Multiautocompletetextview Update ArrayAdapter List By Previous Word

Question

Frist In AutoComplete ArrayAdapter Show item like Action , Car, Bike, Ships, helicopter etc

When user Write Action. then show Action[] Array in AutoComplte in ArrayAdapter like Start, terminate,etc

When user write Car. then show Car[] String Array in AutoComplete ArrayAdapter Like Modified, import , etc

More like this In MultiAutoCompleteTextView Android Java

I write Code For More detail `

public SmEditor editor;
String[] Class = new String[] { "Action", "Car", "Bike", "Helicopter"};

String[] Action = new String[] {"Start()","Terminate()","isVailid()"};
String[] Car = new String[] {"OpenDoor()","Modified()","TurnOn()"};
String[] Helicopter = new String[] {"StartFan()","Fly()","Pailot()"};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    editor = findViewById(R.id.editor);
      editor.setAdapter(this,android.R.layout.simple_list_item_1 ,Class);
}

}`

What To Do For That

I need To Update ArrayList When User Write Word before "."

Class.ClassString()

I hope you understand what i say
