Kotlin_Recyclerview_Rxjava的封装

View层

interface ViewIn {    fun Succers(bn: bean)   fun Filde(e: Exception)}

Modle层接口

interface Modle {    fun Succers(bn: bean)   fun   Filde(e: Exception)}

Modle层实体类

class Modles {    fun getdata(modle: Modle) {       var ok = OkHttpClient.Builder()       RetrofitUnitl.getInstance("http://japi.juhe.cn", ok.build())               .setCreate<ViewObj>(ViewObj::class.java)               .getdata()               .observeOn(AndroidSchedulers.mainThread())               .subscribeOn(Schedulers.io())              .subscribe {                  next ->                  modle.Succers(next!!)                }    }}

Presenter层

class presenter  {    lateinit var  wr :WeakReference<ViewIn>     internal lateinit var md :Modles    constructor(wr: ViewIn) {        datach(wr as MainActivity)        this.md = Modles()    }    fun xinyuayn(){        md.getdata(object :Modle{            override fun Filde(e: Exception) {                wr.get()!!.Filde(e)            }            override fun Succers(bn: bean) {               wr.get()!!.Succers(bn)            }        })    }    // 绑定 内存泄漏    fun datach(view: MainActivity) {        wr = WeakReference(view)    }    //解绑    fun data() {        wr.clear()    }}

App

class App : Application() {    override fun onCreate() {        super.onCreate()        Fresco.initialize(this)    }}

网络请求接口

interface ViewObj {    @GET("/comic/book?key=f54c4c57143b8fad9bf3193cab52a81c")    fun getdata() : Observable<bean>}

自己封装的Rxjava+retrofit

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);    }}

适配器

class KolintApdata (context1: Context) : RecyclerView.Adapter<KolintApdata.IViewHodler>() {   var context :Context=context1    var list : ArrayList<Book> = ArrayList()    fun addData(bn : bean) {        list.addAll(bn.result.bookList)        notifyDataSetChanged()    }    override fun onCreateViewHolder(parent: ViewGroup?, viewType: Int): IViewHodler {//        TODO("not implemented") //To change body of created functions use File | Settings | File Templates.        var view = LayoutInflater.from(context).inflate(R.layout.rvlayout,parent,false)        return IViewHodler(view)    }    override fun onBindViewHolder(holder: IViewHodler?, position: Int) {//        TODO("not implemented") //To change body of created functions use File | Settings | File Templates.        holder!!.item_textview.setText(list.get(position).name)        Glide.with(context).load(list.get(position).coverImg).into(holder!!.item_imageview)    }    override fun getItemCount(): Int {//        TODO("not implemented") //To change body of created functions use File | Settings | File Templates.        return list.size    }    class IViewHodler(view : View) : RecyclerView.ViewHolder(view) {         var item_imageview : ImageView         var item_textview : TextView        init {            item_imageview = view.findViewById(R.id.iv)            item_textview = view.findViewById(R.id.tv)        }    }}

适配器布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout    android:orientation="horizontal"    xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="wrap_content">    <ImageView        android:id="@+id/iv"        android:layout_width="150dp"        android:layout_height="150dp">    </ImageView>    <TextView        android:id="@+id/tv"        android:layout_width="50dp"        android:layout_height="50dp" /></LinearLayout>

主Activity

class MainActivity : AppCompatActivity(),ViewIn {     lateinit var  kn : KolintApdata     private  var rv_main : RecyclerView? = null;     lateinit var    pt : presenter    override fun onCreate(savedInstanceState: Bundle?) {        super.onCreate(savedInstanceState)        setContentView(R.layout.activity_main)        rv_main = findViewById(R.id.rv_main);        pt = presenter(this)        pt.xinyuayn()    }    override fun Succers(bn: bean) {        val manager = LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false)        kn =  KolintApdata(this)        rv_main!!.setLayoutManager(manager     );        rv_main!!.setAdapter(kn)        kn.addData(bn)    }    override fun Filde(e: Exception) {            }    //内存泄漏     override fun onDestroy() {        super.onDestroy()        //解绑        pt.data()    }}

主Activity布局文件

<?xml version="1.0" encoding="utf-8"?><LinearLayout    android:orientation="vertical"    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="wrap_content"    tools:context="com.example.kotlinrecyclerview.MainActivity"><android.support.v7.widget.RecyclerView    android:id="@+id/rv_main"    android:layout_width="match_parent"    android:layout_height="wrap_content"></android.support.v7.widget.RecyclerView></LinearLayout>
