问题描述

我已经在我的应用程序中实现了材料设计，它在 < 上运行得非常好.Android 5 但当我尝试在 Android 5.0 及更高版本上运行时，我的 logcat 中出现以下内容.

I have implemented material design into my app and it runs perfectly fine on < Android 5 but when I try to run on Android 5.0 and above I get the following in my logcat.

     FATAL EXCEPTION main

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指导，那将非常感谢.

If anyone could give me some guidance that would be great thanks.

推荐答案

不能在原色中使用 alfa.原色必须是不透明的.

You can not use alfa in primary color. The primary color has to be opaque.

变化:

<item name="colorPrimaryDark">#4DFF9800</item>
<item name="colorPrimary">#4D607D8B</item>

到

<item name="colorPrimaryDark">#FF9800</item>
<item name="colorPrimary">#607D8B</item>

对于 res/values-v21/style.xml 文件中的 api 21

for api 21 in res/values-v21/style.xml file
