How can i create Vertical arrangement?

i am trying to create a vertical arrangement but unable to create.
Hope anyone help me in Creating this extension.

My code

LinearLayout ll = new LinearLayout(context);
ll.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

My Imports

import android.view.ViewGroup.LayoutParams;
import android.widget.LinearLayout;

this code is not working for me .

sur @Mohamed_Tamer kindly have a look here

Note - please change my Topic category.

You need to add your linearLayout in a ViewGroup, you might use ViewGroup.add(view) method.

There isn’t a category for extension development in kodular community, you should ask in the app Inventor community:


please wait

the problem is that i am unable to create a Linear Layout

i already used this code

((ViewGroup) layout.getView()).addView(ll);

You didn’t show this code :slightly_smiling_face:

How? What happens when you use it.

take ______ = space

______LinearLayout ll = new LinearLayout(context);

Just removed the Space and it works fine

this solve my error . thanks for your time @Mohamed_Tamer

Seems that you was having a special character there, that the compiler failed to resolve it, which got removed when you removed the space :thinking:
