1.添加依赖
implementation 'com.squareup.okhttp3:okhttp:3.8.1'
implementation 'com.squareup.okhttp3:logging-interceptor:3.4.1'
implementation 'io.reactivex:rxjava:1.1.6'
// Retrofit的rx解析库
implementation 'com.squareup.retrofit2:retrofit:2.1.0'
implementation 'com.squareup.retrofit2:adapter-rxjava:2.1.0'
// Retrofit的gson库字符串库
implementation 'com.squareup.retrofit2:converter-gson:2.1.0'
implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'
implementation 'com.orhanobut:logger:1.8'
//解决Android3.0以后不能butterknife问题
implementation 'com.jakewharton:butterknife:8.4.0'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'
implementation 'io.reactivex:rxandroid:1.2.1'
2.copy Tutils工具类
public class Ttil {
public static
try {
return ((Class) ((ParameterizedType) (o.getClass()
.getGenericSuperclass())).getActualTypeArguments()[i])
.newInstance();
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStac kTrace();
} catch (ClassCastException e) {
e.printStackTrace();
}
return null;
}
public static Class forName(String className) {
try {
return Class.forName(className);
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
return null;
}
}
3创建retrofit对象 RetrofitManager
public class RetrofitManager {
//地址
private String BaseURL = Contents.BASEURL;
private static OkHttpClient mOkHttpClient;
private Retrofit mRetrofit;
/**
* 构建Retrofit
*
* @return
*/
public Retrofit build() {
initOkHttpClient();
initRetrofit();
return mRetrofit;
}
public RetrofitManager() {
}
protected void initRetrofit() {
mRetrofit = new Retrofit.Builder()
.baseUrl(BaseURL)
.client(mOkHttpClient)
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create(new Gson()))
.build();
}
private void initOkHttpClient() {
//拦截器，用于输出网络请求和结果的 Log
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
//初始化OkHttpClient
mOkHttpClient = new OkHttpClient.Builder()
.addInterceptor(interceptor)
.retryOnConnectionFailure(true)
.connectTimeout(15, TimeUnit.SECONDS)
.build();
}
}
4.Contents 网址(也就是3baseurl)
public class Contents {
public static String BASEURL ="https://api.yunxuekeji.cn/";
}
5.LoginService接口
public interface LoginService {
@FormUrlEncoded
@POST("api/account/login")
rx.Observable
phone, @Field("password") String psw);
@GET("yunxue_app_api/diction/getdictionaryswithpid/KECHENGFENLEI")
rx.Observable
}
6.新建LoginContract（契约类,以Contract结尾），有了契约类后自动生成相关的base类
public class LoginContract {
public interface View extends BaseView {
void succ(Bean bean);
}
public interface Model extends BaseModel {
rx.Observable
}
public abstract static class Presenter extends BasePresenter {
abstract void login(String phone,String psw);
}
}
7.BaseModel初始化retrofit对象（BaseView不用搭理）
public interface BaseModel {
public RetrofitManager mretrofit=new RetrofitManager();
}
8.BasePresenter初始化presenter对象
public class LoginModel implements LoginContract.Model{
private LoginService loginService;
public LoginModel() {
loginService = mretrofit.build().create(LoginService.class);
}
public rx.Observable
return loginService.login();2
}
}
9.在LoginContract自动生成的LoginModel中实现未实现的方法
public class LoginModel implements LoginContract.Model{
private LoginService loginService;
public LoginModel() {
loginService = mretrofit.build().create(LoginService.class);
}
public rx.Observable login() {
return loginService.login();2
}
}
10.在LoginContract自动生成的LoginPresenter中实现未实现的方法
public class LoginPresenter extends LoginContract.Presenter{
public void login(String phone, String psw) {
mModel.login()
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Action1() {
@Override
public void call(Bean bean) {
mView.succ(bean);
}
}, new Action1() {
@Override
public void call(Throwable throwable) {
// mView.succ(throwable.getMessage());
}
});
}
}
11.新建App(在baseactivity中一定要使用)
public class App extends Application {
public static AppCompatActivity mActivity;
public static Fragment mLastFragment;
private static Context context;
@Override
public void onCreate() {
super.onCreate();
context = getApplicationContext();
}
public static Context getContext() {
return context;
}
}
12.新建BaseActivity
public abstract class BaseActivity extends AppCompatActivity implements BaseView {
public T mPresenter;
public E mModel;
private FragmentManager manager;
private FragmentTransaction transaction;
private Fragment fragment;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
App.mActivity=this;
init();
}
protected void init() {
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
setContentView(getLayoutResID());
mPresenter = TUtil.getT(this, 0);
mModel = TUtil.getT(this, 1);
if (this instanceof BaseView) mPresenter.setMV(mModel,this );
initFragmentManager();
initView();
}
private void initFragmentManager() {
manager = App.mActivity.getSupportFragmentManager();
transaction = manager.beginTransaction();
}
public Fragment add(int containerId, Class fragmentClass, boolean isChild, Map map){
//用Fragment的名字设置一个tag值
String tag = fragmentClass.getSimpleName();
//使用tag值来判断当前Fragment是否实例化
fragment = manager.findFragmentByTag(tag);
//
if (fragment == null){
try {
//使用单例创建Fragment对象
fragment = fragmentClass.newInstance();
//使用add方法添加到容器中
transaction.add(containerId, fragment,tag);
//调用添加回退栈方法进行栈管理
//addToBackStack(): 添加回退栈
transaction.addToBackStack(tag);
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
}
if (!isChild ) {
if (App.mLastFragment != null){
transaction.hide(App.mLastFragment);
}
}
if (map!=null) {
Bundle bundle=new Bundle();
for (Map.Entry entry : map.entrySet()) {
bundle.putString(entry.getKey(),entry.getValue());
}
}
transaction.show(fragment);
App.mLastFragment=fragment;
transaction.commit();
return fragment;
}
/**
* 获得Layout文件id
* @return
*/
protected abstract int getLayoutResID();
protected abstract void initView();
}
13.新建BaseFragment
public abstract class BaseFragment
BaseModel> extends Fragment {
public P p;
public M m;
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable
ViewGroup container, @Nullable Bundle savedInstanceState) {
View inflate = inflater.inflate(getLayoutId(), container, false);
p = TUtil.getT(this, 0);
m = TUtil.getT(this, 1);
if (this instanceof BaseView) {
p.setMV(m, this);
}
initView(inflate);
initData();
return inflate;
}
protected abstract void initView(View inflate);
protected abstract void initData();
protected abstract int getLayoutId();
}
