Overdraw | audio plug-in that implements a waveshaper

I'm trying to build a gameengine in SDL2 with cpp. I have a class called 'entity' which has some data for movement and also some pointers to a surface and a texture. A function "render" is called inmass to render each sprite based on the g_entities vector.

Suppose i have a file in res/layout

I wrote a function that "draws" a circle into a coordinate system (a 2d array/list):

I have a class named DrawView which extends View and is on top of a TableLayout. I'm using this class to draw 1 simple line using the drawLine() method. My TableLayout is being overdrawn because my DrawView class is on top of it. How can I prevent this? My line needs to be on top of the TableLayout, said line isn't using the whole canvas, so I thought setting the background to transparent would fix it, which isn't the case.

I am trying to draw some lines and rectangles on an existing window. I found the following code to draw on the desktop that works perfectly fine.

Or kind of.

I've got an activity with a fragment container. Each Fragments layout has no background itself. I've already tried to set background to transparent - no effect. Also I'm using FragNav library to handle fragment transactions.

The thing is - widnows background shows correctly in the editor xml preview.

Style:

I have a list of numbers and from this list, I want to create 3 more lists that contain the maximum, average, and 5th largest number from it. My original list overdraw is the block of lists, which means it has sub-blocks in it and each block has 6 numbers in it and there are a total of 3 blocks or 6x3 matrix or array.

I hope that someone can point me in the right direction, as I am new to programming.

I made a basic banking application. It displays a balance for the account, has a textbox for the user to enter the amount, and 2 buttons: one for depositing an amount into the account and one for withdrawing an amount. If the user tries to deposit or withdraw a negative number or "0" then it gives an error that it isn't a valid amount. If the user tries to withdraw more than is in the account, it gives an error that they cannot withdraw more money than is in the account.

My problem is that all the error messages are working for the deposit button, but not for the withdraw button. I used nested If structure, output to a label at the bottom.

I tried using breakpoints to examine my variables, but didn't find any issues.

I don't really want the answer, just some help to understand why the Deposit button will give the error but the Withdraw button won't show either error.

I'm trying to build a tooltip with shadow like the following image:

I was able to do so by using an Image as background. But I couldn't apply shadows to it. So, after searching I found this article, it uses MaterialCardView and applying MaterialShapeDrawable to it as a background.

I have tried the following code:
