Set image height as software matching

Question

I need to set the height of the imageview as matchparent programmatically. If it's a fixed height, I know how to set it.

but how can I set it as matchparent?

EDIT:

Actually the height of the parent layout is dynamic.so I need to make the height of the image as the height of the parent.

Answer 1

initiate LayoutParams.

assign the parent width and height and pass it to the setLayoutParams method of the image

Answer 2

imageView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT)); 

Answer 3

 imageView.getLayoutParams().height= ViewGroup.LayoutParams.MATCH_PARENT; 

Answer 4

 imageView.setLayoutParams (new ViewGroup.MarginLayoutParams (width, ViewGroup.LayoutParams.MATCH_PARENT)); 

The type of layout options depends on the parent view group. If you make a mistake, this will throw an exception.

Answer 5

You can use the MATCH_PARENT constant or its numerical value -1. A.

Answer 6

You can try this incase, which you would like to map to the parent. Sizing - width and height in

 web = new WebView(this); web.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
