which is an ArrayList inside this class TvShowEpisodeLoader
I also have another class named TvShowEpisodeDetailsFragment
I want to access mEpisodeList
from TvShowEpisodeDetailsFragment
I want to get mEpisode

QUESTION
I have a view hierarchy as shown in the image below.
I'm getting strange scroll behaviors like,
- If I scroll (drag slowly or fling) from Area 1 the
AppBar
collapses along with it. This is fine. - But if I drag slowly from Area 2 the
AppBar
does not collapse. It stays there andRecyclerView
goes beneath it. However, it works fine with a fling.

QUESTION
I am using the splitting.js javascript library in my Rails 6 project. When I try to load the page I get "Uncaught TypeError: Splitting is not a function" in the console.
I have installed the javascript library using Yarn:
yarn add splitting
Splitting()
is called with other Javascript in scripts.js which is required in my applicaiton.js file. I have configured my application.js file in a number of ways to try to fix the issue but to no avail. Here is my current iteration of this file (entire file included in case there are other interactions to consider):
ANSWER
Answered 2021-Jun-04 at 10:25I solved this problem thanks to some help from @rossta. I needed to move all my import statement for the splitting.js module from application.js to the script.js file in which the module was being called. So I added the following to the top of scripts.js:
QUESTION
i'm kind of new to laravel first time developing on it. My goal is to get some filtered events to show, the filters should all work together ('filter 1' AND 'filter2' ecc..) even when some are empty. The problem that i'm getting is that when my filter fields are empty the query won't return any event. My CONTROLLER code:
...ANSWER
Answered 2021-Jun-01 at 00:50Your 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.
QUESTION
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?

Answered 2021-May-29 at 20:11Add an OnOffsetChangedListener
to the AppBar

QUESTION
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:
HTML
...ANSWER
Answered 2021-May-27 at 08:22It 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
.

I am relatively new to Ajax. I've created two
elements inside of them, both of them lead to other HTML files. What I am trying to achieve is that whenever I click on one of the links, the page automatically loads the HTML file related to it, however its not working for me. Whenever I click on one of the links, nothing happens. Thanks in advance! I am using JQuery with Ajax.
FIRST HTML FILE
...ANSWER
Answered 2021-Apr-27 at 14:24First of, you should use a templating engine (i.e: PHP) since it makes it infinitely easier to just change a head tag in one place than in N files. Same goes for scripts in footer etc.
Every page should be accessible on its own (via URL) but give the feel of no tab refresh, here's where AJAX comes at play:
