其实适配器还是蛮常用的，最近在写健康管家，实现一个医生列表用到了一个比较复杂的带两个点击事件的适配器i，因为我的android studio他实在是要卡死了，所以我很在很痛苦的等待，顺便来做个总结。我等的好痛苦，为什么as运行一下gradle building要那么久，崩溃！！

要填充一个漂亮的数组，首先需要一个容器listview+和一个装在容器里面的item的样式（adapter）.

效果图

(为什么这个图片上传有问题哇)

一、有按钮点击功能的适配器

• DoctorListActivity.java   （显示列表）

这个java类的主界面包含了一个填充容器list（xml代码很简单就不贴了），继承ListItemClickHelp是为了实现列表中每一行的按钮点击事件

public class DoctorListActivity  extends Activity  implements ListItemClickHelp{

private static final String results = "{\n" +
"  \"error\": false,\n" +
"  \"results\": [\n" +

二、不带有点击功能适配器

不带有按钮点击功能适配器与带点击功能的适配器不同的就是，用于显示的主函数.java文件不需要继承接口，适配器有所不同，这里就贴一份适配器的代码，思路都是一样的，需要用的时候稍加修改就可以了。

package com.mialab.healthbutler.adapter;

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

import com.mialab.healthbutler.R;
import com.mialab.healthbutler.domain.Illness;

import java.util.List;

import butterknife.BindView;
import butterknife.ButterKnife;

/**
* Created by hp on 2016/6/10.
*/
public class IllnessAdapter extends BaseAdapter {

private Context context;
private List<Illness> Illnessses;

public IllnessAdapter(Context context, List<Illness> Illnessses) {
this.context = context;
this.Illnessses = Illnessses;
}

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

@Override
public Illness getItem(int position) {
return Illnessses.get(position);
}

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

@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView != null) {
holder = (ViewHolder) convertView.getTag();
} else {
convertView = View.inflate(context, R.layout.list_illness_item, null);
holder = new ViewHolder(convertView);
convertView.setTag(holder);
}
holder.tvName.setText(getItem(position).getIllness_name());
return convertView;
}

static final class ViewHolder {
@BindView(R.id.tv_name)
TextView tvName;

public ViewHolder(View view) {
ButterKnife.bind(this, view);
}
}
}
