本篇文章為大家展示了Android識(shí)別NFC芯片制造商的方法是什么,內(nèi)容簡(jiǎn)明扼要并且容易理解,絕對(duì)能使你眼前一亮,通過(guò)這篇文章的詳細(xì)介紹希望你能有所收獲。
通過(guò)NFC模塊的Serial Number即UID,用戶訪問(wèn)權(quán)限為R只讀,每顆NFC芯片獨(dú)有序列號(hào)(UID),在出廠時(shí)寫入,用戶不能改寫。
通過(guò)Intent獲取UID
/** * 讀取nfcUID 返回String類型大寫的UID * * 這個(gè)測(cè)試順便加上的,下面用不到,做個(gè)筆記~~ * */ public static String readUID(Intent intent) throws UnsupportedEncodingException { Tag tagFromIntent = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG); byte[] uid = tagFromIntent != null ? tagFromIntent.getId() : null; return HexUtil.encodeHexStr(uid, false); } /** * 讀取nfcUID 返回byte[]數(shù)組 * */ public static byte[] readUID(Intent intent) throws UnsupportedEncodingException { Tag tagFromIntent = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG); return tagFromIntent.getId(); }
HexUtil工具類:
public class HexUtil { /** * 用于建立十六進(jìn)制字符的輸出的小寫字符數(shù)組 */ private static final char[] DIGITS_LOWER = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'}; /** * 用于建立十六進(jìn)制字符的輸出的大寫字符數(shù)組 */ private static final char[] DIGITS_UPPER = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'}; /** * 將字節(jié)數(shù)組轉(zhuǎn)換為十六進(jìn)制字符數(shù)組 * * @param data byte[] * @param toDigits 用于控制輸出的char[] * @return 十六進(jìn)制char[] */ protected static char[] encodeHex(byte[] data, char[] toDigits) { int l = data.length; char[] out = new char[l << 1]; // two characters form the hex value. for (int i = 0, j = 0; i < l; i++) { out[j++] = toDigits[(0xF0 & data[i]) >>> 4]; out[j++] = toDigits[0x0F & data[i]]; } return out; } /** * 將字節(jié)數(shù)組轉(zhuǎn)換為十六進(jìn)制字符串 * * @param data byte[] * @param toLowerCase <code>true</code> 傳換成小寫格式 , <code>false</code> 傳換成大寫格式 * @return 十六進(jìn)制String */ public static String encodeHexStr(byte[] data, boolean toLowerCase) { return encodeHexStr(data, toLowerCase ? DIGITS_LOWER : DIGITS_UPPER); } /** * 將字節(jié)數(shù)組轉(zhuǎn)換為十六進(jìn)制字符串 * * @param data byte[] * @param toDigits 用于控制輸出的char[] * @return 十六進(jìn)制String */ protected static String encodeHexStr(byte[] data, char[] toDigits) { if (data == null) { return ""; } return new String(encodeHex(data, toDigits)); } }
通過(guò)UID去查詢廠商
