无法将选择器设置为RadioButton的背景

Question

当我试图将选择器设置为RadioButton的背景时，遇到了一个奇怪的错误
我的布局很简单：

<android.support.v4.view.ViewPager
    android:id="@+id/viewpager"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" />
<RadioGroup
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >
    <RadioButton
        android:id="@+id/rbtnPhoto"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@drawable/icon_photo_selector" />
    <RadioButton
        android:id="@+id/rbtnTagline"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@drawable/icon_tagline_selector" />
    <RadioButton
        android:id="@+id/rbtnTranslator"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@drawable/icon_translator_selector"/>
    <RadioButton
        android:id="@+id/rbtnDiscount"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@drawable/icon_discount_selector" />
</RadioGroup>

我的选择是：

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/icon_photo_selected" android:state_checked="true"></item>
    <item android:drawable="@drawable/icon_photo_unselected" android:state_checked="false"></item>
</selector>

上面是九个路径图像。我总是得到一个异常，它是"android.view.InflateException：二进制XML文件行"。但是，如果我通过图像更改选择器，布局可能会膨胀
请帮我解决这个问题。
更新：
我的图像是不错的补丁图像
这是我的日志：

Answer 1

将选择器更改为：

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

选择器标签似乎缺少

Answer 2

您忘记了<selector>-标签：

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

我认为这应该可以解决您的问题
