<com.itsxtt.patternlock.PatternLockView
    android:id="@+id/patternLockView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

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()
    }
})

Java

patternLockView.setOnPatternListener(new PatternLockView.OnPatternListener() {
    @Override
    public void onStarted() {

    }

    @Override
    public void onProgress(ArrayList<Integer> ids) {

    }

    @Override
    public boolean onComplete(ArrayList<Integer> ids) {
        /*

         * if the pattern is not correct and you'd like change the pattern to error state, return false
