Adapt

繼承RecyclerView.Adapter的子類，顯示資料集項目的視圖。

public class Adapter extends RecyclerView.Adapter<RecyclerListAdapter.ItemViewHolder>

繼承RecyclerView.ViewHolder的子類容器。

public static class ItemViewHolder extends RecyclerView.ViewHolder implements ItemTouchHelperViewHolder {

         public final TextView mTextView ;

         public ItemViewHolder(View itemView) {
                super(itemView);
                mTextView = (TextView) itemView.findViewById(R.id.textview);
            }
}

初始化項目視圖。

@Override
public ItemViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item, parent, false);
            ItemViewHolder itemViewHolder = new ItemViewHolder(view);
            return itemViewHolder;
}

給定項目內容。

@Override
public void onBindViewHolder(final ItemViewHolder holder, int position) {
                holder.mTextView.setText(mItems.get(position));
//recyclerview 沒有OnItemClickListener需要自己添加
                holder.mTextView.setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    if (MotionEventCompat.getActionMasked(event) == MotionEvent.ACTION_DOWN) {
                        mOnTouchListener.onClcikEvent();
                    }
                    return false;
                }
            });
}
public interface OnTouchListener {

    void onClcikEvent();
}
public void setOnTouchListener (OnTouchListener onTouchListener ){
    this.mOnTouchListener = onTouchListener ;
}
