Android仿支付寶手勢密碼解鎖功能_Android

Starting

建立手勢密碼可以查看 CreateGestureActivity.java 檔案.

登陸驗證手勢密碼可以看 GestureLoginActivity.java 檔案.

Features

使用了 JakeWharton/butterknife butterknife

使用了 ACache 來儲存手勢密碼

/**  * 儲存手勢密碼  */ private void saveChosenPattern(List<LockPatternView.Cell> cells) {  byte[] bytes = LockPatternUtil.patternToHash(cells); aCache.put(Constant.GESTURE_PASSWORD, bytes);}

Warning: 使用 ACache 類儲存密碼並不是無限期的. 具體期限可以查看 ACache 類.

使用了 SHA 演算法儲存手勢密碼

/**  * Generate an SHA-1 hash for the pattern. * Not the most secure, but it is at  * least a second level of protection. First level is that the file is in a  * location only readable by the system process.* * @param pattern  * @return the hash of the pattern in a byte array.  */public static byte[] patternToHash(List<LockPatternView.Cell> pattern) {   if (pattern == null) {     return null;  } else {    int size = pattern.size();     byte[] res = new byte[size];    for (int i = 0; i < size; i++) {      LockPatternView.Cell cell = pattern.get(i);    res[i] = (byte) cell.getIndex();   }     MessageDigest md = null;   try {    md = MessageDigest.getInstance("SHA-1");       return md.digest(res);    } catch (NoSuchAlgorithmException e) {    e.printStackTrace();       return res;   }  } }

可以開啟震動模式，當選中一個圈的時候，手機會震動

/** * Set whether the view will use tactile feedback.  *If true, there will be  * tactile feedback as the user enters the pattern.  * @param tactileFeedbackEnabled Whether tactile feedback is enabled  */ public void setTactileFeedbackEnabled(boolean tactileFeedbackEnabled) { mEnableHapticFeedback = tactileFeedbackEnabled;}

可以開啟繪製路徑隱形模式

/**  * Set whether the view is in stealth mode. If true, there will be no  * visible feedback as the user enters the pattern.  * @param inStealthMode Whether in stealth mode.  */public void setInStealthMode(boolean inStealthMode) { mInStealthMode = inStealthMode;}
