使用Proguard混淆后，CardView阴影未出现在棒棒糖中

问题描述

应用Proguard后，我的CardView阴影在Lollipop设备上消失了.我没有定义任何保护该库的规则，因为我根本没有读过它.

My CardView's shadows have disappeared on Lollipop devices after applying Proguard. I haven't defined any rule to protect this library, because I haven't read it was necessary at all.

我附上了两个屏幕截图，首先是不运行proguard，然后是运行后的secon.

I attach you a couple of screenshots, first without running proguard, and secon after running it.

使用proguard截屏

这是我的xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:app="http://schemas.android.com/apk/res-auto"
            xmlns:tools="http://schemas.android.com/tools"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical"
            android:paddingLeft="@dimen/activity_horizontal_margin"
            android:paddingRight="@dimen/activity_horizontal_margin"
            android:paddingTop="@dimen/activity_vertical_margin"
            android:paddingBottom="@dimen/activity_vertical_margin"
            tools:context=".MainActivity">

    <android.support.v7.widget.CardView
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:layout_margin="4dp"
        app:contentPadding="10dp"
        app:cardUseCompatPadding="true">
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Text 1"/>
    </android.support.v7.widget.CardView>

    <android.support.v7.widget.CardView
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:layout_margin="4dp"
        app:contentPadding="10dp"
        app:cardUseCompatPadding="false">
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Text 2"/>
    </android.support.v7.widget.CardView>

</LinearLayout>

活动仅将xml设置为内容，并且仅执行其他操作.如您所见，我正在使用cardUseCompatPadding的两种可能性，但它不能解决问题，因为它在.

Activity only sets the xml as content and does nothing more.As you can see, I'm using the two possibilities of cardUseCompatPadding, but it doesn't solve the issue as it's defined in this thread.

有人知道为什么proguard破坏了我的阴影吗?

Does anybody know why proguard is breaking my shadows?

推荐答案

在库包中进行了一些潜水之后，我编写了一条规则来保护android.support.**上的所有内容，现在我终于只保护了android.support. .v7.widget.RoundRectDrawable.

After some diving in the library packages, I wrote a rule that protected everything at android.support.** and now I'm finally protecting just android.support.v7.widget.RoundRectDrawable.

因此，如果您对此有疑问，只需在您的proguard配置中添加下一条规则即可:

So if you are having troubles with this, just add the next rule at your proguard config:

-keep class android.support.v7.widget.RoundRectDrawable { *; }
