Dividers | simple Android library to create easy separators | RecyclerView library

You can try to change your method like in the following snippet: (you can disable items or you can remove them)

(B ∧ D) ∨ (A ∧ D) is the correct "sum of products" expression for this Karnaugh map, and (A ∨ B) ∧ D is an equivalent expression (per the "OR distributive law"), but it is no longer in a "sum of products" form.

You did (instead of using the "OR distributive law"): instead of noting (from the top of the Karnaugh map) that the B value does not change for the first 2x2 block and that the A value does not change for the second 2x2 block, you noted further that these two columns of size 2 overlap forming three columns defined by (A ∨ B).

That is fine, but it does not give the "sum of products" (groups of AND'd variables OR'd together), which is what the 2^n rule relates to. Instead you by happenstance ended up with the actual "product of sums" (groups of OR'd variables AND'd together).

The "formal", "graphical", "traditional", "easy", etc. way (which also has a 2^n rule, but for 0s instead of 1s) of getting to your final result is to instead of 1s, circle the 0s, noting again what variable values on the top and/or on the right side do not change, but this time not these values. In your example, the four 0s at the top and the four 0s at the bottom result in the D "sum" (note this "circle" spans from the top to the bottom forming a "logical" circle so-to-speak). The remaining two 0s are combined with the 0 above them and the 0 below them, resulting in the (A ∨ B) "sum" (the idea is to cover all 0s while also selecting the biggest 2^n blocks even if they overlap). (A ∨ B) ∧ D is the "product" of these two "sums". Check out: Minterm vs Maxterm Solution.

The method is "perfect" (as long as the "circles" are as big as possible and nothing is missed). If the "circles" are not as big as possible (but nothing is missed), the result will still be logically correct, but it will use more gates than the minimum.

You could place your horizontal line before the multicols:

Try this method:

Answering your questions:

The docs also say:

This constructor is appropriate for list views with a large number of item and separator children because the builders are only called for the children that are actually visible.

So, according to the page you read and the page I quoted here, in both, the builder is called only once for each item in the list. No matter the size of the list. It only mentions, the list should be of fixed size, not small size. It's due to a range exception that could occur.

As stated before, the performance isn't much different, since the builder is called the same amount of time.

There is no need to, since ListView.separated is perfect for your case.

I tried to find a most general solution to this problem, as I thought you may want to add more paned windows to main_panel. Anyway this can be achieved with fewer lines of code, but for demonstration I did it more steps than needed.

You can just divide the clk by 250 to get a 400kHz clk. Something along the lines of:

To fix this you should add the android:textDirection="ltr" which defines the direction of the text from Left to Right. The android:layoutDirection="rtl" defines the direction of layout drawing so it will draw the radio button to the right side of text.

Your layout should be like the below:

i was able to finally resolve it :)

so in the main style.scss file I added:
