Adapter就是适配器，而设计模式里也有Adapter Pattern。

而BaseAdapter就是设计模式里的思维，把一些不相关的东西放进去，经过适配器，最终都会出产同一样的东西。

就像BaseAdapter，就算放不同的XML和Data进去，最终出现都是ListView的Cell。

 

1. BaseAdaper代码，完全没有特别的地方，不解述了。

package com.paradise.electronic.eparadise2.adapter;import android.content.Context;import android.graphics.Bitmap;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.ImageView;import android.widget.TextView;import com.paradise.electronic.eparadise2.R;import com.paradise.electronic.eparadise2.dto.PostDTO;import java.util.List;/** * Created by Administrator on 17-11-12. */public class PostAdapter extends BaseAdapter {    // data    private Context context;    private LayoutInflater inflter;    private List
        
          postDTOs;    private List
         
           bitMaps;    // UI    private TextView tvPostTitle;    private TextView tvPostDate;    private ImageView imgAbstractImg;    public PostAdapter(Context context, List
          
            postDTOs, List
           
             bitMaps) {        super();        this.postDTOs = postDTOs;        this.bitMaps = bitMaps;        this.context = context;        inflter = (LayoutInflater.from(context));    }    @Override    public int getCount() {        return postDTOs.size();    }    @Override    public Object getItem(int position) {        return null;    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        // 初始化convertView        convertView = inflter.inflate(R.layout.lv_home_post, null);        // 初始化UI        tvPostTitle = (TextView) convertView.findViewById(R.id.tvPostTitle);        tvPostDate = (TextView) convertView.findViewById(R.id.tvPostDate);        imgAbstractImg = (ImageView) convertView.findViewById(R.id.imgAbstractImg);        // Set date into tv        tvPostTitle.setText(postDTOs.get(position).getTitle());        tvPostDate.setText(postDTOs.get(position).getDate());        imgAbstractImg.setImageBitmap(bitMaps.get(position));        return convertView;    }}
           
          
         
        

2. 初始化BaseAdaper，然后让ListView调用BaseAdaper就可以。

private String strJsPost;    private void initData() {        // set view unclickable first        rlFragmentHome.setClickable(false);        // Network thread        new Thread(new Runnable() {            @Override            public void run() {                // get 
        
         post from network                strJsPost = okhttp.getResponse(Configuration.getHotPost);                postHotDTOs = gsonTools.getPost(strJsPost);                // get post image URL from network, than convect the file to bitmap                bitHotMaps = new ArrayList
         
          ();                for (int i = 0; i < postHotDTOs.size(); i++ ) {                    Bitmap temp = bitMap.returnBitMap(postHotDTOs.get(i).getAbstractImg());                    bitHotMaps.add(temp);                }                // UI thread                getActivity().runOnUiThread(new Runnable() {                    @Override                    public void run() {                        // init adapter                        postAdapter = new PostAdapter(getActivity(), postHotDTOs, bitHotMaps);                        lvHomePostItem.setAdapter(postAdapter);                        // hide loading textview                        tvHomeLoading.setText("");                        tvHomeLoading.getLayoutParams().height = 0;                        // set view unclickable while finishing                        rlFragmentHome.setClickable(true);                    }                });            }        }).start();    }
