在我的应用程序中，我们有一个显示的视图而不是ListView，以指示列表视图为空。它是从以下xml中膨胀的：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical">
<ImageView
android:id="@+id/view_empty_state_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:tint="?colorAccent" />
<Space
android:layout_width="match_parent"
android:layout_height="16dp" />
<TextView
android:id="@+id/view_empty_state_message"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textAllCaps="true"
android:textColor="?colorAccent"
android:textSize="@dimen/text_xxlarge" />
<Space
android:layout_width="match_parent"
android:layout_height="24dp" />
</LinearLayout>
最近，应用程序开始崩溃，使这个视图膨胀，产生了这个怪物堆栈：

很明显，问题是由＆＃34; tint＆＃34;中的样式引用引起的。 ImageView和TextView的属性（＆＃34;？colorAccent＆＃34;），因此我们将此引用更改为colors.xml文件的静态引用（现在属性值为＆＃34; @ color / accent＆＃34;）但是我很好奇什么可能导致问题首先？
答案 0 :(得分：1)
你使用了错误的符号。它不是
?colorAccent
您需要使用
?attr/colorAccent
代替。
答案 1 :(得分：0)
您可以直接将@color/colorPrimary用于您定义颜色的颜色 -
<color name="colorPrimary">#3F51B5</color>
的价值观。或者您需要将属性添加为
<attr name="colorPrimary" format="reference"/>
然后初始化为样式 -
<style name="AppTheme" parent="@android:style/Theme.Holo.Light.DarkActionBar">
<item name="attr/colorPrimary">@color/colorPrimary</item>
</style>
您可以使用?attr/colorPrimary
