LockPattern

Description

Imitate Alipay gesture password

仿支付宝手势密码解锁

Starting

创建手势密码可以查看 CreateGestureActivity.java 文件.
登陆验证手势密码可以看 GestureLoginActivity.java 文件.

Features

• 使用了 JakeWharton/butterknife butterknife

• 使用了 ACache 来存储手势密码

/**
 * 保存手势密码
 */
private void saveChosenPattern(List<LockPatternView.Cell> cells) {
    byte[] bytes = LockPatternUtil.patternToHash(cells);
    aCache.put(Constant.GESTURE_PASSWORD, bytes);
}

Warning: 使用 ACache 类保存密码并不是无限期的. 具体期限可以查看 ACache 类.

• 使用了 SHA 算法保存手势密码

/**
 * 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;
        }
    }
}

• 可以开启震动模式，当选中一个圈的时候，手机会震动

/**
 * 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;
}

• 可以开启绘制路径隐藏模式

/**
 * 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;
}
