text does not scale in TextView

fun t(a: String): TextView {
            val textView = TextView(this)
            textView.text = a
            textView.setTextColor(Color.WHITE)
            textView.setAutoSizeTextTypeWithDefaults(TextView.AUTO_SIZE_TEXT_TYPE_UNIFORM)
            textView.setPadding(0, 0, 0, 0)
            textView.setTypeface(Typeface.MONOSPACE, Typeface.BOLD)
            return textView
        }

        AndroidToolkit.setup(this, R.drawable::class.java)
        val table = Table()
        table.tableLayout.debug()
        table.defaults().expand()
        table.add(t("a"))
        table.add(t("a"))
        Constraint.addView(table)

and buttons overlap

        table.add(android.widget.Button(this))
        table.add(android.widget.Button(this))

this is fixed for buttons by specifying both fill and expand but it does not work for textview as it aligns to the top left/right of the cell

Generally you size a root table to the entire area for your UI, then you add everything to that table. From the screenshots it looks like it is sized to the screen but to be sure, are you sizing the root-most table?

I'm afraid I don't have an Android development environment setup, so I can't test things right now. Also it's been a long time since I punished myself with Android's UI toolkit! If we can get you rolling with TableLayout though, much of the pain goes away.

BaseTableLayout uses AndroidToolkit#getPrefWidth/Height which is using view.getMeasuredWidth/Height() -- are those values what you'd expect? If they were large, it could explain why the buttons overlap: TableLayout thinks the button's preferred size is very large, larger than the available space.

Can you check AndroidToolkit.density? Does it help if you set it to 1 after calling setup?

this is confusing but ill try

setting AndroidToolkit.density to 1F (short for 1.toFloat() or 1 as Float )appears to help with the button overlap

https://s.amsu.ng/iJpYtBV1XR1N

        AndroidToolkit.setup(this, R.drawable::class.java)
        AndroidToolkit.density = 1F
        Constraint.addView(
            Table().also {
                it.tableLayout.debug()
                it.defaults().expand()
                it.add(Button(this))
                it.add(Button(this))
            }
        )

now, how to i make sure that i am sizing the root most table?

            }
        )

https://s.amsu.ng/TDVVVLJxcw4N

it may be due to the layout_weight, weightSum, and stretchColumns being unsettable in the api, im not sure

all i know is that TableLayout has

android:stretchColumns="*"
android:weightSum="4"

and TableRow has

android:layout_weight="1"

fun t(a: String): TextView = TextView(this).also {
            it.text = a
            it.setAutoSizeTextTypeWithDefaults(TextView.AUTO_SIZE_TEXT_TYPE_UNIFORM)
            it.setTypeface(Typeface.MONOSPACE, Typeface.BOLD)
            it.textAlignment = TextView.TEXT_ALIGNMENT_CENTER
            it.layoutParams = ViewGroup.LayoutParams(
                ViewGroup.LayoutParams.MATCH_PARENT,
                ViewGroup.LayoutParams.MATCH_PARENT
            )
        }

in which

        ConstraintOnly.addView(t("P"))

results in https://s.amsu.ng/gm0o3mJc2wqN
and

        ConstraintOnly.addView(
            Table().also {
                it.add(t("P"))
            }
        )

results in https://s.amsu.ng/MtMIFlFPyimN

setting AndroidToolkit.density to 1F (short for 1.toFloat() or 1 as Float )appears to help with the button overlap

OK. I don't remember what the density stuff was about, so I'll add a commit to keep it at 1.

it.tableLayout.debug()

Now that we have delegate methods, you can just use it.debug().

now, how to i make sure that i am sizing the root most table?

You use whatever Android UI stuff to make the root table the size you want, in the position you want.

I'm afraid the Android UI XML doesn't mean anything to me (that is some nasty stuff). The Android UI layouting is poor, TableLayout replaces it (once you have sized and positioned the root table). Also ConstraintOnly addView, LinearLayout, stretchColumns, layout_weight, etc are unfamiliar to me.

ok, can you give me an example of a root most table

Not any time soon, I don't have Android stuff setup (and I honestly hate it). Replace the table with a button (or ViewGroup or anything else). Make the button take up the whole screen (or whatever area you want for your UI). Once you have that working, replace the button with the table and that is your root table. Add the rest of your UI to the root table and mostly you never have to deal with nasty Android UI again.

Leave density=1.
