初学，不知道是不是还有其他方法。

MainActivity.java

package com.example.aphero.myinterface;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.widget.TextView;public class MainActivity extends AppCompatActivity implements Myinterface.Callback {    private TextView bitTextview;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        bitTextview= (TextView) findViewById(R.id.bitTextview);        Myinterface myinterface = new Myinterface();        myinterface.setCallback(this);    }    @Override    public void OnUpdate(int bit) {        bitTextview.setText("aphero:"+bit);    }}

MyInterface.java

package com.example.aphero.myinterface;import android.os.Handler;import android.os.HandlerThread;import android.os.Looper;import android.util.Log;/** * Created by aphero on 17-5-23. * 内部类实现接口，必须传递接口的实现，即MainActivity实现了Myinterface.Callback, * 所以必须将MainActivity.this传递给Callback mCallback */public class Myinterface {    private final static String TAG="Myinterface";    private final Handler mMainHandler;    private final Handler mHandler;    private  Callback mCallback;    private int count=0;    public interface Callback{        public void OnUpdate(int bit);    }    public Myinterface() {        HandlerThread thread = new HandlerThread("myinterface");        thread.start();        mHandler = new Handler(thread.getLooper());        mMainHandler = new Handler(Looper.getMainLooper());        mHandler.post(handlerpost);    }    public void setCallback(Callback mCallback){        this.mCallback = mCallback;    }    private void postUpdate(final int bit){        mMainHandler.post(new Runnable() {            @Override            public void run() {                if (mCallback!=null)  mCallback.OnUpdate(bit);                else  Log.i(TAG,"mCallback is null");            }        });    }    private Runnable handlerpost = new Runnable() {        @Override        public void run() {            postUpdate(count++);            mHandler.postDelayed(handlerpost,1000);        }    };}
