引用方式 compile 'com.bean.list_grid_view:adapter:1.0.0'

通用 viewholder的 CommonAdapter 使用

1、准备数据：编写 JavaBean，必须实现 Serializable 接口。

package com.adapter.smart.bean;
import java.io.Serializable;
import java.util.List;
/**
 * Created by smart on 2017/4/24.
 */

public class MoocBean implements Serializable {
    private int status;
    private String msg;
    private List<DataBean> data;

    public int getStatus() {
        return status;
    }

    public void setStatus(int status) {
        this.status = status;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public List<DataBean> getData() {
        return data;
    }

    public void setData(List<DataBean> data) {
        this.data = data;
    }

    public static class DataBean implements Serializable {

        private int id;
        private String name;
        private String picSmall;
        private String picBig;
        private String description;
        private int learner;

        public int getId() {
            return id;
        }

        public void setId(int id) {
            this.id = id;
        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public String getPicSmall() {
            return picSmall;
        }

        public void setPicSmall(String picSmall) {
            this.picSmall = picSmall;
        }

        public String getPicBig() {
            return picBig;
        }

        public void setPicBig(String picBig) {
            this.picBig = picBig;
        }

        public String getDescription() {
            return description;
        }

        public void setDescription(String description) {
            this.description = description;
        }

        public int getLearner() {
            return learner;
        }

        public void setLearner(int learner) {
            this.learner = learner;
        }
    }
}

2、自定义viewholder，这一步跟你用传统的方式是一样的，里面封装了 item 控件的引用；但是，要实现 IViewHolder 接口。

package com.adapter.smart.viewholder;

import android.widget.ImageView;
import android.widget.TextView;

import com.smart.holder_library.iinterface.IViewHolder;


/**
 * Created by smart on 2017/4/25.
 */

public class ListDataViewHolder implements IViewHolder {
    public TextView name;
    public TextView description;
    public TextView learner;
    public ImageView picSmall;
}

3、自定义 ViewHolderHelper， 传递一个List对象,IViewHolderHelper< VH，BEAN >，来实现 viewholder的实例化和数据绑定。

参数说明：

T ，也就是你自定义的自定义viewholder；

B ，也就是实现序列化接口的实体类；

package com.adapter.smart.viewholder;

import android.content.Context;
import android.support.annotation.NonNull;
import android.view.View;

import com.adapter.smart.R;
import com.adapter.smart.bean.MoocBean;
import com.adapter.smart.utils.UtilImageloader;
import com.smart.holder_library.iinterface.IViewHolder;
import com.smart.holder_library.iinterface.IViewHolderHelper;
import com.adapter.smart.utils.UtilWidget;

import java.util.List;

/**
 * Created by smart on 2017/4/26.
 */

/*
* 实例化你的viewholder
* 将数据和viewholder的控件绑定
* */
public class ListDataViewHolderHelper implements IViewHolderHelper<ListDataViewHolder,MoocBean.DataBean> {

    @Override
    public IViewHolder initItemViewHolder(ListDataViewHolder viewHolder, @NonNull View convertView) {
        viewHolder = new ListDataViewHolder();

        viewHolder.name = UtilWidget.getView(convertView, R.id.id_name);
        viewHolder.description = UtilWidget.getView(convertView,R.id.id_description);
        viewHolder.learner = UtilWidget.getView(convertView,R.id.id_learner);
        viewHolder.picSmall = UtilWidget.getView(convertView,R.id.id_picSmall);

        return viewHolder;
    }

    @Override
    public void bindListDataToView(Context context, List<MoocBean.DataBean> iBaseBeanList, ListDataViewHolder viewHolder, int position) {
        viewHolder.name.setText(iBaseBeanList.get(position).getName());//这个地方自己可以优化的，不必要每次获取list
        viewHolder.description.setText(iBaseBeanList.get(position).getDescription());
        viewHolder.learner.setText("人数："+iBaseBeanList.get(position).getLearner());
        UtilImageloader.setImage(context,iBaseBeanList.get(position).getPicSmall(),viewHolder.picSmall);
    }
}

4、配置适配器

4.1、函数说明

/**
 * param context 上下文
 * param iBaseBeanList 数据集（list的形式传递过来）
 * param itemViewLayout （item的布局文件）
 * param iViewHolderHelper （viewholder的接口）
 */
public CommonAdapter(Context context, List<BEAN> iBaseBeanList, int itemViewLayout, IViewHolderHelper iViewHolderHelper) {}

4.2、使用

mListView.setAdapter(new CommonAdapter(mContext, mDataBeanList, R.layout.list_view_item,new ListDataViewHolderHelper()));
