应用程序的发布版本不起作用

Question

我的 android 项目有问题。它似乎在调试模式下运行良好，但在发布模式下崩溃。我在我的项目中使用 firebase 和 google-account 注册。当我在注册后尝试从数据库中获取数据时，应用程序崩溃。我在我的 firebase 控制台中添加了发布密钥的 SHA-1 和 SHA-256 指纹，并在我的项目中更改了 google-services.json 文件。我不明白我做错了什么。错误：

java.lang.RuntimeException: java.lang.NoSuchMethodException: <init> [class android.view.View]

我也在我的项目中使用 customview - de.hdodenhof.circleimageview.CircleImageView

public class GroupAdapter extends RecyclerView.Adapter<GroupAdapter.MyViewHolderGroup> {

private List<GroupItem> mGroupItems;

public static class MyViewHolderGroup extends RecyclerView.ViewHolder{
    TextView group_name;
    LinearLayout mLayout;
    MyViewHolderGroup(View view) {
        super(view);
        group_name = (TextView) view.findViewById(R.id.group_card_text);
        mLayout = (LinearLayout)view.findViewById(R.id.field_of_push);
    }
}
public GroupAdapter(List<GroupItem> groupList) {
    this.mGroupItems = groupList;
}
@Override
public GroupAdapter.MyViewHolderGroup onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.group_card, parent, false);
    return new GroupAdapter.MyViewHolderGroup(itemView);
}
@Override
public void onBindViewHolder(final GroupAdapter.MyViewHolderGroup holder, int position) {
    GroupItem group = mGroupItems.get(position);
    holder.group_name.setText(group.getGroupname());
}
@Override
public int getItemCount() {
    return mGroupItems.size();
}
}

Answer 1

Probable causes:

这有两个可能的原因：

1. 确保您的 ViewHolder 类是公开的
2. 如果您的 ViewHolder 是一个内部类，例如您的活动，请确保它是静态的

And a little more:

ViewHolder（和 POJO 类）只有在嵌入时才必须是静态的 进入另一个班级。

对于内部类，Java 编译器会生成一个隐藏字段（以及 采用该字段的构造函数）以保持对包含的引用 对象，以便您可以在以下实例中执行 MainActivity.this 之类的操作 内部阶层。这个隐藏的字段/参数使 Firebase/FirebaseUI 中的反射代码以找到正确的构造函数。

将类标记为静态会删除隐含的字段/参数，所以事情 再次正常工作。或者你可以把 CommentViewHolder 在它自己的文件 CommentViewHolder.java 中。

更新：抱歉，我错过了问题的发布/调试部分。可能原因是混淆（proguard）。保留 ViewHolder 类。

更新 2：ViewHolder 构造函数也应该是公开的
