Android Retrofit+Rxjava+MVP+EventBus+ButterKnife实现接口登录（无正则表达式）

效果图：





Retrofit 内部封装了okhttp+gson解析，Rxjava用来灵活地切换线程，

先注入依赖：

//retrofit
compile 'com.squareup.retrofit2:retrofit:+'
compile 'com.squareup.retrofit2:converter-gson:+'
//Rxjava2
compile 'io.reactivex.rxjava2:rxjava:+'
compile 'io.reactivex.rxjava2:rxandroid:+'
//让retrofit支持Rxjava2
compile 'com.squareup.retrofit2:adapter-rxjava2:+'

//黄油刀butterKnife
annotationProcessor 'com.jakewharton:butterknife-compiler:+'
compile 'com.jakewharton:butterknife:+'
//EventBus
compile 'org.greenrobot:eventbus:+'//eventBus引用

最后注册清单，记得加网络权限和跳转的activity：

<uses-permission android:name="android.permission.INTERNET"/>
<activity android:name=".SecondActivity"/>

项目结构图：



首先是RetrofitManager 的工具类：

public class RetrofitManager {
//这个接口后期可以写个公共类的属性
public static final String BASE_URL = "http://120.27.23.105/";
private final Retrofit mRetrofit;

public static class SINGLE_HOLDER {
public static final RetrofitManager INSTANCE = new RetrofitManager(BASE_URL);
}

public static RetrofitManager getInstance() {
return SINGLE_HOLDER.INSTANCE;
}

private RetrofitManager(String baseUrl) {
mRetrofit = buildRetrofit();
}

private OkHttpClient buildOkHttpClient() {
return new OkHttpClient.Builder()
.connectTimeout(10000, TimeUnit.MILLISECONDS)
.build();
}

private Retrofit buildRetrofit() {
return new Retrofit.Builder()
.client(buildOkHttpClient())
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build();
}

public <T> T create(Class<T> clazz) {
return mRetrofit.create(clazz);
}
}

然后是请求网络接口的方法类RetrofitAPIs:

public interface RetrofitAPIs {
//get
//    用@Query修饰拼接参数
//    @GET("user/login")
//    Observable<LoginBean> login(@Query("mobile") String mobile, @Query("password") String password);

//post
@FormUrlEncoded
@POST("user/login")
Observable<LoginBean> login(@Field("mobile") String mobile, @Field("password") String password);
}

bean类：

public class LoginBean {
/**
* msg : 登录成功
* code : 0
* data : {"age":null,"appkey":"679455a233086e26","appsecret":"F259D879B03CCA7C403B9A90A5B8F41A","createtime":"2018-01-03T09:57:35","email":null,"fans":null,"follow":null,"gender":null,"icon":null,"latitude":null,"longitude":null,"mobile":"17600044511","money":null,"nickname":null,"password":"7F14BAAF818358E25E2D9C5259AA47DD","praiseNum":null,"token":"2F8EBE49EE227C2017C470689C62E524","uid":3881,"userId":null,"username":"17600044511"}

第一个布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="50dp"
android:gravity="center_horizontal"
android:orientation="horizontal">

<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:src="@mipmap/ic_launcher_round" />
</LinearLayout>

<EditText

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

其次是view层定义接口，接口里面定义：登录成功(LoginSurccess)和登录失败(LoginFaild)的抽象方法：

public interface LoginIView  {
void LoginSurccess(LoginBean loginBean);
void LoginFaild(Throwable e);
}

Model层：

public class LoginIModel  {
public Observable<LoginBean> login(String name, String pass) {
RetrofitAPIs retrofitAPIs = RetrofitManager.getInstance().create(RetrofitAPIs.class);
return retrofitAPIs.login(name, pass);
}
}

presenter层IPresenter是基类公共的可以在任何项目中通用：

public abstract class IPresenter<T extends IView> {
protected T view;

public IPresenter(T view) {
this.view = view;
init();
}

protected abstract void init();
}

再就是LoginPresenter类：

public class LoginIPresenter extends IPresenter<LoginIView>{

private LoginIModel loginIModel;
private Observable<LoginBean> observableLogin;

public LoginIPresenter(LoginIView view) {
super(view);
}

@Override
protected void init() {
loginIModel = new LoginIModel();
}
public void login(String name,String pass){
observableLogin = loginIModel.login(name, pass);
observableLogin.subscribeOn(Schedulers.io())
.subscribe(new Consumer<LoginBean>() {
@Override
public void accept(LoginBean loginBean) throws Exception {
view.LoginSurccess(loginBean);
}
}, new Consumer<Throwable>() {
@Override
public void accept(Throwable throwable) throws Exception {
view.LoginFaild(throwable);
}
});
}
}

MainActivity类：

public class MainActivity extends AppCompatActivity implements LoginIView {

@BindView(R.id.edt_name)
EditText edtName;
@BindView(R.id.edt_pass)
EditText edtPass;
@BindView(R.id.login_But)
Button loginBut;
@BindView(R.id.new_user)
TextView newUser;
private LoginIPresenter loginIPresenter;
private String pass;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
loginIPresenter = new LoginIPresenter(this);
}

@OnClick(R.id.login_But)
public void onLoginButClicked() {
String name = edtName.getText().toString();
pass = edtPass.getText().toString();
loginIPresenter.login(name, pass);
}

@OnClick(R.id.new_user)
public void onNewUserClicked() {
Toast.makeText(this, "等待完善...", Toast.LENGTH_SHORT).show();
}

@Override
public void LoginSurccess(LoginBean loginBean) {
EventBus.getDefault().postSticky(loginBean);
Log.e("+++++++++++++++++++", "访问数据:" + "/rn" + loginBean.toString());
if (loginBean.getCode().equals("0")) {
startActivity(new Intent(this, SecondActivity.class));
}
}

@Override
public void LoginFaild(Throwable e) {
Log.e("+++++++++++++++++++", "登录失败,失败原因:" + "/rn" + e.getMessage().toString());
}
}

第二个activity：

public class SecondActivity extends Activity {
@BindView(R.id.copy_but)
Button copyBut;
@BindView(R.id.copy_name)
TextView copyName;
@BindView(R.id.copy_pass)
TextView copyPass;
private LoginBean.DataBean data;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second_layout);
ButterKnife.bind(this);
EventBus.getDefault().register(this);

}

//EventBus的具体事件
@Subscribe(sticky = true)  //形容接受的方法 ， 接受的方法的方法名字自定义，参数是 bean类
public void saveEventBus1(LoginBean loginBean) {
Toast.makeText(this, "接受到了", Toast.LENGTH_SHORT).show();
data = loginBean.getData();
copyName.setText(data.getMobile());
copyPass.setText(data.getPassword());
}

//销毁EventBus
@Override
protected void onDestroy() {
super.onDestroy();
EventBus.getDefault().unregister(this);
}

@OnClick(R.id.copy_but)
public void onViewClicked() {
copyName.setText(data.getMobile());
copyPass.setText(data.getPassword());
}
}

有些匆忙，回头再做修改
