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 2015-4-13
* @time 下午2:02:44
* @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);
}
@Override
public int getCount() {
return myList.size();
}
@Override
public T getItem(int position) {
return myList.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public 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
@Override
protected 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adapter
gv_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", "1000", "1000",
"9999-01-01至12-12", 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) {
@Override
protected 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;
}
}
