Alert Dialog doesn't show radio buttons

Question

I have an alertDialog with the following code :

AlertDialog.Builder b = new AlertDialog.Builder(Activity.this);
String[] types = getResources().getStringArray(R.array.text_spinner_NewClass_dayList);
b.setSingleChoiceItems(types, 2, (dialog, which) -> {
            textView.setText(types[which]);
            dialog.dismiss();
        }
);
b.show();

I want to show all radio buttons of items but it only shows the selected item.

Create a xml layout as you want. And inflat that layout to alert dialog through View.

AlertDialog.Builder b = new AlertDialog.Builder(Activity.this);

//Your customized layout
final View customLayout = getLayoutInflater().inflate(R.layout.custom, null);

b.setView(customLayout);

b.show();

Try to change the Theme color for alert dialog. May be the inactive radio button is white. – charlie.7 Sep 12 '21 at 11:35
Yes you are right, when I change the theme color, all the radio buttons are shown. Thank you – Nima Khalili Sep 12 '21 at 11:44

According to my tests you can achieve it with MaterialAlertDialogBuilder or AlertDialog.Builder by setting setSingleChoiceItems

...

private var selectedFruitsIndex: Int = 0
private val fruits = arrayOf("Apple", "Banana", "Coconut", "Orange")

    MaterialAlertDialogBuilder(this)
            .setTitle("List of Fruits")
            .setSingleChoiceItems(fruits, selectedFruitsIndex) { dialog_, which ->
                selectedFruitsIndex = which
                selectedFruits = fruits[which]
            }
            .setPositiveButton("Ok") { dialog, which ->
                Toast.makeText(this, "$selectedFruits Selected", Toast.LENGTH_SHORT)
                        .show()
            }
            .setNegativeButton("Cancel") { dialog, which ->
                dialog.dismiss()
            }
            .show()
