android:descendantFocusability

Defines the relationship between the ViewGroup and its descendants when looking for a View to take focus.

Must be one of the following constant values.

Constant	Value	Description
`beforeDescendants`	0	The ViewGroup will get focus before any of its descendants.
`afterDescendants`	1	The ViewGroup will get focus only if none of its descendants want it.
`blocksDescendants`	2	The ViewGroup will block its descendants from receiving focus.

解决方案

在ListView要显示的Item的外层加上

    android:descendantFocusability="blocksDescendants"

这段代码

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" 
    android:descendantFocusability="blocksDescendants">

    <TextView
        android:id="@+id/checkinfo_item_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_gravity="left"
        android:textColor="@android:color/black"
        android:textSize="25sp" />

    <Spinner
        android:id="@+id/checkinfo_item_value"
        style="@style/SpinnerAsEditText"
        android:layout_width="125dip"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:focusable="false" />

</RelativeLayout>
