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写二代身份证的卡号。

代码如下:

public class ID2Card extends Activity {
private TextView tv;
private int offset;
@Override
protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
setContentView(R.layout.activity_id2card);
tv = (TextView) findViewById(R.id.txtIDcardUID);
tv.setMovementMethod(ScrollingMovementMethod.getInstance());

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


byte[] CardNo=MainActivity.rfidreader.ID2Card.YW_ChinaIDV2_RequestCardNo();

if(CardNo==null)return;
tv.append(MainActivity.bytesToHexString(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);
}
});


}
}
