Set Height of Alert Dialog-CodePudding

I have 2-3 radio buttons in my alert dialog but the size of the dialog is not wrapping them up even though the screen could easily fit them instead putting them in a small layout with scroll view.

I referred to this question

Code:

AlertDialog.Builder(requireContext()).setTitle("Choose Address")
        .setSingleChoiceItems(addresses, selectedItemIndex) { _, which ->
            selectedItemIndex = which
        }.setPositiveButton("Confirm Address") { dialog, _ ->
            confirmBooking(selectedItemIndex   1, user)
            dialog.dismiss()
        }.setNeutralButton("Cancel") { dialog, _ ->
            dialog.dismiss()
        }.show()
        .window?.setLayout(
            (resources.displayMetrics.widthPixels * 0.9).toInt(),
            (resources.displayMetrics.heightPixels * 0.7).toInt()
        )

I wanted to use MaterialAlertDialog but that was also giving the same results. I do not want to use a custom dialog. How can I solve this height problem?

Please comment if any other information is required. I will be grateful for any help. Thanks in advance.

If you want dialog size to grow with content height. Then it's basically a wrap content. You can apply ViewGroup.LayoutParams.WRAP_CONTENT to your height.

Following is the slight modification to your code snippet:

    val addresses = arrayOf("1", "2", "3","4","5","6")
    var selectedItemIndex = 0
    private fun showDialog() {

        AlertDialog.Builder(this).setTitle("Choose Address")
            .setSingleChoiceItems(addresses, selectedItemIndex) { _, which ->
                selectedItemIndex = which
            }.setPositiveButton("Confirm Address") { dialog, _ ->
                dialog.dismiss()
            }.setNeutralButton("Cancel") { dialog, _ ->
                dialog.dismiss()
            }.show()
            .window?.setLayout(
                (resources.displayMetrics.widthPixels * 0.9).toInt(),
                ViewGroup.LayoutParams.WRAP_CONTENT
            )

    }

Output:

For what it's worth, using your code (just the dialog builder, not the window-tweaking bit at the end) I get:

import android.app.AlertDialog - expands properly at Default font size in the system settings, stays small and scrolls at Largest. (Almost like it's trying to maintain a consistent size, based on the space needed for Default)

import androidx.appcompat.app.AlertDialog - expands properly at Default and Largest

That's using appcompat:1.4.0 with an old test project on an API 30 emulator, should be the same on the latest version I expect!
