android中接口實現更新UI方法

初學，不知道是不是還有其他方法。

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.
 * 內部類實現接口，必須傳遞接口的實現，即MainActivity實現了Myinterface.Callback,
 * 所以必須將MainActivity.this傳遞給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);
        }
    };


}
