应用程序>资源>值>Colors.xml - 我已经为 RippleEffectColor

创建了颜色

<resources>
     <Color name="rippleEffectColor">#F816A463</Color>
</resources>

App>Res>Drawable
    <?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    **android:color="@color/rippleEffectColor"**
    tools:targetApi="lollipop"
    >
    <item>
        <shape android:shape="rectangle">
           <solid android:color="@color/btnSignIn"></solid>
           <stroke android:color="color/btnSignIn" android:width="2dp"></stroke>
           <corners android:radius="2dp"/>
       </shape>

</ripple>

但我一直在 android:color="@color/rippleEffectColor"

您的代码中有两个拼写错误。我运行它是这样的，它正在工作：

<resources>
     // color has to be lower case
     <color name="rippleEffectColor">#F816A463</color> 
</resources>


<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:color="@color/rippleEffectColor"
    tools:targetApi="lollipop"
    >
    <item>
        <shape android:shape="rectangle">
           <solid android:color="@color/btnSignIn"></solid>

           //The @ sign was missing before color
           <stroke android:color="@color/btnSignIn" android:width="2dp"></stroke>
           <corners android:radius="2dp"/>
       </shape>
    </item>

</ripple>
