Question

我正在尝试在现有项目中使用RecyclerView，构建时没有错误，但充气时没有发现RecyclerView类错误。看不到我在做什么错。感谢您的帮助！

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

import androidx.recyclerview.widget.RecyclerView;
import java.util.ArrayList;

public class search_item1 extends RecyclerView.Adapter<search_item1.ViewHolder> {

    private ArrayList<String> mData = null ;

    // 아이템 뷰를 저장하는 뷰홀더 클래스.
    public class ViewHolder extends RecyclerView.ViewHolder {
        TextView textView1 ;

        ViewHolder(View itemView) {
            super(itemView) ;

            // 뷰 객체에 대한 참조. (hold strong reference)
            textView1 = itemView.findViewById(R.id.text2) ;
        }
    }

    // 생성자에서 데이터 리스트 객체를 전달받음.
    search_item1(ArrayList<String> list) {
        mData = list ;
    }

    // onCreateViewHolder() - 아이템 뷰를 위한 뷰홀더 객체 생성하여 리턴.



    @Override
    public search_item1.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        Context context = parent.getContext() ;
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) ;

        View view = inflater.inflate(R.layout.search2_item, parent, false) ;
        search_item1.ViewHolder vh = new search_item1.ViewHolder(view) ;

        return vh ;
    }

    // onBindViewHolder() - position에 해당하는 데이터를 뷰홀더의 아이템뷰에 표시.
    @Override
    public void onBindViewHolder(search_item1.ViewHolder holder, int position) {
        String text = mData.get(position) ;
        holder.textView1.setText(text) ;
    }

    // getItemCount() - 전체 데이터 갯수 리턴.
    @Override
    public int getItemCount() {
        return mData.size() ;
    }
}

请提供此代码的帮助直到我死的那一天，我仰望天空。我希望你不要羞愧即使在风中我很伤心。满怀星光的心爱所有垂死的。而且我得到的方式我必须走路。

今晚的星星再次在风中摩擦。

我有这样的错误：

Answer 1

用android.support.v7.widget.RecyclerView替换xml文件中的androidx.recyclerview.widget.RecyclerView

Answer 2

您习惯使用androidx，因此不能使用android.support.v7，所以尝试使用：

<androidx.recyclerview.widget.RecyclerView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/recyclerView"/>

代替

<android.support.v7.widget.RecyclerView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/recyclerView"/>

收到错误“ android.view.InflateException：膨胀类android.support.v7.widget.RecyclerView时出错”
