自定義RecyclerView適配器

package com.example.demo.recyclerviewtest;import android.support.v7.widget.RecyclerView; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TextView;import java.util.ArrayList;public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder>{private ArrayList<String> contentList;public MyAdapter(ArrayList<String> contentList){this.contentList = contentList;}@Overridepublic MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {ViewHolder viewHolder = new ViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.item_content,parent,false));return viewHolder;}@Overridepublic void onBindViewHolder(MyAdapter.ViewHolder holder, int position) {holder.textView.setText(contentList.get(position));}@Overridepublic int getItemCount() {return contentList.size();}public class ViewHolder extends RecyclerView.ViewHolder {private TextView textView;public ViewHolder(View view) {super(view);textView = (TextView) view.findViewById(R.id.text_view);}}}

Activity
