Android Gridview получение фокуса

Question

У меня есть линейная компоновка, а у самого дна у меня есть gridview (hotelsGrid), что я заполняю больше предметов, чтобы увидеть, проблема в том, что после того, как я установил свой адаптер, вид на экране переходит на снизу, чтобы показать gridview, и мне нужно оставаться на вершине, как я могу архивировать это?

Вот мой XML:

Answer 1

добавить к вашему верхнему уровню Layout View --Linearlayout. чтобы сделать его foucsable

<LinearLayout 
android:id="@+id/top_layout" 
android:focusable="true" 
android:focusableInTouchMode="true"> 

В настоящее время в деятельности:

LinearLayout layout = (LinearLayout) findViewById(R.id.top_layout); 
layout.requestFocus(); 

вызов layout.requestFocus(); после и есть Настраивает адаптер
