旧手机充气布局错误

Question

这段代码在Nexus 5/Lollipop5.1上运行良好，但是当我尝试在糟糕的LG E615f/ICS 4.0.4上运行时，这个奇怪的错误就开始发生了。

下面是它抱怨的ImageButton：

<ImageButton
        android:id="@+id/taskItemDownloadBtn"
        android:layout_width="@dimen/listItemIconSize"
        android:layout_height="@dimen/listItemIconSize"
        android:layout_gravity="center"
        android:src="@drawable/ic_cloud"
        android:background="@drawable/ripple"
        android:contentDescription="@null" />

而ripple.xml的两个版本并没有发现：

drawable/ripple.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape android:shape="rectangle">
            <corners android:radius="16dp" />
            <solid android:color="?colorControlHighlight" />
        </shape>
    </item>
</selector>

drawable-v21/ripple.xml

<?xml version="1.0" encoding="utf-8"?>
<ripple
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="?colorControlHighlight"/>

我试着：

• 将组件从ImageButton更改为ImageView和Button，但没有成功；
• 清洁项目；
• 删除可绘制的背景；
• 再清洁一下这个项目

Answer 1

发现问题了。实际上是drawable/ripple.xml。当我删除它时，在具有相同问题的其他可绘制XML中发生了错误。

在可绘制的XML中，旧的Android似乎不能解释属性引用，例如：?colorAccent和?attr:colorControlHighlight，只能在布局XML中解释。必须退到那里直接引用颜色：

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape android:shape="rectangle">
            <corners android:radius="16dp" />
            <solid android:color="@color/makara" />
            <!-- `?colorControlHighlight` does not work here -->
        </shape>
    </item>
</selector>

谢谢那个提出这个建议的人，他后来删除了答案！

Answer 2

这个问题是由ResourcesNotFoundException引起的。

Caused by: android.content.res.Resources$NotFoundException: File res/drawable/ripple.xml from drawable resource ID #0x7f0200b

尝试在ripple.xml文件夹中添加文件/drawable。

*-如果您已经拥有该资源，只需刷新项目并重新构建，以确保将资源ID #0x7f0200b添加到R.java文件中。

的问题是:属性：

 android:color="?colorControlHighlight"

是在API 21中添加的。
