上一遍文章中写了接口回调的模板，这篇文章用rxjava来实现接口回调的功能

（接口回调：http://blog.csdn.net/michael1112/article/details/53573830)

1. 结构

2. gradle

dependencies {    compile fileTree(dir: 'libs', include: ['*.jar'])    testCompile 'junit:junit:4.12'    compile 'com.android.support:appcompat-v7:25.0.0'    compile 'io.reactivex:rxandroid:1.2.1'    compile 'io.reactivex:rxjava:1.1.6'}

3.MainActivity.java

package callback.jdjz.com.rxjava_replace_callback;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.util.Log;import android.view.View;import android.widget.Button;import rx.Observable;import rx.Subscriber;import rx.android.schedulers.AndroidSchedulers;import rx.functions.Action1;import rx.schedulers.Schedulers;import android.net.Uri;import rx.functions.Action1;public class MainActivity extends AppCompatActivity {    Button button;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        button = (Button) findViewById(R.id.btn_rxjava);        final ManagerFields managerFields  = new ManagerFields(this);        Log.d("MainActivity","Thread Name:"+Thread.currentThread().getName().toString()+                " \n Thread id:"+Thread.currentThread().getId());        final Observable observable = Observable.create(new Observable.OnSubscribe<Long>(){            @Override            public void call(Subscriber<? super Long> subscriber) {                Long bjtime = TimeUtil.getBJTime();                subscriber.onNext(bjtime);                subscriber.onCompleted();            }        }).subscribeOn(Schedulers.io());        button.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                observable.observeOn(AndroidSchedulers.mainThread())                        .subscribe(new Action1<Long>() {                            @Override                            public void call(Long bjtime) {                                managerFields.doSomething(bjtime);                            }                        });            }        });    }}

3. ManagerFields.java

package callback.jdjz.com.rxjava_replace_callback;import android.content.Context;import android.util.Log;/** * Created by tchl on 2016-12-12. */    public class ManagerFields {    Context mContext;    public ManagerFields(Context mContext) {        this.mContext = mContext;    }    public void doSomething(long bjTime){        Log.d("ManagerFields","Thread Name:"+Thread.currentThread().getName().toString()+                " \n Thread id:"+Thread.currentThread().getId());        Log.d("ManagerFields","Time :"+bjTime);    }    }

4, TimeUtil.java

package callback.jdjz.com.rxjava_replace_callback;import android.util.Log;import java.io.IOException;import java.net.MalformedURLException;import java.net.URL;import java.net.URLConnection;import java.util.Date;/** * Created by tchl on 2016-12-12. */public class TimeUtil {    static  Long    getBJTime() {        URL url = null;        try {            url = new URL("http://www.baidu.com");        } catch (MalformedURLException e) {            e.printStackTrace();        }        URLConnection uc = null;// 生成连接对象        try {            uc = url.openConnection();        } catch (IOException e) {            e.printStackTrace();        }        try {            uc.connect(); // 发出连接        } catch (IOException e) {            e.printStackTrace();        }        long ld = uc.getDate(); // 取得网站日期时间        Date date = new Date(ld); // 转换为标准时间对象        // 分别取得时间中的小时，分钟和秒，并输出        Log.d("TimeUtil","Thread Name:"+Thread.currentThread().getName().toString()+                " \n Thread id:"+Thread.currentThread().getId());        return date.getTime();    }}
