以下是一个使用APDU命令从NFC卡读取Track1/Track2数据的示例代码：

import android.nfc.tech.IsoDep;

public class NFCReader {
    private static final String SELECT_APDU_HEADER = "00A40400";
    private static final byte[] SELECT_AID_COMMAND = {
            (byte) 0xA0, 0x00, 0x00, 0x00, 0x03, 0x10, 0x10
    };
    private static final byte[] READ_TRACK1_COMMAND = {
            (byte) 0x00, (byte) 0xB2, 0x01, (byte) 0xC5, 0x00
    };
    private static final byte[] READ_TRACK2_COMMAND = {
            (byte) 0x00, (byte) 0xB2, 0x02, (byte) 0xC5, 0x00
    };

    public static String readTrackData(IsoDep isoDep) {
        try {
            isoDep.connect();
            byte[] command = buildSelectApdu(SELECT_AID_COMMAND);
            byte[] result = isoDep.transceive(command);
            if (result != null && result.length >= 2) {
                int status = ((result[result.length - 2] & 0xFF) << 8)
                        | (result[result.length - 1] & 0xFF);
                if (status == 0x9000) {
                    byte[] track1Result = isoDep.transceive(READ_TRACK1_COMMAND);
                    byte[] track2Result = isoDep.transceive(READ_TRACK2_COMMAND);
                    if (track1Result != null && track1Result.length >= 2
                            && track2Result != null && track2Result.length >= 2) {
                        status = ((track1Result[track1Result.length - 2] & 0xFF) << 8)
                                | (track1Result[track1Result.length - 1] & 0xFF);
                        if (status == 0x9000) {
                            String track1Data = new String(track1Result, 0, track1Result.length - 2);
                            String track2Data = new String(track2Result, 0, track2Result.length - 2);
                            return "Track 1 Data: " + track1Data + "\nTrack 2 Data: " + track2Data;
                        }
                    }
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                isoDep.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        return null;
    }

    private static byte[] buildSelectApdu(byte[] aid) {
        byte[] apdu = new byte[SELECT_APDU_HEADER.length() / 2 + 1 + aid.length];
        int offset = 0;
        System.arraycopy(hexStringToByteArray(SELECT_APDU_HEADER), 0, apdu, offset, SELECT_APDU_HEADER.length() / 2);
        offset += SELECT_APDU_HEADER.length() / 2;
        apdu[offset++] = (byte) aid.length;
        System.arraycopy(aid, 0, apdu, offset, aid.length);
        return apdu;
    }

    private static byte[] hexStringToByteArray(String s) {
        int len = s.length();
        byte[] data = new byte[len / 2];
        for (int i = 0; i < len; i += 2) {
            data[i / 2] = (byte) ((Character.digit(s.charAt(i), 16) << 4)
                    + Character.digit(s.charAt(i + 1), 16));

请注意，此示例代码假定您已经获取了NFC卡的权限，并且已经在onNewIntent()方法中处理了NFC意图。您需要将上述代码放入适当的位置，并在您的应用程序中进行适当的调用。

此代码使用IsoDep类来与NFC卡进行通信，使用APDU命令选择应用程序，然后读取Track1和Track2数据。将此代码与您的应用程序的逻辑结合使用，以根据您的需求进行适当的处理和显示读取的数据。
