The method inflate(int, ViewGroup, boolean) in the type LayoutInflater is not applicable for the arguments (int, int, boolean)

Question

I'm attempting to resolve a previous issue with setting fill parameters:

Thumbnail does not fill_parent as expected

however when I attempt to implement the fix provided in the answer I don't think I've implemented it correctly. When I attempt to do so I get an error regarding the inflation argument stating: The method inflate(int, ViewGroup, boolean) in the type LayoutInflater is not applicable for the arguments (int, int, boolean) however I'm not sure the exact parameter I should use to resolve this in order to get the ImageView to fill correctly.

JAVA:

@Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if(convertView == null){
            convertView = mInflater.inflate(R.layout.activity_main, R.layout.list_item_user_video, false);
        }
        UrlImageView thumb = (UrlImageView) convertView.findViewById(R.id.userVideoThumbImageView);

        TextView title = (TextView) convertView.findViewById(R.id.userVideoTitleTextView); 
        final Video video = videos.get(position);
        thumb.setImageDrawable(video.getThumbUrl());
        title.setText(video.getTitle());

        return convertView;
    }

ERROR:

The method inflate(int, ViewGroup, boolean) in the type LayoutInflater is not applicable for the arguments (int, int, boolean)

ERROR LOCATION:

convertView = mInflater.inflate(R.layout.activity_main, R.layout.list_item_user_video, false);

Answer 1

The second parameter to inflate() needs to be a ViewGroup . You are passing an int . Presumably, the second parameter should be parent .

Answer 2

You should put the parentview in the second argument of the methods signature - that is

 mInflater.inflate(R.layout.activity_main, parent, false);

where parent is the ViewGroup

Answer 3

As user2365568 points out, you should pass parent as the root parameter. The other answers indicate you should pass null or the convertView , which is wrong.
