v7支持23.0.1崩溃:AppCompatButton.setBackgroundDrawable

Question

我遇到了这个崩溃,支持库23.0.1

在显示Dialog Fragment时会发生这种情况.

它验证既android.support.v4.app.DialogFragment和android.support.v7.app.AppCompatDialogFragment

其他人都在经历这个？

它总是在发布编译(启用了Proguard)时发生,并且仅在某些情况下使用调试编译.

我正在报告两个片段类的崩溃堆栈.

用于android.support.v4.app.DialogFragment的堆栈:

Answer 1

根据这个,如果您使用appcompat-v7,您的proguard设置应该包含以下规则:

-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);
}

使用SearchView和我想象的其他东西时,这也可以避免麻烦.
