Question

Kotlin

Hi all. There is a layot'a (popup window) code, how can I display it in activity_main.xml when the button is clicked?

First, draw a Layout and call it policy_popup (for this example, or whatever you want)

    </ScrollView>

</androidx.constraintlayout.widget.ConstraintLayout>

Then somewhere in the Main Activity code write

public void policytextshow(){
        LayoutInflater li = LayoutInflater.from(this);
        View promptsView = li.inflate(R.layout.policy_popup, null);
        //Make AlertDialog
        AlertDialog.Builder mDialogBuilder = new AlertDialog.Builder(this);
        //Настраиваем .xml для нашего AlertDialog:
        mDialogBuilder.setView(promptsView);
        //Настраиваем отображение поля для ввода текста в открытом диалоге:
        //Настраиваем сообщение в диалоговом окне:
        CheckBox hidebox = (CheckBox) promptsView.findViewById(R.id.donotshow);
        mDialogBuilder
                .setCancelable(false)
                .setIcon(R.drawable.shield1)
                .setTitle("Политика информации")
                .setPositiveButton("OK",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,int id) {
                                if (hidebox.isChecked()) {
                                    SharedPreferences.Editor editor = mSettings.edit();
                                    editor.putString(APP_PREFERENCES_SHOWPOLICY, "1");
                                    editor.apply();
                                }
                                dialog.cancel();
                                // if policy alert dialog closed - work with contacts list
                                contacts();
                            }
                        });
        //Создаем AlertDialog:
        AlertDialog alertDialog = mDialogBuilder.create();
        //и отображаем его:
        alertDialog.show();

        LayoutInflater li1 = LayoutInflater.from(this);
        View promptsView1 = li1.inflate(R.layout.data_popup, null);
        //Make AlertDialog
        AlertDialog.Builder mDialogBuilder1 = new AlertDialog.Builder(this);
        //Настраиваем .xml для нашего AlertDialog:
        mDialogBuilder1.setView(promptsView1);
        //Настраиваем отображение поля для ввода текста в открытом диалоге:
        //Настраиваем сообщение в диалоговом окне:
        mDialogBuilder1
                .setCancelable(false)
                .setIcon(R.drawable.shield1)
                .setTitle("Используемые данные")
                .setPositiveButton("OK",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog1,int id) {
                                if (hidebox.isChecked()) {
                                    SharedPreferences.Editor editor = mSettings.edit();
                                    editor.putString(APP_PREFERENCES_SHOWPOLICY, "1");
                                    editor.apply();
                                }
                                dialog1.cancel();
                            }
                        });
        //Создаем AlertDialog:
        AlertDialog alertDialog1 = mDialogBuilder1.create();
        //и отображаем его:
        alertDialog1.show();
    }

According to this code, first one message pops up, then, when you click on OK, the second one, then it closes.
