Android Несколько элементов выберите элемент, используя кнопку и диалоговое окно, и отобразите выбранный элемент в списке, а не кнопку

Question

Я пытаюсь сделать Android Multiple select item с помощью кнопки и диалогового окна и отобразить выбранный элемент в виде списка (как на картинке) вместо кнопки (ток отображается в кнопке: см фото)

я могу отобразить приемник в кнопке ниже, но я хочу то же, которое будет отображаться в списке:

показывает после выбора из диалогового флажка, как :

"Receiver1, Receiver2" 

Я хочу люблю:

image of Receiver1 with Receiver1 Name 
image of Receiver2 with Receiver2 Name

копировать и вставить выше code..when Вы регистрируетесь в диалоге это автоматический add in listview

Answer 2

Ниже код будет работать для вас:

String[] your_array = {"a","b","c"} 
     adapter = new ArrayAdapter<String>(this, 
       android.R.layout.simple_list_item_multiple_choice, your_array); 
     listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE); 
     listView.setAdapter(adapter); 

Использование вышеуказанного кода Вы можете отмечать-непроверено в виде списка.
