友我科技IC卡读卡器Android开发应用实例

此实例将手动点击按钮读取IC卡的卡号，并将卡号输出到指定位置。

代码如下:

public class ReadCard extends Activity {
private RadioButton rd;
private TextView tv;
private int offset;
@Override
protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
setContentView(R.layout.activity_readercard);

rd=(RadioButton) findViewById(R.id.rbhex);
tv = (TextView) findViewById(R.id.txtcard);
tv.setMovementMethod(ScrollingMovementMethod.getInstance());

Button button = (Button) findViewById(R.id.btnreadCardNo);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {

if( MainActivity.rfidreader.ISO14443A.YW_RequestCard(MainActivity.rfidreader.ISO14443A.REQUESTMODE_ALL)<0)return; byte[] CardNo=MainActivity.rfidreader.ISO14443A.YW_AntiCollideAndSelect(MainActivity.rfidreader.ISO14443A.MULTIMODE_ONE);

if(CardNo==null)return;
if(rd.isChecked())
{
tv.append(MainActivity.bytesToHexString(CardNo) + "\n");
}
else
{
tv.append(MainActivity.Get10DecFromCardNo(CardNo) + "\n");
}
offset=tv.getLineCount()*tv.getLineHeight();
if(offset>tv.getHeight())tv.scrollTo(0,offset-tv.getHeight());
MainActivity.rfidreader.ReaderHardware.YW_Buzzer(5, 5, 1);
}
});


}
