Android < sdk 21 给出 InflateException

Question

我正在使用可绘制的状态列表来选择和取消选择 RecyclerView 中的项目行，但它在

风格：

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/my_color</item>
    <item name="colorPrimaryDark">@color/my_color</item>
    <item name="colorAccent">@color/my_color</item>
  </style>

我的项目布局：

<?xml version="1.0" encoding="utf-8"?>
  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="68dp"
    android:background="@drawable/item_sound"
    android:orientation="horizontal">

  </LinearLayout>

选择器可绘制drawable/item_sound.xml:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:drawable="@color/my_color" android:state_selected="true" />
  <item android:drawable="?android:attr/selectableItemBackground" android:state_selected="false" />
</selector>

例外：

我认为这与 <item android:drawable="?android:attr/selectableItemBackground" android:state_selected="false" /> 有关，但我找不到原因

为什么？

-------- 编辑 -----------

已经尝试过使用"?attr/selectableItemBackground"和"?android:attr/selectableItemBackground"，但什么也没有。

Answer 1

look at this answer

似乎无法为android:drawable 或android:src 使用主题属性

Answer 2

我最终为 v21 创建了一个可绘制对象，为

attributes in selectors didn't exist prior to API 21. At all. You can certainly create two different selectors, one in drawable and one in drawable-v21
