当我尝试在旧的物理设备和模拟器（API 19）上运行我的应用程序时出现此错误。但是，当我在我的主要物理设备（API 23）和API 22及更高版本的模拟器上运行时，我没有错误。
这是整个堆栈跟踪：

这是由我的主要活动xml布局上的第78行引起的，这是这段代码：
<SeekBar
android:id="@+id/seekbar_from_controller"
style="@style/SeekBarStyle"/>
这追溯到我的搜索栏样式，如下所示：
<style name="SeekBarStyle">
<item name="android:layout_width">match_parent</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:layout_marginLeft">5dp</item>
<item name="android:layout_marginRight">15dp</item>
<item name="android:max">14</item>
<item name="android:paddingBottom">5dp</item>
<item name="android:paddingTop">5dp</item>
<item name="android:progress">1</item>
<item name="android:thumb">@drawable/custom_thumb</item>
</style>
但是这会追溯到我的custom_thumb.xml，这是这段代码：
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<size
android:width="15dp"
android:height="15dp"/>
<solid android:color="?colorPrimary"/>
</shape>
我知道问题是我正在使用＆＃34;？colorPrimary＆＃34;因为我试图删除它并使用硬编码颜色，然后当我运行它时会再次导致错误，但是在另一个颜色为＆＃34;？colorPrimary＆＃34;
的元素上。有没有办法在不使用硬编码颜色的情况下解决这个问题？我需要使用＆＃34;？colorPrimary＆＃34;因为我可以选择更改应用程序的主题，这会更改主要颜色，重音颜色和主要颜色。
答案 0 :(得分：0)
使用
<solid android:color="@color/colorPrimary"/>
