一，项目介绍
首先看项目流程（接口都写在model类中，不提出来一一写了）
二，项目思路分析
可以看出框架为MVP，主要思路是：1，MD5加密的登录注册。2，登陆成功后跳转到RecyclerView+网络请求（Okhttp+Retrofit+Rxjava）+Fresco显示图片实现的商品列表。3，点击列表条目跳转到详情页面。4，点击详情页面中的添加购物车，提示加购成功，点击购物车，商家和商品信息显示在购物车页面进行操作。5，购物车，使用RecyclerView实现。6，点击结算，跳转到订单页面，订单页面使用radioGroup+viewPage+Fragment。
三，项目框架预览
用到的依赖
compile 'com.facebook.fresco:fresco:0.9.0+' compile 'com.android.support:recyclerview-v7:26.1.0' compile 'com.jakewharton:butterknife:8.8.1' annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1' compile 'com.squareup.okhttp3:okhttp:3.9.1'//OkHttp依赖 compile 'com.android.support:recyclerview-v7:26.1.0'//RecyclerView依赖 compile 'com.liaoinstan.springview:library:1.3.0'//SpringView依赖 compile 'com.github.bumptech.glide:glide:4.3.1' //glide加载图片 compile 'com.squareup.okhttp3:logging-interceptor:3.9.0' //双击查看原图http拦截器 compile 'com.google.code.gson:gson:2.8.2' //gson依赖 compile 'com.squareup.retrofit2:retrofit:2.3.0' compile 'com.squareup.retrofit2:converter-gson:2.3.0' compile 'io.reactivex.rxjava2:rxjava:2.1.7' compile 'com.facebook.fresco:fresco:1.7.1' compile 'com.jakewharton:butterknife:8.2.1' compile 'com.squareup.retrofit2:adapter-rxjava2:2.3.0' compile 'io.reactivex.rxjava2:rxandroid:2.0.1' compile 'com.squareup.retrofit2:converter-scalars:2.3.0' compile 'com.jakewharton:butterknife:8.8.1' annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
四，首先开始完成登录注册
准备工作：（1）：配置Fresco图片显示，app包下创建一个类
public class MyApp extends Application{ @Override public void onCreate() { super.onCreate(); //配置 Fresco.initialize(this); } }然后到清单文件中，配置并且配置网络权限
<uses-permission android:name="android.permission.INTERNET" /> <application android:name=".app.MyApp" android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme">准备工作：（2）：网络数据请求OKhttp+Retrofit+Rxjava封装，在retrofit包中分为三个类
public interface ApiService { @GET Observable<String> get(@Url String url, @QueryMap Map<String, String> map); @FormUrlEncoded @POST Observable<String> post(@Url String url, @FieldMap Map<String, String> map); }
public abstract class BaseObserver<T> implements Observer<String> { @Override public void onSubscribe(Disposable d) { } @Override public void onNext(String s) { try { Type genType = getClass().getGenericSuperclass(); Type[] params = ((ParameterizedType) genType).getActualTypeArguments(); Class entityClass = (Class) params[0]; Gson gson = new Gson(); T t = (T)gson.fromJson(s,entityClass); success(t); } catch (Exception e) { failure(1001); e.printStackTrace(); } } @Override public void onError(Throwable e) { try { if(e != null){ if(e instanceof HttpException){ failure(HTTP_ERROR); } else if(e instanceof SocketException){ failure(NET_WORK_ERROR); }else { failure(UNKNOW_ERROR); } }else { failure(UNKNOW_ERROR); } e.printStackTrace() ; } catch (Exception e1) { failure(UNKNOW_ERROR); e1.printStackTrace(); } } @Override public void onComplete() { } // /** * code * 1000 UNKNOW_ERROR 未知错误 * 1001 json 转化异常 parse error * 1002 当前网络不可用 java.net.SocketException: Network is unreachable 超时 * 1003 服务器不可用 401 402 403 500 502 503 504 * @param code */ public static final int UNKNOW_ERROR = 1000; public static final int JSON_FORMAT_ERROR = 1001; public static final int NET_WORK_ERROR = 1002; public static final int HTTP_ERROR = 1003; public abstract void success(T t); public abstract void failure(int code); public abstract void onNext(LoginBean loginBean); public abstract void onNext(RegBean regBean); }
public class RetrofitManager { public static OkHttpClient client = new OkHttpClient.Builder() //添加拦截器 .addInterceptor(new MyInterceptor()) .build(); public static ApiService apiService = new Retrofit.Builder() .baseUrl("http://120.27.23.105/") .addCallAdapterFactory(RxJava2CallAdapterFactory.create()) .addConverterFactory(ScalarsConverterFactory.create()) .client(client) .build() .create(ApiService.class); public static void get(String url, Map<String,String> map,Observer observer){ apiService.get(url,map) .subscribeOn(Schedulers.io()) .observeOn(AndroidSchedulers.mainThread()) .subscribe(observer); } public static void post(String url,Map<String,String> map,Observer observer){ apiService.post(url,map) .subscribeOn(Schedulers.io()) .observeOn(AndroidSchedulers.mainThread()) .subscribe(observer); } }如果接口需要上传公共参数，那么写一个拦截器类然后在retrofitmanneger类中如果添加拦截器即可（看注释）
拦截器
public class MyInterceptor implements Interceptor { @Override public Response intercept(Chain chain) throws IOException { Request request = chain.request(); String string = request.url().url().toString(); String s = string + "&source=android"; Request request1 = request.newBuilder().url(s).build(); Response response = chain.proceed(request1); return response; } }
好了，现在开始进行项目编辑
1，登录页面布局
activity_main
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <EditText android:id="@+id/phone" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="50dp" android:gravity="center" android:hint="请输入手机号" /> <EditText android:id="@+id/password" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="50dp" android:gravity="center" android:hint="请输入密码" /> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="50dp" android:gravity="center" android:orientation="horizontal"> <Button android:id="@+id/login" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:text="登录" /> <Button android:id="@+id/reg" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:text="注册" /> </LinearLayout> </LinearLayout>2，注册页面布局 activity_reg.xml

七，购物车，购物车使用了自定义控件
1，自定义控件布局和实现类
自定义控件布局custom.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="match_parent"> <Button android:id="@+id/custom_jian" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="-"/> <EditText android:id="@+id/count_edtext" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="1"/> <Button android:id="@+id/custom_add" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="+"/> </LinearLayout>
2，自定义控件实现类
public class CustomView extends LinearLayout { //定义输入框的默认值 int mcount = 1; Button customJian; EditText countEdtext; Button customAdd; public CustomView(Context context) { super(context); } public CustomView(Context context, @Nullable AttributeSet attrs) { super(context, attrs); View view = View.inflate(context, R.layout.custom, null); //找到控件 customJian = view.findViewById(R.id.custom_jian); countEdtext = view.findViewById(R.id.count_edtext); customAdd = view.findViewById(R.id.custom_add); //减号的点击事件 customJian.setOnClickListener(new OnClickListener() { @Override public void onClick(View view) { //点击之前先拿到输入框里的值 String string = countEdtext.getText().toString().trim(); //转化数据类型 int count = Integer.valueOf(string); //如果输入框的数据大于1，点击减号的时候，就让其减少一 if (count>1){ mcount = count-1; countEdtext.setText(mcount+""); } //接口回调 if (jiaJian!=null){ jiaJian.dianji(mcount); } } }); //加号的点击事件 customAdd.setOnClickListener(new OnClickListener() { @Override public void onClick(View view) { //点击之前先拿到输入框里的值 String string = countEdtext.getText().toString().trim(); //转化数据类型 int count = Integer.valueOf(string)+1; //如果输入框的数据大于1，点击减号的时候，就让其减少一 mcount = count; countEdtext.setText(mcount+""); //接口回调 if (jiaJian!=null){ jiaJian.dianji(mcount); } } }); //中间输入框内的变化 countEdtext.addTextChangedListener(new TextWatcher() { @Override public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) { } @Override public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) { } @Override public void afterTextChanged(Editable editable) { } }); addView(view); } public CustomView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } //给输入框赋值的方法 public void setEditText(int num){ if(countEdtext != null){ countEdtext.setText(num+""); } } //加减号的点击事件接口 JiaJian jiaJian; public void setJiaJian(JiaJian jiaJian) { this.jiaJian = jiaJian; } public interface JiaJian{ public void dianji(int count); } }
