I am working on learning how to use all the different insets features of Android 11:
https://developer.android.com/reference/android/view/WindowInsets.Type
One of the things that always confuses me with insets is which ones are applicable to a specific scenario. Something that I would like to see that I think would be extremely useful is a visual diagram of which areas of the screen are defined by which insets, or a more detailed description of what each inset is (saying something like StatusBars is the insets for the status bars is NOT a description!). Can anybody recommend anywhere with more visuals or detailed descriptions as to exactly what each set of insets is?

I am looking for a grid / raster in Papyrus Neon, so I am able to align the components in my UML class diagram more precisely.
Is there such an option available? If so, where do I find it?
e.g. in ArgoUML such a grid is shown by default:
My research with Google was not successful either.
The easiest way to find properties like that is to use the search box at the top of the Properties drop-down menu. Type "grid" in there ant you will see that you can set diagrams that support grids an set your desired grid for each. Note tha the way to do this will change change slightly with Papyrus Oxygen, but the capability will remain.
Note that in the diagrams's toolbar, there are also actions to align model element representations (vertically/horizontally/spaced equally) or to make there sizes the same.
I tried to use UMLDesigner to draw my project related diagrams. I see there is a Arrange functionality that can automatically layout diagram elements and links to save some manual work. But when i used it in my Activity diagrams it designed it upside down.
Here is an example. I created following simple activity diagram.
And here is how auto layout result for the same model looks like: auto layout.
The initial node is at the bottom and the final nodes are on top. But i want it the other way - to start at the top and end at the bottom. Is there a way to configure this?
I tried pinning starting and final nodes but it just made a mess after arranging the rest automatically. I searched the settings but couldn't find anything. I use UML Designer Version 7.1.0.
Thanks ahead for any help.
I am sorry there is no way from the preferences to change this behaviour.
This is because I never provide a specific layout for this diagram. Please, fill an issue in the bug tracker and it will be fixed for the next version of UML Designer as it is really easy to fix: https://github.com/ObeoNetwork/UML-Designer/issues.
Thanks for your feedback!
Among all the ConstraintLayout attributes available in Android Studio 2.2, there are these two Bottom constrains and a Baseline constrain:
layout_constraintBottom_toTopOf
layout_constraintBottom_toBottomOf
layout_constraintBaseline_toBaselineOf
And it seems that not every view has baseline.
What's the difference and similarities between Bottom and Baseline constrain? Why do only certain views have a Baseline?
The official documentation lacks this kind of information.
EDIT
This image helps to understand baseline vs base:
Baseline is used for make view bottom to bottom of text
for example in EditText the text is not the bottom so
if you use baseline it will be in bottom of
EditText's text not EditText's view

In star UML I am trying to make my combined fragment overlap the timelines but even though I click "Move to top" or "move to back" on the timeline, the combined fragment keeps being covered:
When I watch this Tutorial the author doesnt seem to have this problem, as the combined fragment is on the top from the start.
I would appreciate all help really!
Unfortunately, this is not possible in the current version 2.7 of StarUML. The StarUML support has confirmed this limitation. They introduced a feature request to enable this in a future release.
So for the moment, the lifebar will always remain on top. You'll have to find a layout to avoid the overlaps.
Okay, so I'm really trying to do a lab for a class thing and I don't get why I can't have a textbox that takes up the width of the phone and a button that takes up the width of the phone on the bottom, but I don't know why that is? Here's a picture of what I have.
I know this is a noob question but it hasn't been addressed yet on the online course I'm taking and I really need an answer because I wanted android development to be as easy as .NET on windows.
Well anyway here is one picture:
Also here is the other picture:
Notice if I try to make one element bigger, it leads to it pushing the other one out of the activity, I want to have one activity with both elements taking up the entire width of the phone.
Does anyone know what I'm doing wrong?
EDIT: I'm using Ubuntu 14.04 not Mac OS X.
Your controls are children of a LinearLayout with android:orientation="horizontal". This means that the parent ViewGroup is aligning them horizontally; you cannot get the children aligned vertically in this configuration.
If you change the attribute to android:orientation="vertical", you will achieve the result you're looking for.
I strongly suggest getting yourself familiar with the default set of layouts available in the Android SDK by reading this official guide.
Edit : Please refer to this answer for placing views at bottom of the screen.
When you use a android:orientation=horizontal orientation in the layout, the views are stacked/placed in a single row. Since both your views have their width set to fill the screen, only the first one is shown/seen.
What you want is the vertical orientation. This places the views in a single column, one below the other. The width set to fill-parent will allow you the view to occupy all available space.
