即添加了两个按钮：“绑定服务”和“解绑服务”按钮。
3、修改MainActivity.java文件
package com.example.testservice;
import com.example.testservice.MyService.MusicBinder;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Bundle;
import android.os.IBinder;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity implements OnClickListener{
private Button startService_Button;
private Button stopService_Button;
private Button bindService_Button;
private Button unbindService_Button;
private MyService.MusicBinder musicBinder;
//创建ServiceConnection,在绑定服务的时候会用到。
private ServiceConnection connection = new ServiceConnection() {
@Override
public void onServiceDisconnected(ComponentName service) {
}
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
//类型转换
musicBinder = (MyService.MusicBinder) service;
//指挥服务需要做的工作
musicBinder.ready();
musicBinder.play();
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//获取开启服务按钮
startService_Button = (Button) findViewById(R.id.button1);
//获取停止服务按钮
stopService_Button = (Button) findViewById(R.id.button2);
//获取绑定服务按钮
bindService_Button = (Button) findViewById(R.id.button3);
//获取解绑服务按钮
unbindService_Button = (Button) findViewById(R.id.button4);
//调用点击事件
startService_Button.setOnClickListener(this);
stopService_Button.setOnClickListener(this);
bindService_Button.setOnClickListener(this);
unbindService_Button.setOnClickListener(this);
}
/**
* 点击事件
*/
@Override
public void onClick(View view) {
switch(view.getId()){
case R.id.button1:
//“开启服务”按钮

startService(startIntent);
break;

}
@Override

getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
