友我科技IC卡读卡器Android开发应用实例

此实例将采用线程自动读取IC卡的卡号，并将卡号输出到指定位置。

代码如下:

public class AutoReadCard extends Activity { private TextView tv;
private int offset;
private boolean bStop;
@Override
protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
setContentView(R.layout.activity_autoreadcard);
bStop =false; tv = (TextView) findViewById(R.id.txtcard);
tv.setMovementMethod(ScrollingMovementMethod.getInstance());

Thread thread=new Thread(new Runnable()
{
byte[] CardNo;
@Override
public void run()
{
while(!bStop)
{

try {
Thread.sleep(100);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if( MainActivity.rfidreader.ISO14443A.YW_RequestCard(MainActivity.rfidreader.ISO14443A.REQUESTMODE_ACTIVE)<0)continue; CardNo=MainActivity.rfidreader.ISO14443A.YW_AntiCollideAndSelect(MainActivity.rfidreader.ISO14443A.MULTIMODE_ONE);

if(CardNo==null)continue;

runOnUiThread(new Runnable()
{
@Override
public void run()
{
tv.append(MainActivity.bytesToHexString(CardNo) + "\n");
offset=tv.getLineCount()*tv.getLineHeight();
if(offset>tv.getHeight())tv.scrollTo(0,offset-tv.getHeight());
}
}); MainActivity.rfidreader.ISO14443A.YW_CardHalt();
MainActivity.rfidreader.ReaderHardware.YW_Buzzer(5, 5, 1);
}

}
});
thread.start();

}

@Override
protected void onDestroy() {
bStop=true;
super.onDestroy();
};
}
