如何在自己的Activity中去控制EditText的焦點

在進入一個Activity時，如果這個Activity中有EditText，則這個EditText會自動擷取焦點，然後就會彈出軟鍵盤，這樣給使用者體驗不是很好。是以一般會通過代碼控制讓EditText不擷取焦點。常用的方式如下，在Activity的布局檔案中加上如下代碼：

<!-- 輸入焦點控制 -->

    <LinearLayout
        android:layout_width="0px"
        android:layout_height="0px"
        android:focusable="true"
        android:focusableInTouchMode="true" />
           

在日前開發的一個項目中界面中除了EditText就是Spinner 和Button等空間，EditText 擷取焦點以後，點選Spinner總是無法移除焦點：采取如下方式解決，

當點選Spinner時讓EditText失去焦點即可：（見标紅代碼）
