Android Listview поставил под вопрос «android.R.id.list»

Question

Я посмотрел те же случаи с моим, но могу его преодолеть :( Я получил это «В вашем контенте должен быть ListView с атрибутом id» android. R.id.list», когда я составил программу

Вот такие LogCat и коды

listfind.xml

    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 

    <ListView android:id="@+id/listview" 
     android:layout_width="match_parent"

    </ListView> 

</RelativeLayout> 

Answer 1

Поскольку вы используете ListActivity вы должны использовать идентификатор @android:id/list вместо пользовательского идентификатора в файле XML.

Чтобы разрешить эту проблему изменить listfind.xml от:

<ListView android:id="@+id/listview" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 
</ListView> 

в

<ListView android:id="@android:id/list" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 
</ListView>
