我有一个浪费时间的问题。直到昨天我一直在为我的项目做得很好。昨天早上我开始工作时，遇到了这个问题;

“二进制XML文件第2行：膨胀类android.support.v7.widget.CardView时出错”

我突然用谷歌搜索，我看到其他人也面临着。但是关于这些问题的答案不是我的解决方案。它没有解决我的问题。请保存我的一天:)

这是我的礼物；

这是我的xml文件； 

 <?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="200dp"
    app:cardElevation="4dp">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <com.flaviofaria.kenburnsview.KenBurnsView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/backround_main_page"
            android:id="@+id/menu_image"
            android:scaleType="centerCrop" />

        <TextView
            android:fontFamily="@font/fondamento"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/menu_name"
            android:text="Menu Name"
            android:textColor="@color/white"
            android:background="#4f0e0d0e"
            android:textSize="20sp"
            android:gravity="center"
            android:layout_alignParentBottom="true" />
    </RelativeLayout>
</android.support.v7.widget.CardView>

这是我的viewHolder; 

public class MenuViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{

public TextView txtMenuName;
public KenBurnsView menu_image;
private ItemClickListener itemClickListener;

public MenuViewHolder(View itemView) {
    super(itemView);
    txtMenuName = itemView.findViewById(R.id.menu_name);
    menu_image = itemView.findViewById(R.id.menu_image);
    itemView.setOnClickListener(this);
}

public void setItemClickListener(ItemClickListener itemClickListener) {
    this.itemClickListener = itemClickListener;
}

@Override
public void onClick(View view) {
itemClickListener.onClick(view,getAdapterPosition(),false);
}

}

这是我的适配器； 

Query query = FirebaseDatabase.getInstance()
            .getReference().child("Category");
    FirebaseRecyclerOptions<Category> options = new FirebaseRecyclerOptions.Builder<Category>().setQuery(query, Category.class).build();
    adapter = new FirebaseRecyclerAdapter<Category, MenuViewHolder>(options) {
        @NonNull
        @Override
        public MenuViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
            View view = LayoutInflater.from(parent.getContext())
                    .inflate(R.layout.menu_item, parent, false);
            return new MenuViewHolder(view);
        }

        @Override
        protected void onBindViewHolder(@NonNull MenuViewHolder viewHolder, int position, @NonNull Category model) {
            viewHolder.txtMenuName.setText(model.getName());
            Picasso p = Picasso.get();
            p.load(model.image).into(viewHolder.menu_image);

            final Category clickItem = model;
            viewHolder.setItemClickListener(new ItemClickListener() {
                @Override
                public void onClick(View view, int position, boolean isLongClick) {
                    Toast.makeText(Home.this, "" + clickItem.getName(), Toast.LENGTH_SHORT).show();
                    Intent food_intent = new Intent(Home.this, FoodList.class);
                    //Because categoryId is key , so we just get key of this item
                    food_intent.putExtra(getCategoryId, adapter.getRef(position).getKey());
                    food_intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    startActivity(food_intent);
                }
            });
        }
    };
  adapter.startListening();

答案 0 :(得分：0)

删除xml中的起始空间。（仅在<?xml version="1.0" encoding="utf-8"?>之前） 原因：Xml声明应位于所有文档内容之前。
