Horizontally and vertically scrollable layout in react native

I am trying to configure table grid layout in react native which could be scrollable horizontally and vertically.
By table grid layout I mean the layout similar to html table/tr/td: all views in the same row should have the same height and all views in the same column should have the same width.
The height of the row should be selected based on the height of the biggest view in the row.
The width of the column should be selected based on the width of the biggest view in the column.
I've started with horizontal scrolling.
This is what I've done:

While it looks fine for me in the browser, on my device in looks this way:
The biggest column takes as much space as it needs and the rest of the space is shared between other columns. But it is done for each row independently, so columns border floats. Ideally, I want Row 1, Col 1 and Row 2, Col 1 to be the same size as Row 3, Col 1. That does not work as they and in different rows.
Well, obvious idea is to switch to column base layout, right:

Again, in the browser, it looks different. On the device it looks this way:
On the first look, this is exactly what I want! But apparently, it just moves the problem to another dimenstion. Let's make one View higher than the others, add a vertical ScrollView and we are losing row layout now:
https://snack.expo.io/#grekonstudio/05_same_problem
You can see the bigger cell takes all space and the rows are not having the same size anymore :(
Additionally, I tried two more things:
setting the flex: 1 to Scroll's view contentContainerStyle.
https://snack.expo.io/#grekonstudio/02_flex_1
In this case, it does not scroll at all.
Getting device height and width and fixing the size of the scroll view contentContainerStyle
https://snack.expo.io/#grekonstudio/03_fixed_width
In this case 'flex: 1' works as it works without a scroll view: splitting it to equal size boxes, while I want rows and cols to be adjusted by content
Another disadvantage is hardcoding width: 2 * screenWigth as e.g. for small content I might not need 2 screen width, I might need 1.5 or 1.2 only. It would also not work in portrait easlity.
I've also tried using the DataTable component https://callstack.github.io/react-native-paper/data-table.html, but when added to horizontal scroll view it fails to keep table layout the same way as in my first image: cells in the same column have different width.
Does anyone have a solution for the above?

android GridLayout divider row

I'm trying to implement a tabular layout that has a header and a bunch of rows underneath it. I've chosen the GridLayout (android.support.v7.widget.GridLayout) as there's some requirements for some elements to span multiple columns (but those are of no concern to the question).
My header cells each contain a LinearLayout with a bunch of TextViews, they're dynamically filled in code,for the sake of example, have a look at the image below.
The second row should contain the divider which is a simple view, that should span my header columns (3).
The problem is the width of the divider - if I choose MATCH_PARENT, it will push the GridLayout to fill the whole remaining space to the right. The grid needs to wrap the content and center itself horizontally. It seems to me there's a conflict between the grid's layout (WRAP_CONTENT) and the divider's layout (MATCH_PARENT).
How can I fix the width of the divider without hardcoding it?

In red, my LinearLayouts (header), green, the GridLayout itself, the thin blue line at the bottom is the divider.
Thanks,

SOLUTION (as provided below):
I had to set the column weight for the divider to 1, without specifying a width (actually setting it to zero). Because of my specific requirement to handle all of these in code, the solution was to manually instantiate the GridLayout.LayoutParams class and use
ColumnSpec = GridLayout.InvokeSpec(row_index, num_spanned_cols, weight)
Hope this helps others in the future.

If you set the width to 0dp then give it android:layout_weight="1"
(you could give it any weight you want) it should fill all the available space and not push your bounds if I understand what you are asking correctly

Android: Placing a TextView centered around a specified position in XML

I have a TextView that can have a few different values, and is updated runtime (in Java code).
However, I need this TextView to retain its center point, so that when the text in that TextView is updated, it is always center justified. It should be centered around a point which is not the center of the screen or anything else, so setting gravity only will not help.
As the values that it may contain are already defined, I could try with the longest one first, position it to the correct top left position and set its gravity to center. In this case every shorter in length text should fit correctly.
However, I would like to know if there is better approach, for cases when the values are not known beforehand.
This TextView is placed below an ImageView and it could take the whole screen width (nothing else is placed left or right to it).
Note: I guess it could be also possible to position it every time to a new X axis position, whenever the text is changed, but I don't think it is a nice solution at all.

Set the android:layout_width to match_parent and set android:gravity to center_horizontal.
This way the View is stretched all the way horizontally, and the content (the text) will be centered. If the content changes, it will still be centered.
One thing that many people don't realize is the difference between android:gravity and android:layout_gravity. The first one defines the alignment of the content inside itself, the other one defines alignment of itself relative to its parent.

Setting column width in Table View

I am having a hard time understanding how to change the width of columns when creating a table view.
I know you can set the width in pixels of a column but that is not what I want to do.
Say, for instance, I have 2 columns and want each column to take up half the screen. How do I do this without explicitly setting the pixels, so that my code can work on multiple screen sizes?

With a TableLayout? You can't do that easily. The closest you can get is to use android:stretchColumns="*" on your TableLayout element. That should allocate any extra whitespace evenly between the two columns.

Just set the TableRow layout_width="0dip"
and then set the two column layout_weight="1"
This will help you evenly divide a row.

Android Stretch columns evenly in a TableLayout

I am displaying a table of values in my android application, and would like the columns to be distributed evenly in terms of size , instead of sizing according to content.
Been playing around with stretchColumns but couldn't manage to figure out the right combination, Any Ideas?

I had the same problem - I always only entered one number in android:stretchColumns, but you have to enter all columns that should be stretched. So if you have three columns, you have to write:
android:stretchColumns="0,1,2"
Or write:
android:stretchColumns="*"
Then all columns will have the same size. As a reminder, android:stretchColumns is an attribute for the TableLayout element.

You need to set BOTH android:layout_width="0dip" and android:layout_weight="1" for each view within a table row. I think this works because the weights determine the proportion of the EMPTY SPACE in the row used by the respective views, and since the width of all views is set to 0dip, the whole row is empty space, and hence with equal weights the views are all allocated the same proportion of the WHOLE width.

Use the android:layout_weight for the columns

You control the size of the columns by the size of their contents. If you want them all to be the same size, set that up via android:layout_width in the appropriate cells.

Whoever is still looking for solution, for me:
setting columns both shrinkable and stretchable did the trick.
I had pretty much the same problem as OP.
