public interface Inters { @GET("product/getCarts") Observable<AddBean> gets(@Query("uid") int uid);}

Retrofit+Rxjava+OkHttp的结合框架请求的,
public class RetrofitUnitl { private Retrofit mRetrofit; private String baseUrl; OkHttpClient client; private static RetrofitUnitl mRetrofitManager; private RetrofitUnitl(String baseUrl,OkHttpClient client){ this.baseUrl=baseUrl; this.client=client; initRetrofit(); } public static synchronized RetrofitUnitl getInstance(String baseUrl,OkHttpClient client){ if (mRetrofitManager == null){ mRetrofitManager = new RetrofitUnitl(baseUrl,client); } return mRetrofitManager; } private void initRetrofit() { mRetrofit = new Retrofit.Builder() .baseUrl(baseUrl) .addConverterFactory(GsonConverterFactory.create()) .addCallAdapterFactory(RxJavaCallAdapterFactory.create()) .client(client) .build(); } public <T> T setCreate(Class<T> reqServer) { return mRetrofit.create(reqServer); }}
下面直接开始MVP
V层
public interface IGouView { void onsuccer(AddBean bean);//成功的方法}M层
public class GouModel { ScuMod scuMod; public void setScuMod(ScuMod scuMod) { this.scuMod = scuMod; } //自己定义一个请求方法 public void Succes(){ OkHttpClient ok = new OkHttpClient.Builder() .build(); //请求数据 RetrofitUnitl.getInstance("http://120.27.23.105/",ok) .setCreate(Inters.class) .gets(98) .observeOn(AndroidSchedulers.mainThread()) .subscribeOn(Schedulers.io()) .subscribe(new Subscriber<AddBean>() { @Override public void onCompleted() { } @Override public void onError(Throwable e) { } @Override public void onNext(AddBean bean) { scuMod.MScus(bean); Log.e("===========",bean.getData().get(0).getSellerName());; } }); } //定义一个接口 public interface ScuMod{ void MScus(AddBean bean); }}P层,我用的弱引用解绑,防止内存泄漏,可以不写。
public class GouPresenter implements GouModel.ScuMod { //弱引用解绑 WeakReference<IGouView> view; GouModel model; public GouPresenter( IGouView view) { attach(view); model = new GouModel(); model.setScuMod(this); } @Override public void MScus(AddBean bean) { view.get().onsuccer(bean); } //我们在写一个方法拿到我们的请求 public void ShowPer(){ model.Succes(); } //绑定 public void attach(IGouView views){ view = new WeakReference(views); } //解绑方法 public void detach(){ view.clear(); }}自定义一个plusview
public class plusview extends LinearLayout { Button revserse,tianjian; EditText edittext; private int mcount = 1;//定义一个常量 用于购物车就入时默认显示为1 public plusview(Context context) { super(context); } public plusview(Context context, AttributeSet attributeSet){ super(context,attributeSet); //首先加载布局文件 View view = View.inflate(context, R.layout.plus_layout,null); //初始化控件 revserse = view.findViewById(R.id.revserse);//减号 tianjian = view.findViewById(R.id.tianjian);//加好 edittext = view.findViewById(R.id.edittext);//加号减号中间的输入框 //控件初始化玩之后 控件设置点击事件 revserse.setOnClickListener(new OnClickListener() { //减号的点击事件 @Override public void onClick(View view) { String trims = edittext.getText().toString().trim();//获取输入框的值去掉空格 int coun = Integer.valueOf(trims);//把从输入框的得到的值转换成整形 if (coun>1){ mcount = coun-1; edittext.setText(mcount+""); if (listener!=null){ listener.click(mcount); } } } }); //加号的点击事件 tianjian.setOnClickListener(new OnClickListener() { @Override public void onClick(View view) { String trim = edittext.getText().toString().trim();//获取输入框的值去掉空格 int coun = Integer.valueOf(trim)+1;//把从输入框的得到的值转换成整形 mcount = coun; edittext.setText(coun+""); if (listener!=null){ listener.click(coun); } } }); //输入框的点击事件 edittext.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); //添加布局 } public plusview(Context context, @Nullable AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } public void setEditText(int num){ if(edittext != null){ edittext.setText(num+""); } } public ClickListener listener; public void setListener(ClickListener listener ){ this.listener=listener; } /** * 加减号的点击事件 */ public interface ClickListener{ public void click(int coun); }}

Bean包要手动添加这三个定义的
// 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;
代码完事以后,记得在清单文件中加入权限
<uses-permission android:name="android.permission.INTERNET"/><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />依赖就不导了
