我已经在我的应用程序中实现了材料设计,它在< Android 5但是当我尝试在Android 5.0及更高版本上运行时,我会在我的logcat中获得以下内容。

这是我的风格:
<resources>
<!--
Base application theme, dependent on API level. This theme is replaced
by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
-->
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
<style name="AppTheme" parent="@style/Theme.AppCompat.NoActionBar">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
<item name="colorPrimaryDark">#4DFF9800</item>
<item name="colorPrimary">#4D607D8B</item>
</style>
</resources>
如果有人能给我一些非常感谢的指导。

您不能在原色中使用alfa。原色必须是不透明的。
变化:
<item name="colorPrimaryDark">#4DFF9800</item>
<item name="colorPrimary">#4D607D8B</item>
要
<item name="colorPrimaryDark">#FF9800</item>
<item name="colorPrimary">#607D8B</item>
for res/values-v21/style.xml

答案 2 :(得分:0)
该问题的简单解决方案是删除colors.xml中应用于主要颜色的opaque
当不透明应用于原色时,颜色代码看起来像“#aca688ff”,它必须是ex:“#F50057”(6个字母的字母数字代码,不透明)。
希望上述解决方案可以帮助您解决问题。

错误 java.lang.RuntimeException:TaskDescription的原色应该是不透明的
答案: 转到您的应用->值->颜色,查看您的原色并计算该处的字符。它必须有六个六个字符(例如#FDEF25)。它不能超过六个字符。
