本文详细介绍了一个基于MVP架构的购物车功能实现方案，包括主Activity、View层接口、Model层接口及其实现类、Presenter层类等核心组件的设计与代码实现。
主Activity
//实现view层的接口 并且重写接口的方法 public class MainActivity extends AppCompatActivity implements MainViewListener { RecyclerView third_recyclerview; LinearLayout third_pay_linear; CheckBox third_allselect; Button third_submit; TextView edittext, third_totalnum, third_totalprice; private MainPresenter presenter; private ShopAdapter adapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); third_recyclerview = (RecyclerView) findViewById(R.id.third_recyclerview); third_pay_linear = (LinearLayout) findViewById(R.id.third_pay_linear); third_allselect = (CheckBox) findViewById(R.id.third_allselect); third_totalprice = (TextView) findViewById(R.id.third_totalprice); edittext = (TextView) findViewById(R.id.edittext); third_totalnum = (TextView) findViewById(R.id.third_totalnum); third_submit = (Button) findViewById(R.id.third_submit); presenter = new MainPresenter(this); presenter.getData(); adapter = new ShopAdapter(this); LinearLayoutManager manager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false); third_recyclerview.setLayoutManager(manager); third_recyclerview.setAdapter(adapter); third_allselect.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { adapter.selectAll(third_allselect.isChecked()); } }); adapter.setListener(new ShopAdapter.UpdateUiListener() { @Override public void setTotal(String total, String num, boolean allCheck) { third_allselect.setChecked(allCheck); third_totalnum.setText(num); third_totalprice.setText(total); } }); third_submit.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Intent intent = new Intent(MainActivity.this, WeiXin.class); startActivity(intent); } }); } @Override public void succer(ShopBean bean) { adapter.add(bean); } @Override public void Defeat(Exception e) { Toast.makeText(this, "error", Toast.LENGTH_SHORT).show(); } @Override protected void onDestroy() { super.onDestroy(); presenter.detach(); } }主布局文件

public interface MainViewListener { void succer(ShopBean bean);//成功的方法 void Defeat(Exception e);//失败的方法 }modle层
nodle的类
public class MainModel { //获取网路数据 传入Modle的接口 public void getData(final MainModelCallBack callBack) { OkhttpUtils.getInstance().asy(null, "http://120.27.23.105/product/getCarts?uid=100", new AbstractUiCallBack<ShopBean>() { @Override public void success(ShopBean shopBean) { //这里用接口的的对象去调用接口的方法 callBack.succer(shopBean); } @Override public void failure(Exception e) { //这里用接口的的对象去调用接口的方法 callBack.Defeat(e); } }); } }modle的接口
public interface MainModelCallBack { void succer(ShopBean bean);//成功的方法 void Defeat(Exception e);//失败的方法 }presenter层
public class MainPresenter { //初始化 Modle层的类 和View层的接口 MainModel mainModel; //modle的类 MainViewListener mainViewListener;//View层的接口 //给有参构造 只给接口 不给Modle层 public MainPresenter(MainViewListener mainViewListener) { this.mainViewListener = mainViewListener; this.mainModel = new MainModel(); } //获取参数 New出来Modle层的接口 public void getData() { mainModel.getData(new MainModelCallBack() { @Override public void succer(ShopBean bean) { //判断数据是否请求成功 请求成功的了 // 就调取成功的方法 否则就是失败 那就调取失败的方法 if (mainViewListener != null) {//这是成功的方法 mainViewListener.succer(bean); } } @Override public void Defeat(Exception e) {//这是失败的方法 if (mainViewListener != null) { mainViewListener.Defeat(e); } } }); } /** * 防止内存泄漏 */ public void detach() { mainViewListener = null; } }下面是购物车的自定义View用于加减号

我这里用的是Imageloade需要配置文件下面是我的配置文件
/** * 这是配置ImageLoage的 配置完要在清单文件中注册 */ public class MyApps extends Application { @Override public void onCreate() { super.onCreate(); File file = new File(Environment.getExternalStorageDirectory().getPath()+"Images0718"); ImageLoaderConfiguration conn = new ImageLoaderConfiguration.Builder(this) .threadPoolSize(5) .memoryCacheExtraOptions(80, 80) .memoryCacheSize(2 * 1024 * 1024) .threadPriority(1000) .diskCacheFileNameGenerator(new Md5FileNameGenerator()) .diskCacheSize(50 * 1024 * 1024) .build(); ImageLoader.getInstance().init(conn); } }我用的是OkHttp请求下面是我封装的OkHttp
//Okhttp 单例 范型的封装 public abstract class AbstractUiCallBack<T> implements Callback { /** * 成功回调 * @param t */ public abstract void success(T t); /** * 失败回调 * @param e */ public abstract void failure(Exception e); private Handler handler = null ; private Class clazz ; public AbstractUiCallBack(){ handler = new Handler(Looper.getMainLooper()); // 得到的是一个 AbstractUiCallBack<T> 的Type Type type = getClass().getGenericSuperclass() ; // 得到的是T的实际Type Type [] arr = ((ParameterizedType)type).getActualTypeArguments() ; clazz = (Class) arr[0] ; } @Override public void onFailure(Call call, IOException e) { failure(e); } @Override public void onResponse(Call call, Response response) throws IOException { try { String result = response.body().string(); System.out.println("result = " + result); Gson gson = new Gson(); final T t = (T) gson.fromJson(result,clazz); handler.post(new Runnable() { @Override public void run() { success(t); } }); } catch (IOException e) { e.printStackTrace(); failure(e); } catch (JsonSyntaxException e) { e.printStackTrace(); failure(e); } } }
//Okhttp 单例 范型的封装 public class OkhttpUtils { private static OkhttpUtils okhttpUtils = null; private OkhttpUtils() { } public static OkhttpUtils getInstance() { if (okhttpUtils == null) { okhttpUtils = new OkhttpUtils(); client = new OkHttpClient.Builder() .readTimeout(20, TimeUnit.SECONDS) .writeTimeout(20, TimeUnit.SECONDS) .connectTimeout(20, TimeUnit.SECONDS) .addInterceptor(new LoggingInterceptor()) .build(); } return okhttpUtils; } private static OkHttpClient client; public void asy(Map<String, String> params, String url, AbstractUiCallBack callBack) { Request request = null; if (params != null) { FormBody.Builder builder = new FormBody.Builder(); for (Map.Entry<String, String> entry : params.entrySet()) { builder.add(entry.getKey(), entry.getValue()); } FormBody body = builder.build(); request = new Request.Builder() .url(url) .post(body) .build(); } else { request = new Request.Builder() .url(url) .build(); } client.newCall(request).enqueue(callBack); } private static final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/png"); public static void postFile(Map<String, String> map, String url, File file, AbstractUiCallBack callBack) { String[] array = file.getAbsolutePath().split("\\/"); MultipartBody.Builder builder = new MultipartBody.Builder(); builder.setType(MultipartBody.FORM); for (Map.Entry<String, String> entry : map.entrySet()) { builder.addFormDataPart(entry.getKey(), entry.getValue()); } builder.addFormDataPart("imageFileName", array[array.length - 1]); if (file.exists() && file.length() > 0) { builder.addFormDataPart("image", array[array.length - 1], RequestBody.create(MEDIA_TYPE_PNG, file)); } MultipartBody body = builder.build(); Request request = new Request.Builder() .url(url) .post(body) .build(); client.newCall(request).enqueue(callBack); } }下面是拦截器的封装
//拦截器 public class LoggingInterceptor implements Interceptor { @Override public Response intercept(Chain chain) throws IOException { Request request = chain.request(); long t1 = System.nanoTime(); // logger.info(String.format("Sending request %s on %s%n%s", // request.url(), chain.connection(), request.headers())); Response response = chain.proceed(request); long t2 = System.nanoTime(); // logger.info(String.format("Received response for %s in %.1fms%n%s", // response.request().url(), (t2 - t1) / 1e6d, response.headers())); System.out.println("t2 = " + (t2-t1)); return response; } }我这里用到了一些图片需要自己去阿里巴巴矢量图标库下载
还需要在drawble下面配置一下这个

Bean包需要自己写三个属性
// 1 显示商家 2 隐藏商家 private int isFirst; // true 表示商家选中 false 相反 private boolean shopSelected; // true 表示 当前商品是选中的 false 相反 private boolean itemSelected;
