}
class GroupHolder{

AddSubLayout addSub;
}
}
四、adapter用到的两个布局及背景
1、group布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:orientation="horizontal"
xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
android:layout_height="match_parent">
<CheckBox
android:id="@+id/checkBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:focusable="false"
android:text="酸辣粉"/>
</LinearLayout>
2、child布局
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:background="@drawable/search_edit_bg"
android:orientation="horizontal">
<CheckBox
android:id="@+id/cart_goods_check"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"/>
<ImageView
android:id="@+id/image"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:minHeight="50dp"
android:layout_toRightOf="@+id/cart_goods_check"
android:src="@mipmap/ic_launcher"/>
<TextView
android:id="@+id/text"
android:layout_toRightOf="@+id/image"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="aa"
android:padding="10dp"/>
<TextView
android:id="@+id/text_price"
android:layout_toRightOf="@+id/image"
android:layout_below="@+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="价格"
android:padding="10dp"/>
<gj.com.month_buycar.view.AddSubLayout
android:id="@+id/add_sub_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:layout_marginRight="40dp"
android:layout_marginBottom="40dp"></gj.com.month_buycar.view.AddSubLayout>
</RelativeLayout>
背景① search_edit_bg：
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<!--设置圆角边框及颜色-->
<corners android:radius="20dp"/>
<solid
android:color="#d8d8d8"/>
</shape>
五、适配器用到的GJApplication(记得在清单文件中注册)
application下：android:name=".core.GJApplication"
package gj.com.buycar.core;
import android.app.Application;
import android.content.Context;
import android.content.SharedPreferences;
public class GJApplication extends Application {
private static GJApplication instance;
private SharedPreferences mSharedPreferences;
@Override
public void onCreate() {
super.onCreate();
instance = this;
mSharedPreferences = getSharedPreferences("application",
Context.MODE_PRIVATE);
}
public static GJApplication getInstance() {
return instance;
}
public SharedPreferences getShare() {
return mSharedPreferences;
}
}
六、适配器用到的AddSubLayout
package gj.com.buycar.view;
import android.content.Context;
import android.os.Build;
import android.support.annotation.RequiresApi;
import android.util.AttributeSet;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.widget.Toast;
import gj.com.buycar.R;
public class AddSubLayout extends LinearLayout implements View.OnClickListener {
private TextView mAddBtn;
private TextView mSubBtn;
private TextView mNumText;
public AddSubLayout(Context context) {
super(context);
initView();
}
public AddSubLayout(Context context, AttributeSet attrs) {
super(context, attrs);
initView();
}
public AddSubLayout(Context context,AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
initView();
}
@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
public AddSubLayout(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
initView();
}
//创建布局视图
private void initView() {
//加载layout布局，第三个参数ViewGroup一定写成this
View view = View.inflate(getContext(),
R.layout.car_add_sub_layout,this);
//初始化组件
mAddBtn = view.findViewById(R.id.btn_add);
mSubBtn = view.findViewById(R.id.btn_sub);
mNumText = view.findViewById(R.id.text_number);
//设置加减的点击事件
mAddBtn.setOnClickListener(this);
mSubBtn.setOnClickListener(this);
}
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
super.onLayout(changed, l, t, r, b);
int width = r-1;//getWidth();
int hright = b-t;//getHeight();
}
@Override
public void onClick(View v) {
//得到数量的值
int number = Integer.parseInt(mNumText.getText().toString());
switch (v.getId()){
case R.id.btn_add:
number++;
mNumText.setText(number+"");//赋值
break;
case R.id.btn_sub:
if(number==0){
Toast.makeText(getContext(),"数量不能小于0",Toast.LENGTH_LONG).show();
return;
}
number--;
mNumText.setText(number+"");//赋值
break;
}
if(addSubLinstener!=null){
addSubLinstener.addSub(number);
}
}
public void setCount(int count){
mNumText.setText(count+"");
}
AddSubLinstener addSubLinstener;
public void setAddSubLinstener(AddSubLinstener addSubLinstener) {
this.addSubLinstener = addSubLinstener;
}
public interface AddSubLinstener{
void addSub(int count);
}
}
七、AddSubLayout加减框用到的布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:orientation="horizontal"
xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
android:layout_height="match_parent">
<!--加减框-->
<TextView
android:id="@+id/btn_add"
android:layout_width="30dp"
android:layout_height="30dp"
android:background="@drawable/car_btn_bg"
android:focusable="false"
android:textSize="16sp"
android:gravity="center"
android:text="+"/>
<TextView
android:id="@+id/text_number"
android:layout_width="60dp"
android:layout_height="30dp"
android:gravity="center"
android:textSize="14sp"
android:text="10" />
<TextView
android:id="@+id/btn_sub"
android:layout_width="30dp"
android:layout_height="30dp"
android:textSize="16sp"
android:focusable="false"
android:gravity="center"
android:background="@drawable/car_btn_bg"
android:text="-" />
</LinearLayout>
八、加减框用到的背景设置car_btn_bg
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<!--加减框的圆角边框-->
<corners
android:radius="5dp"></corners>
<!--边框颜色-->
<stroke
android:color="@android:color/holo_red_dark"
android:width="2dp"></stroke>
</shape>
九、接口
package gj.com.buycar.core;
import gj.com.month_buycar.bean.Result;
public interface DataCall<T> {
void success(T data);
void fail(Result result);
}
十、三个Bean类
①result
package gj.com.buycar.bean;
import java.util.List;
public class Result<T> {
private int code;
private String msg;
private T data;
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
public int getCode() {
return code;
}
public void setCode(int code) {
this.code = code;
}
public T getData() {
return data;
}
public void setData(T data) {
this.data = data;
}
}
②Shop
package gj.com.buycar.bean;
import java.util.List;
import gj.com.buycar.R;
public class Shop {
/**
* list : []
* sellerName :
* sellerid : 0
*/
//商品的bean 多写了三个东西 商品字体颜色 背景 选中状态
private List<Goods> list;
private String sellerName;
private String sellerid;
int textColor = 0xffffffff;
int background = R.color.grayblack;
boolean check;
public String getSellerName() {
return sellerName;
}
public void setSellerName(String sellerName) {
this.sellerName = sellerName;
}
public String getSellerid() {
return sellerid;
}
public void setSellerid(String sellerid) {
this.sellerid = sellerid;
}
public List<Goods> getList() {
return list;
}
public void setList(List<Goods> list) {
this.list = list;
}
public int getTextColor() {
return textColor;
}
public void setTextColor(int textColor) {
this.textColor = textColor;
}
public int getBackground() {
return background;
}
public void setBackground(int background) {
this.background = background;
}
public boolean isCheck() {
return check;
}
public void setCheck(boolean check) {
this.check = check;
}
}
③Goods
package gj.com.buycar.bean;
import java.io.Serializable;
public class Goods implements Serializable {
private double bargainPrice;
private String createtime;
private String detailUrl;
private String images;
private int num;
private int pid;
private double price;
private int pscid;
private int selected;
private int sellerid;
private String subhead;
private String title;
private int count = 1;//多加了一个 商品的count
public int getCount() {
return count;
}
public void setCount(int count) {
this.count = count;
}
public double getBargainPrice() {
return bargainPrice;
}
public void setBargainPrice(double bargainPrice) {
this.bargainPrice = bargainPrice;
}
public String getCreatetime() {
return createtime;
}
public void setCreatetime(String createtime) {
this.createtime = createtime;
}
public String getDetailUrl() {
return detailUrl;
}
public void setDetailUrl(String detailUrl) {
this.detailUrl = detailUrl;
}
public String getImages() {
return images;
}
public void setImages(String images) {
this.images = images;
}
public int getNum() {
return num;
}
public void setNum(int num) {
this.num = num;
}
public int getPid() {
return pid;
}
public void setPid(int pid) {
this.pid = pid;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
public int getPscid() {
return pscid;
}
public void setPscid(int pscid) {
this.pscid = pscid;
}
public int getSelected() {
return selected;
}
public void setSelected(int selected) {
this.selected = selected;
}
public int getSellerid() {
return sellerid;
}
public void setSellerid(int sellerid) {
this.sellerid = sellerid;
}
public String getSubhead() {
return subhead;
}
public void setSubhead(String subhead) {
this.subhead = subhead;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
十一、model M层
package gj.com.buycar.model;
import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;
import java.lang.reflect.Type;
import java.util.List;
import gj.com.buycar.bean.Result;
import gj.com.buycar.bean.Shop;
import gj.com.buycar.utils.HttpUtils;
public class CartModel {
public static Result goodsList(){
String resultString = HttpUtils.get("http://www.zhaoapi.cn/product/getCarts?uid=71");
//try {
//注意了
Type type = new TypeToken<Result<List<Shop>>>(){}.getType();
Result result = new Gson().fromJson(resultString, type);
return result;
/*} catch (Exception e) {
}
Result result = new Result();
result.setCode(-1);
result.setMsg("数据解析异常");
return result;*/
}
}
十二、presentre P层
package gj.com.buycar.presenter;
import gj.com.buycar.bean.Result;
import gj.com.buycar.core.DataCall;
import gj.com.buycar.model.CartModel;
public class CartPresenter extends BasePresenter{
public CartPresenter(DataCall dataCall) {
super(dataCall);
}
@Override
protected Result getData(Object... args) {
//调用网络请求获取数据M层
Result result = CartModel.goodsList();
return result;
}
}
十三、BasePresenter层
package gj.com.buycar.presenter;
import android.os.Handler;
import android.os.Message;
import gj.com.buycar.bean.Result;
import gj.com.buycar.core.DataCall;
public abstract class BasePresenter {
//接口
DataCall dataCall;
public BasePresenter(DataCall dataCall) {
this.dataCall = dataCall;
}
Handler mHandler = new Handler(){
@Override
public void handleMessage(Message msg) {
Result result = (Result) msg.obj;
//判断是否成功
if(result.getCode()==0){
//将商铺信息传过去
dataCall.success(result.getData());
}else{
dataCall.fail(result);
}
}
};
//得到请求数据
public void requestData(final Object...args){
new Thread(new Runnable() {
@Override
public void run() {
Message message = mHandler.obtainMessage();
message.obj = getData(args);//定义一个抽象方法调用
mHandler.sendMessage(message);
}
}).start();
}
protected abstract Result getData(Object...args);
//避免内存溢出
public void unBindCall(){
this.dataCall = null;
}
}
十四、okHttp网络请求（根据需求 可不写）
package gj.com.buycar.utils;
import android.util.Log;
import java.io.File;
import java.io.IOException;

十五、okHttp请求日志
package gj.com.buycar.utils;

import okhttp3.ResponseBody;
/**
* 打印OKHTTP请求日志
*/
public class LoggingInterceptor implements Interceptor {
@Override
public Response intercept(Chain chain) throws IOException {
//这个chain里面包含了request和response，所以你要什么都可以从这里拿
Request request = chain.request();
long t1 = System.nanoTime();//请求发起的时间
Log.i("dt",String.format("发送请求 %s on %s%n%s",
request.url(), chain.connection(), request.headers()));
Response response = chain.proceed(request);
long t2 = System.nanoTime();//收到响应的时间
//这里不能直接使用response.body().string()的方式输出日志
//因为response.body().string()之后，response中的流会被关闭，程序会报错，我们需要创建出一
//个新的response给应用层处理
ResponseBody responseBody = response.peekBody(1024 * 1024);
Log.i("dt",String.format("接收响应: [%s] %n返回json:【%s】 %.1fms%n%s",
