我正在尝试实现这个库。这里编写的示例代码是用 Kotlin 编写的，但我的项目是用 Java 编写的，所以我尝试将代码从 kotlin 转换为 java。但我收到以下错误：
android.view.InflateException: Binary XML file line #2: Binary XML file line #2: Error inflating class androidx.cardview.widget.CardView 原因：android.view.InflateException: Binary XML file line #2: Error inflating class androidx .cardview.widget.CardView 引起：java.lang.reflect.InvocationTargetException at java.lang.reflect.Constructor.newInstance0(Native Method)
在给cardview充气
class CardStackAdapter extends RecyclerView.Adapter<CardStackAdapter.ViewHolder> {
private Context context;
private ArrayList<Spot> listItem;
public CardStackAdapter(Context applicationContext, ArrayList<Spot> listItem) {
this.context = applicationContext;
this.listItem = listItem;
}
@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.test, parent, false); // ----> I am getting error here..
return new ViewHolder(context, view);
}
@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
final String name = listItem.get(position).name;
String url = listItem.get(position).URL;
String city = listItem.get(position).city;
holder.name.setText(name);
holder.city.setText(city);
Picasso.get().load(url).into(holder.image);
holder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(context, name, Toast.LENGTH_SHORT).show();
}
});
}
@Override
public int getItemCount() {
return listItem != null ? listItem.size() : 0;
}
public void setItem(ArrayList<Spot> listItem){
this.listItem = listItem;
}
public ArrayList<Spot> getItem(){
return listItem;
}
class ViewHolder extends RecyclerView.ViewHolder {
TextView name;
TextView city;
ImageView image;
ViewHolder(Context context, View view) {
super(view);
this.name = view.findViewById(R.id.item_name);
this.city = view.findViewById(R.id.item_city);
this.image = view.findViewById(R.id.item_image);
}
}
}
我的这个 cardview 的 XML 代码是：

我已经在 Github Repository上上传了这个项目。任何建议都是最受欢迎的。谢谢！
