StackTrace

I'm making a recipe search application using forkify API. I get such json (let's take pizza recipes for example). I've made a recycler and searchable, but the recipes themselves are given as a link to the site with that recipe (see source_url in the json). I've made a webview for this, but there's one problem. I need to get that source_url and have it match the recipe I clicked on. I tried to make an additional element in resycler, small invisible textview, and put source_url there, so when I clicked on it, it would take text and pass it to a variable and load it as url into webview. (Very silly solution, but I didn't think of another one.) It's not what I had in mind. Basically my code works, but the url is not passed from all textViews. I've been observing its behaviour and I can only assume that it loads every 4 in vertical mode and every 2 in horizontal mode. And this is not what I need. Please help me to solve this problem. Below is my code:

How can I achieve this?

Right now I have applied a stroke color to one card view

Just as a note further, I want to get the selected CardView id or the amount when the donate button is clicked and pass the card view (amount) to the payment gateway.

This is what it looks like:

donate_fragment.xml // only the card view section and the button

I would like to create a Custom CardView where I can add additional child components when I create an instance as follows :

I am making a simple recipe search app using recipe search API but the problem is the app fetches all the data from API but my app displays only one in recycler view then what should I do? Please help

MainActivity.kt

When I click the cardView with the id addNotice in the activity_main.xml the second Activity UploadNotice is supposed to show up, but my Android studio app closes and the second Activity that I've created never shows up. I'm new to Android Studio and Java so I would appreciate it a lot if anyone can help me!

Here is my MainActivity.java :

As you can see, the images don't seem to be aligning with each other very well. It seems to happen when the text for "Hobby" grows longer than the ones next to it. I still can't seem to fix this though. Here's the xml for the horizontal view:
