定义一个CommonViewHolder类

public abstract class CommonViewHolder<T>{
    //实现实例化控件
    public abstract void initView(View view);
    //实现对控件进行填充内容
    public abstract void updateView(int pos, T item);
}

定义一个CommonAdapter类：

public abstract class CommonAdapter<T> extends BaseAdapter{

    protected Context mContext;
    protected List<T> mList;

    /**
     * 构造函数传入上下文和数据
     * @param mContext
     * @param mList
     */
    public CommonAdapter(Context mContext, List<T> mList) {
        this.mContext = mContext;
        this.mList = mList;
    }

    @Override
    public int getCount() {
        return mList.size();
    }

    @Override
    public Object getItem(int position) {
        return mList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }


    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        //定义holder对象
        CommonViewHolder holder;
        if (convertView == null){
            //解析布局文件为view
            convertView = LayoutInflater.from(mContext).inflate(getLayout(), parent,false);
            //创建holder对象
            holder = createViewHolder();
            //初始化控件
            holder.initView(convertView);
            //保存holder对象
            convertView.setTag(holder);
        } else {
            holder = (CommonViewHolder) convertView.getTag();
        }
        //更新控件中的内容
        holder.updateView(position, getItem(position));
        return convertView;
    }

    //交给子类实现创建holder对象
    protected abstract CommonViewHolder createViewHolder();
    //交给子类获取到布局文件
    protected abstract int getLayout();
}

具体实现类：

public class MyWordAdapter extends CommonAdapter<WordBean> {
    public MyWordAdapter(Context mContext, List<WordBean> mList) {
        super(mContext, mList);
    }

    //实现创建viewHolder对象
    @Override
    protected CommonViewHolder createViewHolder() {
        return new ViewHolder();
    }

    //返回布局文件
    @Override
    protected int getLayout() {
        return R.layout.my_word_layout;
    }

    //继承CommonViewHolder，实现具体的初始化工作和更新UI
    private class ViewHolder extends CommonViewHolder<WordBean>{
        private TextView text_key;
        private TextView text_value;

        @Override
        public void initView(View view) {
            text_key = (TextView) view.findViewById(R.id.id_text_word_layout_key);
            text_value = (TextView) view.findViewById(R.id.id_text_word_layout_value);
        }

        @Override
        public void updateView(int pos, WordBean item) {
            text_key.setText(item.getKey());
            text_value.setText(item.getValue());
        }
    }

}
