Pls help

I think your issue is that you specify the width of the view to be MATCH_PARENT, but the horizontal/vertical arrangements will WRAP_CONTENT, so you have this juxtaposition where the parent wants to be as small as the children, and the children want to be as big as the parent. What happens if you set your LayoutParams to be WRAP_CONTENT on both dimensions?

same issue sir

[nandu aeer]

public void label(HVArrangement paramHVArrangement, String paramString1, int paramInt1)
{
ViewGroup layout = (ViewGroup)paramHVArrangement.getView();
TextView tv = new TextView(context);
tv.setText(paramString1);
tv.setId(paramInt1);
tv.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
layout.addView(tv,paramInt1);


}
}

[nandu aeer]

when i set wrap content for both diemension same error

It might be worthwhile getting this first working in a simple project in Android Studio to understand how it works using the debugging facilities there. Once you know it works using the LinearLayout in Android Studio, you can backport the behavior to your App Inventor extension to determine whether or not it's an issue with how we handle LinearLayouts.
