View not filling screen

In the 'Opening a Webpage Within the App' part of the blog reader app, when dragging a webview onto the newly created activity (exactly into the top left pixel) . It does not fill the screen, even with fill width and fill height toggled. There is still a small grey margin (which does appear when running the app on my galaxy s3) I do hope I havn't just made some stupid mistake, any feedback would be much appreciated. Thanks =)

Hi, I haven't taken the course, but it sounds like you either have a margin set on the web view or some padding on it's parent view (Like a Linear layout). Make sure "android:layout_margin" isn't set on the webview and make sure "android:padding" isn't set on the parent view (if there is one!) Hope this helps!

It turns out there was padding on the parent view! Thankyou!

This didn't seem to happen on Ben's video, so i assume padding isn't automatically added on his automatically generated relative layouts, due to a different version i suppose? or am i missing something here? This was actually happening on my other views but i didn't really realise as the padding appears white and not grey on those views. The padding was put there automatically and is defined in the res directory under values > dimens.xml:

 <!-- Default screen margins, per the Android Design guidelines. -->
<dimen name="activity_horizontal_margin">16dp</dimen>
<dimen name="activity_vertical_margin">16dp</dimen>

Anyway thanks again =)

Hi Sam, sounds like you're catching the newer default padding. Check out this older forum post: https://teamtreehouse.com/forum/fullscreen

No worries! Our search functionality has been a little wonky since our redesign launched. I have had trouble finding things, too, and I know exactly what I'm looking for! :)
