如何在自己的Activity中去控制EditText的焦点

在进入一个Activity时，如果这个Activity中有EditText，则这个EditText会自动获取焦点，然后就会弹出软键盘，这样给用户体验不是很好。所以一般会通过代码控制让EditText不获取焦点。常用的方式如下，在Activity的布局文件中加上如下代码：

 <!-- 输入焦点控制 -->

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

在日前开发的一个项目中界面中除了EditText就是Spinner 和Button等空间，EditText 获取焦点以后，点击Spinner总是无法移除焦点：采取如下方式解决，

当点击Spinner时让EditText失去焦点即可：（见标红代码）
