Question

我有一个TableLayout，我希望内部的元素（每个表行都有一个文本视图）集中在触控上。我将每个元素的focusable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:id="@+id/tableRow1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="#993399"
            android:clickable="true"
            android:focusable="true"
            android:focusableInTouchMode="true" >





            <TextView

                android:layout_width="match_parent"

我希望每个元素在用户触摸时都是焦点，知道为什么它不在这里工作吗？

抽拉/ 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"

仍然没有发生任何事情

Answer 1

为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

焦点表行不起作用
