Kotlin

patternLockView.setOnPatternListener(object : PatternLockView.OnPatternListener {
    override fun onStarted() {
        super.onStarted()
    }

    override fun onProgress(ids: ArrayList<Int>) {
        super.onProgress(ids)
    }

    override fun onComplete(ids: ArrayList<Int>): Boolean {
        /*
         * A return value required
         * if the pattern is not correct and you'd like change the pattern to error state, return false
         * otherwise return true
         */
        return isPatternCorrect()
    }
