How to add a check box to an alert dialog

Question

Currently when the user opens my app, an AlertDialog opens, asking them if they would like to upgrade to the pro version.

I need to add a CheckBox

You could use a multichoicelist with only one item:

final boolean[] checked = new boolean[] {false};
builder.setMultiChoiceItems(new String[]{"Remember decision"}, checked, new DialogInterface.OnMultiChoiceClickListener() {
               @Override
               public void onClick(DialogInterface dialogInterface, int i, boolean b) {
                   checked[i] = b;
               }
           });

Then in the OnClick() of an alert dialog button you can check the value of checked[0]and save that value in your app's Sharedpreferences:

builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
                   @Override
                   public void onClick(DialogInterface dialogInterface, int i) {
                       if(checked[0]){
                           SharedPreferences.Editor editor = settings.edit();
                           editor.putBoolean("preferences_never_buy_pro", true);
                           editor.apply();
                       }
                       dialog.cancel();

                   }
               });

With this preference you can decide whether the dialog should be shown again in the future.
