在网上的视频看到的一个很好用的自定义BaseAdapter，自己修改了一下后一直在用，分享给大家，这样的话绑定gridView或listView就方便多了，直接在adapter里面初始化数据源，十分的方便，希望对大家有用，有可以改进的地方大家一起讨论

在自定义的BaseAdapter中绑定数据源，数据源为泛型

代码：

文件名：McxBaseAdapter.java

import java.util.ArrayList;import java.util.List;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;/** * Adapter基本类 * * @project NewSilkRoad * @author MCX * @date -4- * @time 下午2:: * @param <T> */public abstract class McxBaseAdapter<T> extends BaseAdapter {public McxBaseAdapter(Context context, int resid) {this.context = context;listCellId = resid;}private Context context;private int listCellId = 0;public Context getContext() {return context;}// 数据源private List<T> myList = new ArrayList<T>();public void add(T item) {myList.add(item);}public void remove(int position) {myList.remove(position);}public void removeLast() {remove(myList.size() - 1);}@Overridepublic int getCount() {return myList.size();}@Overridepublic T getItem(int position) {return myList.get(position);}@Overridepublic long getItemId(int position) {return position;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {if (convertView == null) {convertView = LayoutInflater.from(getContext()).inflate(listCellId,null);}initListCell(position, convertView, parent);return convertView;}protected abstract void initListCell(int position, View listCell,ViewGroup parent);}

使用方法：

activity中：

private GridView gv_group_tour;

private McxBaseAdapter<GroupTour> adapter; //GroupTour为自定义的数据类型

@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);

setContentView(R.layout.activity_group_tour);initView();//初始化方法initEvent();//初始化事件}

private void initEvent() {//绑定adaptergv_group_tour.setAdapter(adapter);//添加数据，根据自定义的model添加数据，也可改成解析后的数据源，然后进行匹配即可adapter.add(new GroupTour("aa", "bb", "", "","--至-", R.drawable.im_ztydatu1,R.drawable.btn_segeren));

}

private void initView() {gv_group_tour = (GridView) findViewById(R.id.gv_group_tour);//初始化自定义的McxBaseAdapter，R.layout.activity_group_tour_gv_cell为gridview的item样式adapter = new McxBaseAdapter<GroupTour>(GroupTourActivity.this,R.layout.activity_group_tour_gv_cell) {@Overrideprotected void initListCell(int position, View listCell,ViewGroup parent) {

//初始化数据源GroupTour data = getItem(position);//初始化activity_group_tour_gv_cell中的控件，并从数据源中添加数据，下面同理LinearLayout ly_img = (LinearLayout) listCell.findViewById(R.id.ly_group_tour_img);ly_img.setBackgroundResource(data.getImg());ImageView img_head = (ImageView) listCell.findViewById(R.id.img_group_tour_headimg);img_head.setBackgroundResource(data.getHeadimg());TextView tv_title = (TextView) listCell.findViewById(R.id.tv_group_tour_title);tv_title.setText(data.getTitle());TextView tv_username = (TextView) listCell.findViewById(R.id.tv_group_tour_username);tv_username.setText(data.getUsername());TextView tv_number = (TextView) listCell.findViewById(R.id.tv_group_tour_number);tv_number.setText(data.getNumber());TextView tv_money = (TextView) listCell.findViewById(R.id.tv_group_tour_money);tv_money.setText(data.getMoney());TextView tv_time = (TextView) listCell.findViewById(R.id.tv_group_tour_time);tv_time.setText(data.getTime());}};}

自定义的model：

文件名：GroupTour.java

public class GroupTour {public GroupTour(String title, String username, String number,String money, String time, int img, int headimg) {this.title = title;this.username = username;this.number = number;this.money = money;this.time = time;this.img = img;this.headimg = headimg;}private String title;private String username;private String number;private String money;private String time;private int img;private int headimg;public int getHeadimg() {return headimg;}public void setHeadimg(int headimg) {this.headimg = headimg;}public String getTitle() {return title;}public void setTitle(String title) {this.title = title;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getNumber() {return number;}public void setNumber(String number) {this.number = number;}public String getMoney() {return money;}public void setMoney(String money) {this.money = money;}public String getTime() {return time;}public void setTime(String time) {this.time = time;}public int getImg() {return img;}public void setImg(int img) {this.img = img;}}
