V7支持23.0.1崩潰：AppCompatButton.setBackgroundDrawable

我遇到此崩潰，以支持庫23.0.1V7支持23.0.1崩潰：AppCompatButton.setBackgroundDrawable

顯示一個對話框片段，當它發生。

它驗證既android.support.v4.app.DialogFragment和android.support.v7.app.AppCompatDialogFragment

任何人遇到此？

它始終發生在發佈編譯（啓用了Proguard），並且只在某些情況下使用調試編譯。

我正在報告這兩個片段類的崩潰堆棧。

堆棧android.support.v4.app.DialogFragment：

打開proguard映射文件並告訴我們什麼是'android.support.v7.widget.o.a（）'。你有沒有試過[this]（https://github.com/krschultz/android-proguard-snippets/issues/17）？ –

謝謝！我通過添加： '-keep public class android.support.v7.widget。** {*; } –

@EugenPechanec，我可以給你答案，如果你寫一個 –

根據到this如果您使用的是appcompat-v7，則您的proguard設置應該包含以下規則：

-keep public class android.support.v7.widget.** { *; } 
-keep public class android.support.v7.internal.widget.** { *; } 
-keep public class android.support.v7.internal.view.menu.** { *; } 

-keep public class * extends android.support.v4.view.ActionProvider { 
    public <init>(android.content.Context); 
}

這也可以幫助您避免在使用SearchView和其他我想象的事情時遇到麻煩。

這是說，除非你搞砸了proguard配置，你不需要這個（至少有25.x.x支持庫）。 –
