            Do not load the images in the application loop. Loading an image is very time consuming because the image file has to be read and interpreted. Load the images once at the begin of the application:

            Your original problem is probably that the input values are not null, but rather empty strings.

            But conditional queries like this are a good use of the when() query builder method. If the first argument evaluates to a non-false value, the second argument is executed.

            Hide TextView when CollapsingToolbarLayout is Collapsed, and show it when expanded
            Asked 2021-May-29 at 20:11

            I am working on an app using a CollapsingToolbarLayout, with an ImageView inside it. I wanted to add a gradient on top of it to look nicer and to be able to read the CollapsingToolBar title better, so I made a little hack and added a Relative Layout with a textview inside it, then I added a background to that same TextView (which is the gradient I was talking about). The problem with this is that when the ToolBar is collapsed, the gradient still shows over it and I dont want it to happen, how can I make it invisible when the ToolBar is collapsed?

            Add an OnOffsetChangedListener to the AppBar and listen to the changes when it's collapsed or expanded and hide/show your TextView based on that.

            You need to draw the enemy (blob) on the screen instead of the map (display) Surface

            blob.draw(display)

            Javascript conflict: Div scrolling speed control & image shrink on scroll together
            Asked 2021-May-27 at 08:22

            I've been wrestling with this problem for a while without success, so I'm hoping someone with greater knowledge can offer a solution.

            By using a script to independently control the scroll speeds of specific divs, I've managed to create an effect along the lines of parallax scrolling: https://neilwhitedesign.co.uk/pt_testing_area/index(scrolling).html

            However, what I would also like to add, is a second script to reduce the size of the logo when the page is scrolls: https://neilwhitedesign.co.uk/pt_testing_area/index(headershrink).html

            Independently, these scripts are working exactly as I want them, but when I try to combine the two, there is a conflict and only the scrolling effect works.

            Looking at similar questions posted previously, one solution was to add a further script between the two, to call a noConflict. However, while adding this now makes the shrinking image effect work, it does so at the expense of the scrolling effect.

            • Is what I'm trying to achieve possible?
            • Is there a simple solution to get around the conflict?

            Please find my html and css below:

            It is because you declare window.onscroll twice and therefor it overwrites the first declaration. You just have to add the call of growShrinkLogo() to the second window.onscroll.

            Working example:
