FloatingAction menu button On click option is not working in android

Question

Here is the xml file for the menu button:

<?xml version="1.0" encoding="utf-8"?>

Add to the XML Layout:

<android.support.design.widget.FloatingActionButton
        android:id="@+id/myFAB"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/your_icon"
        app:elevation="4dp"
        ... />

Add to the code behind:

FloatingActionButton myFab = (FloatingActionButton) myView.findViewById(R.id.myFAB); 
myFab.setOnClickListener(new View.OnClickListener() { 
    public void onClick(View v) { 
          // TODO something when floating action menu third item clicked
    } 
});
