FlowLayout | longer maintained ] Android streaming layout

For a Shiny app I want to display multiple selectInputs side by side in a Row like Layout in my app. Unfortunately the select fields do not line up if there is a line break within a label which destroys the flow of the app.

This is my example code, i modified the example in the description of selectInput:

I am trying to resize the center panel of my BorderLayout but the size is not changing. It keeps filling the rest of the frame that is available. I have tried setting the preferred size but has no effect. I would like how size of the frame but only need a portion of the center to be actually a panel for later use.

I want to be able to scroll down a dynamically generated list of movies. I tried adding a Scrollpane.

I have a navigation bar at the page start and in the center a jpanel with all the movies.

You can recreate this example by using this code:

After upgrading to android 12, the application is not compiling. It shows

"Manifest merger failed with multiple errors, see logs"

Error showing in Merged manifest:

Merging Errors: Error: android:exported needs to be explicitly specified for . Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details. main manifest (this file)

I have set all the activity with android:exported="false". But it is still showing this issue.

My manifest file:

I'm trying to create a program that lists movies in a Netflix style to learn Front-End coding.

How I want it to look in the end:

My guess is that every movie is a button component with an image a name label and a release year label.

I'm struggling to recreate this look. This is how it looks when I try it:

The navigationbar in my image is at the page start of a border layout. Below the navigationbar the movie container is in the center of the border layout.

My idea was creating a GridLayout and then create a button for each movie and adding it to the GridLayout.

You can recreate this with this code:

I am trying to implement an image appearing when a button is pressed. For this purpose I thought I could just copy the concept of button 4 (which works) and exchange the System.exit(0) with code to add an image, but while I've been able to use that code elsewhere successfully, here it does not seem to work.

I have pretty much copy pasted the code from http://people.apache.org/~clay/batik/svgcanvas.html but the svg that is outputing is blurry. I have used both a fontawesome and a material ui svg but both were blurry. What am i doing wrong? Here is my code:

I try to create a dynamic cell column from different iPhone devices with collectionView.

I already try for iPhone SE to have a 3 column and success, but when I try to make iPhone 11 Pro Max to have a 4 column it have a space between each cell.

iPhone 11 Pro Max

iPhone SE

I calculate my cell like this

What I achieved so far: I have a fully reproducible shiny app (using iris dataset) which makes dynamic plots (one does not know how many plots will output) based on one or more selected dropdown value(s) (Species in this case).

My question: I'd like to add a dynamic subtitle from a column called new. To elaborate, each Species has exactly two unique values (e.g., a and b for Species = setosa). Is there a way to add these unique values so that it could be integrated into the dynamic plots ?
