bindservice使用例子-创新互联

MainActivity.java如下

package com.example.bindservice;

import com.example.bindservice.BindService.MyBinder;

import android.os.Bundle;

import android.os.IBinder;

import android.app.Activity;

import android.content.ComponentName;

import android.content.Context;

import android.content.Intent;

import android.content.ServiceConnection;

import android.util.Log;

import android.view.Menu;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

public class MainActivity extends Activity {

private Button startBtn;

private Button stopBtn;

private boolean flag;

private static final String TAG = "BindService";

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

flag = false;

startBtn = (Button)this.findViewById(R.id.startBtn);

stopBtn = (Button)this.findViewById(R.id.stopBtn);

startBtn.setOnClickListener(listener);

stopBtn.setOnClickListener(listener);

}

private OnClickListener listener = new OnClickListener() {

    @Override

    public void onClick(View v) {

      // TODO Auto-generated method stub

      switch (v.getId()) {

      case R.id.startBtn:

         bindService();

        break;

      case R.id.stopBtn:

        unBind();

        break;

      default:

        break;

      }

    }

  };

  private void bindService(){

    Intent intent = new Intent(MainActivity.this,BindService.class);

    bindService(intent, conn, Context.BIND_AUTO_CREATE);

  }

  private void unBind(){

    if(flag == true){

      Log.i(TAG, "BindService-->unBind()");

      unbindService(conn);

      flag = false;

    }

  }

  private ServiceConnection conn = new ServiceConnection() {

    @Override

    public void onServiceDisconnected(ComponentName name) {

      // TODO Auto-generated method stub

    }

    @Override

    public void onServiceConnected(ComponentName name, IBinder service) {

      // TODO Auto-generated method stub

      MyBinder binder = (MyBinder)service;

      BindService bindService = binder.getService();

      bindService.MyMethod();

      flag = true;

    }

  };

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

}

BindService.java如下

package com.example.bindservice;

import android.app.Service;

import android.content.Intent;

import android.os.Binder;

import android.os.IBinder;

import android.util.Log;

public class BindService extends Service {

private static final String TAG = "BindService";

public void MyMethod(){

for(int i = 0; i < 100; i++)

{

Log.i(TAG, "BindService-->MyMethod()");

}

  }

@Override

public IBinder onBind(Intent arg0) {

// TODO Auto-generated method stub

return myBinder;

}

public class MyBinder extends Binder{

    public BindService getService(){

      return BindService.this;

    }

  }

private MyBinder myBinder = new MyBinder();

}
