In short on run time permissions dialog, you can't customize it.

When your app calls requestPermissions(), the system shows a standard dialog box to the user. Your app cannot configure or alter that dialog box. If you need to provide any information or explanation to the user, you should do that before you call requestPermissions(), as described in Explain why the app needs permissions.’

If you want to change the background of alertdialog, use belwo code: Add this line and you will able to change the background color of alert dialog.

        AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
                        builder.setTitle("Say Hello!");
                        builder.setMessage("Are you want to do this?");
                        AlertDialog dialog = builder.create();
                        dialog.show();

              dialog.getWindow().setBackgroundDrawable(newColorDrawable(Color.Blue));

  • When you wanna get runtime permission , alert dialog appears automatically. Alert dialog backgorund and text colors are white. This is problem. İ just wanna change alert dialog color to eliminate this problem – emowise Oct 08 '18 at 11:20
  • yes but: it says: can not resolve symbol: alertDialog – emowise Oct 08 '18 at 11:30
  • instead alertdialog use your local instance name of Alert dialog class that u have used.. – Chetan Ansel Oct 08 '18 at 11:37

You want to change runtime permission request dialog colors I suppose. You can't customize those alert dialogs. They are default.

Take a look into this answer: How can I customize permission dialog in Android?
