该单元附有一个稀缺的文档,SDK中的演示应用程序实现了固件更新和几个对话框,这些实际上是如何实现基本功能(添加到代码中的几个而不是很好的注释).
我已经在基本的活动中实现了接口,并且试图检测该单元何时连接或断开连接,但是似乎监听器将两个事件(连接/断开连接)捕获为“断开连接”,更不用说尝试读取卡.
有没有人在AndroID上使用这个单位,并有一些明确的例子？
顺便说一句,这是我的课：

解决方法 这是我与UniMag一起使用的.使用处理程序输出刷新的数据,并使用“滑动”按钮开始滑动.要改善,请等待读卡器报告已连接/准备滑动,然后启用按钮,等待滑动时禁用,并在接收数据后重新启用.import java.util.regex.Matcher;import java.util.regex.Pattern;import IDTech.MSR.XMLManager.StructConfigParameters;import IDTech.MSR.uniMag.uniMagReader;import IDTech.MSR.uniMag.uniMagReaderMsg;import androID.app.Activity;import androID.os.Bundle;import androID.os.Handler;import androID.os.Message;import androID.util.Log;import androID.vIEw.VIEw;import androID.vIEw.VIEw.OnClickListener;import androID.Widget.button;import androID.Widget.TextVIEw;public class MainActivity extends Activity implements uniMagReaderMsg { private uniMagReader myUniMagReader = null; private button btnSwipe; @OverrIDe public voID onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentVIEw(R.layout.activity_main); if(myUniMagReader == null) { myUniMagReader = new uniMagReader(this,this); myUniMagReader.setSaveLogEnable(false); myUniMagReader.setXMLfilenameWithPath(null); myUniMagReader.loadingConfigurationXMLfile(true); //myUniMagReader.setVerboseLoggingEnable(true); myUniMagReader.registerListen(); } btnSwipe = (button) findVIEwByID(R.ID.button1); btnSwipe.setonClickListener(new OnClickListener() { @OverrIDe public voID onClick(VIEw v) { myUniMagReader.startSwipeCard(); } }); } @OverrIDe public voID onDestroy() { myUniMagReader.stopSwipeCard(); myUniMagReader.unregisterListen(); myUniMagReader.release(); super.onDestroy(); } @OverrIDe public boolean getUserGrant(int arg0,String arg1) { Log.d("UniMag","getUserGrant -- " + arg1); return true; } @OverrIDe public voID onReceiveMsgautoConfigProgress(int arg0) { // Todo auto-generated method stub Log.d("UniMag","onReceiveMsgautoConfigProgress"); } @OverrIDe public voID onReceiveMsgCardData(byte arg0,byte[] arg1) { Log.d("UniMag","onReceiveMsgCardData"); Log.d("UniMag","Successful swipe!"); String strData = new String(arg1); Log.d("UniMag","SWIPE - " + strData); if(myUniMagReader.isSwipeCardRunning()) { myUniMagReader.stopSwipeCard(); } // Match the data we want.
