Android Listview в AutocompleteTextview не отвечает

Question

У меня проблема в моем приложении. Когда я пытаюсь выполнить поиск в своем приложении, и когда я нажму на предлагаемый список, он ответит, к сожалению, близко. Почему это ? Как это исправить ?

Я покажу вам свои коды и логарифм.

Answer 1

использование ClassCastException

Main item = (Main) adapter.getItem(position);

вместо

Main item = (Main) ((Menu) adapter).getItem(position); 

Редактировать

У вас есть два адаптер один локальная (тип String) другой глобальна (Основной тип)

autocomplete.setAdapter(this.adapter); 

не

autocomplete.setAdapter(adapter); 

здесь также используется локального переменного использование глобального

Main item = (Main) adapter.getItem(position); 

У вас есть два адаптера, один из которых локальный, а другой - глобальный

1. Global AnimalAdapter типа Main, является потомком BaseAdapter
2. Локальный ArrayAdapter типа Строка

Могу ли я узнать, почему эти два ??

Answer 2

попробовать:

Main item = (Main) parent.getAdapter().getItem(position); 

вместо:

Main item = (Main) ((Menu) adapter).getItem(position); 

ваш Arrayadapter initilization должно быть:

final ArrayAdapter<Main> adapter_new = new ArrayAdapter<Main> 
    (this,android.R.layout.simple_list_item_1, animalslist); 

    autocomplete.setAdapter(adapter_new); 

вы используете String в качестве параметра, который является неправильным
