Fab有時只會關注焦點

Question

我有一個問題，用D-pad測試我的應用程序的焦點問題。這裏有我的應用程序的兩張截圖：

在左側的畫面，晶圓廠是「外（或下）」列表中最後一個元素後，它會在焦點導航下來，所以在這種情況下一切都可以。問題出現在右側的圖像上。晶圓廠在listView「內部」，爲此（我認爲但是我不確定）它沒有得到關注。有什麼可以做的嗎？

不論工廠在佈局中的位置如何，問題在於我不願意將工作重點放在列表之前（緊接在選項卡之後）不知道該怎麼做，因爲Android決定了我的佈局的焦點順序。 任何幫助將不勝感激。

Answer 1

您可以創建一個單獨的Layout，並把你的工廠那裏。這將迫使這部分始終被看到。

例如

<LinearLayout> 
    //list stuff here 
    <LinearLayout> 
    //fab stuff 
    </LinearLayout> 
</LinearLayout>
