如何为ViewGroup设置高度

Question

Can you please tell me how can I setHeight for a ViewGroup? I see there is a layout(l,t,r,b);

But that is different form setHeight(), since I don't know where should be the top/bottom of the viewGroup. I need to set the height of the ViewGroup and return that to ListAdapter.

Thank you.

You can try using setLayoutParams()

myViewGroup.setLayoutParams(new LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT));

See here the descriptions of the parameters to LayoutParams

public ViewGroup.LayoutParams (int width, int height)    

Creates a new set of layout parameters with the specified width and height.

width the width, either MATCH_PARENT, WRAP_CONTENT or a fixed size in pixels
height the height, either MATCH_PARENT, WRAP_CONTENT or a fixed size in pixels
