How do you set height of any component in building extension?

[oseamiya]

Go to top of the docs and see whether it is for View or ListView ...

See my code

@Faraz_Firoz

ListView listView = new ListView(this.container.$context());

View v = (listView);

In view I set listview to get view

[oseamiya]

@Faraz_Firoz

View v = (listView);

still v is View ...
You'venot set v as listView anywhere

@Faraz_Firoz

See my code

That's why i am saying

[oseamiya]

@Faraz_Firoz

View v = (listView);

ListView v = (ListView) listView;

When I set public ListView listView;
and listView.setDivider(new ColorDrawable(Color.parseColor(color)));
It works thank you all of you
