下面是步驟：
1.獲取管理權限：這個開發包里已經集成了，只需要調用一句代碼就可以搞定，這個還是挺方便的。
PermissionUtil.grantNeedPermission(this);
2.打開NFC，並監聽NFC事件，這段如果不懂，直接在網上搜安卓使用NFC就可以看到介紹
private NfcAdapter mAdapter = null; // 定義NFC適配器
mAdapter = NfcAdapter.getDefaultAdapter(getApplicationContext());
pi = PendingIntent.getActivity(this, 0, new Intent(this, getClass())
.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP), 0);
tagDetected = new IntentFilter(NfcAdapter.ACTION_TECH_DISCOVERED);//.ACTION_TAG_DISCOVERED);
tagDetected.addCategory(Intent.CATEGORY_DEFAULT);
mTechLists = new String[][]{new String[]{NfcB.class.getName()}, new String[]{NfcA.class.getName()}};
if (mAdapter != null && !mAdapter.isEnabled()) {
Toast.makeText(this, "NFC尚未開啟", Toast.LENGTH_SHORT).show();
}
3.因為我的NFC事件是在子線程中的，所以new了一個handle
private static class MyHandler extends Handler {
private final WeakReference<IDCardScannerActivity> mActivity;
public MyHandler(IDCardScannerActivity activity) {
mActivity = new WeakReference<IDCardScannerActivity>(activity);
}
@Override
public void handleMessage(Message msg) {
System.out.println(msg);
if (mActivity.get() == null) {
return;
}
if (msg.what == 1002)
throw new RuntimeException();
else {
try {
mActivity.get().todo(msg);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
}
4.初始化類：
private OTGReadCardAPI ReadCardAPI; // 定義讀取類
ReadCardAPI = new OTGReadCardAPI(getApplicationContext(), this, false); // 初始化類，第三個是回調地址，第三個直接傳false就可以了
// 設置服務器地址及端口
ArrayList<Serverinfo> twoCardServerlist = new ArrayList<Serverinfo>();
twoCardServerlist.add(new Serverinfo("id.yzfuture.cn", 8848));
ReadCardAPI.setServerInfo(twoCardServerlist, null, bTestServer);
5.當手機檢測到芯片靠近的時候，會回調onNewIntent，在這個里面直接 讀取即可。但是為避免出現問題，我直接發送消息到 Handle里面處理。
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
inintent = intent;
mHandler.sendEmptyMessageDelayed(1, 0);
}
6.在MyHandler 中會調到todo里面，這里面是具體的操作
public void todo(Message msg) throws FileNotFoundException {
int tt = 0;
m_szProcess = "";
process.setText("");
m_szAppKey = sharedPreferences.getString("AppKey", "");
int nnum = ReadCardAPI.GetAppKeyUseNum(m_szAppKey);
if (nnum <= 0) nnum = 0;
numtxt.setText(String.valueOf(nnum));
if (m_szAppKey.isEmpty() || nnum<=0)
{
regeditAppkey(true);
}
appkeyTxt.setText(m_szAppKey);
if (!m_szAppKey.isEmpty() && nnum>0)
{
if (msg.what == 1 || msg.what==1005)
{
if (msg.what == 1005)
{
inintent = null;
}
tt = ReadCardAPI.NfcReadCard(m_szAppKey, null, inintent, eCardType.eTwoGeneralCard, "", m_bAuthon);
}
if (m_bshow)
{
userInfo.setText(m_szUserInfo);
}
if (tt == 41)
{
if (m_berror)
{
setdialog("讀卡失敗！" + ReadCardAPI.GetErrorInfo());
}
else
{
int nerr = ReadCardAPI.GetErrorCode();
if (nerr==-24997)
{
setdialog("此設備沒有解碼權限！");
}
else setdialog("讀卡失敗！");
}
edtype.setText("");
edname.setText("");
edenname.setText("");
edid.setText("");
addTrue.setText("");
sexTrue.setText("");
mzTrue.setText("");
jgTrue.setText("");
birthTrue.setText("");
yxqTrue.setText("");
gjTrue.setText("");
process.setText("");
}
if (tt == 90)
{
if (ReadCardAPI.GetTwoCardInfo().arrTwoIdPhoto != null) {
idimg.setBackground(new BitmapDrawable(Bytes2Bimap(ReadCardAPI.GetTwoCardInfo().arrTwoIdPhoto)));
}
if (ReadCardAPI.GetTwoCardInfo().szTwoType.equals("J")) {
edtype.setText("港澳居民居住證");
othernoTrue.setText(ReadCardAPI.GetTwoCardInfo().szTwoOtherNO);
signTrue.setText(ReadCardAPI.GetTwoCardInfo().szTwoSignNum);
} else {
edtype.setText("居民二代證");
othernoTrue.setText("");
signTrue.setText("");
}
edid.setText(ReadCardAPI.GetTwoCardInfo().szTwoIdNo.trim());
edname.setText(ReadCardAPI.GetTwoCardInfo().szTwoIdName.trim());
addTrue.setText(ReadCardAPI.GetTwoCardInfo().szTwoIdAddress.trim());
sexTrue.setText(ReadCardAPI.GetTwoCardInfo().szTwoIdSex.trim());
mzTrue.setText(ReadCardAPI.GetTwoCardInfo().szTwoIdNation.trim() + "族");
gjTrue.setText("中國");
jgTrue.setText(ReadCardAPI.GetTwoCardInfo().szTwoIdSignedDepartment.trim());
birthTrue.setText(ReadCardAPI.GetTwoCardInfo().szTwoIdBirthday.substring(0, 4) + "-" + ReadCardAPI.GetTwoCardInfo().szTwoIdBirthday.substring(4, 6) + "-" + ReadCardAPI.GetTwoCardInfo().szTwoIdBirthday.substring(6, 8));
String startDate = ReadCardAPI.GetTwoCardInfo().szTwoIdValidityPeriodBegin.substring(0, 4) + "-" + ReadCardAPI.GetTwoCardInfo().szTwoIdValidityPeriodBegin.substring(4, 6) + "-" + ReadCardAPI.GetTwoCardInfo().szTwoIdValidityPeriodBegin.substring(6, 8);
String endDate = "";
int nlen = ReadCardAPI.GetTwoCardInfo().szTwoIdValidityPeriodEnd.indexOf("長期");
if (nlen != -1) {
endDate = "長期";
} else {
endDate = ReadCardAPI.GetTwoCardInfo().szTwoIdValidityPeriodEnd.substring(0, 4) + "-" + ReadCardAPI.GetTwoCardInfo().szTwoIdValidityPeriodEnd.substring(4, 6) + "-" + ReadCardAPI.GetTwoCardInfo().szTwoIdValidityPeriodEnd.substring(6, 8);
}
yxqTrue.setText(startDate + "~" + endDate);
//process.setText("100");
ReadCardAPI.release();
}
}
}
到此就讀取完了。
