我有一个 TableLayout，我希望里面的元素（每个表格行都有一个文本视图）集中在触摸上。我将每个元素的可聚焦属性设置为 true，但它不起作用！

这是xml：

<?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="fill_parent"
android:layout_gravity="bottom"
android:focusable="true"
android:focusableInTouchMode="true"
android:gravity="right" >


<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentTop="true"
    android:background="#444444"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:gravity="bottom"
    android:orientation="vertical" >

    <TableLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:focusable="true"
        android:focusableInTouchMode="true" >

        <requestFocus />


        <TableRow

                android:textAppearance="?android:attr/textAppearanceMedium" />
        </TableRow>
    </TableLayout>
</LinearLayout>

我希望每个元素在用户触摸它时都成为焦点，知道为什么它在这里不起作用吗？

可绘制/table.xml

更新：

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_pressed="true"
           android:color="#993399" /> <!-- pressed -->
     <item android:state_focused="true"
           android:color="#993399" /> <!-- focused -->
     <item android:color="#222222" /> <!-- default -->

</selector>

这就是我在 main.xml 中引用它的方式

 android:src="@drawable/table1"

仍然没有任何事情发生

为您的列表视图项创建选择器，并设置其参数，例如：

<item android:drawable="@drawable/but" android:state_pressed="false" android:state_selected="false"/>
<item android:drawable="@drawable/butpressed" android:state_pressed="true"/>
<item android:drawable="@drawable/butpressed" android:state_pressed="false" android:state_selected="true"/>

在示例中我更改了图片，但您可以设置任何其他参数
