我有一个自定义 ListView，它的背景和文本项应该有颜色选择器。

我的清单中的自定义项目：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="5dp"
    android:paddingTop="5dp" >

    <ImageView
        android:id="@+id/user_image"
        android:layout_width="30dp"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/user_name"
        android:layout_alignTop="@+id/user_name"
        android:scaleType="centerInside" />

    <CheckedTextView
        android:id="@+id/user_name"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="2dp"
        android:paddingBottom="2dp"
        android:layout_marginLeft="5dp"
        android:layout_toRightOf="@+id/user_image"
        android:background="@drawable/list_item_selector_blue"
        android:textColor="@drawable/text_color_selector"
        android:textSize="18sp" />

</RelativeLayout>

我可以通过选择器更改 CheckedTextView 背景，但是当我将选择器放在这样的文本颜色中时android:textColor="@drawable/text_color_selector"，应用程序崩溃并出现以下错误：

我用谷歌搜索了很多，发现很多人有这样的问题，但任何提示都可以解决我的问题。

这些是我的选择器：

text_color_selector

<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item 
        android:state_selected="true"
        android:drawable="@android:color/white"/>
    <item 
        android:state_checked="true"
        android:drawable="@android:color/white"/>    
    <item
        android:drawable="@color/gray_text" />
</selector>

list_item_selector_blue

<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item 
        android:state_selected="true"
        android:drawable="@color/list_item_selected_blue"/>
    <item 
        android:state_checked="true"
        android:drawable="@color/list_item_selected_blue"/>    
    <item
        android:drawable="@android:color/white" />
</selector>

textColor 属性只能有一个颜色值。所以你不能在选择器 XML (text_color_selector.xml) 中定义 android:drawable。只需将drawable更改为颜色，这应该可以解决问题。至少它确实解决了我的这个改变的问题：

<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item 
    android:state_selected="true"
    android:color="@android:color/white"/>
  <item 
    android:state_checked="true"
    android:color="@android:color/white"/>    
  <item
    android:color="@color/gray_text" />
</selector>

我假设文本颜色只能包含一种颜色，而 drawable 允许您定义更多。
