android – proguard不保留匿名类

Could not find class ‘android.support.v7.widget.SearchView$5′,
referenced from method
android.support.v7.widget.SearchView.addOnLayoutChangeListenerToDropDownAnchorSDK11

我试图通过这个proguard配置来保持这个类：

-keepattributes Exceptions,InnerClasses,Signature,Deprecated,
                SourceFile,LineNumberTable,*Annotation*,EnclosingMethod

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

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

-keep class android.support.v7.widget.SearchView$5 {
    *;
}

但没有运气.这不是第一次proguard不通过配置保留成员,但这次我不能重写代码将匿名转换为内部类.

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