfid.openAny("192.168.10.1", 34325);
这样您的 Android 设备就可以通过网络读取数据并与之交互
