这个例程有三个按钮bindButton、unbindButton、getServiceStatusButton
分别是绑定Service、解除绑定、获取Service状态
BindServiceTest.java 在Activity中绑定本地Service,并获取Service的运行状态
public class BindServiceTest extends Activity { Button bindButton,unbindButton,getServiceStatusButton; // 保持所启动的Service的IBinder对象 BindService.MyBinder binder; // 定义一个ServiceConnection对象 private ServiceConnection conn = new ServiceConnection(){ @Override // 当该Activity与Service连接成功时回调该方法 public void onServiceConnected(ComponentName name, IBinder service) { System.out.println("--Service Connected--"); binder = (BindService.MyBinder) service; } // 当该Activity与Service断开连接时回调该方法 @Override public void onServiceDisconnected(ComponentName name) { System.out.println("--Service Disconnected--"); } }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); bindButton = (Button)findViewById(R.id.bind); unbindButton = (Button)findViewById(R.id.unbind); getServiceStatusButton = (Button)findViewById(R.id.getServiceStatus); final Intent intent = new Intent(); intent.setAction("crazyit.service.BIND_SERVICE"); bindButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { bindService(intent, conn, Service.BIND_AUTO_CREATE); } }); unbindButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { unbindService(conn); } }); getServiceStatusButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Toast.makeText(BindServiceTest.this, "Service的count值为"+ binder.getCount(), Toast.LENGTH_SHORT).show(); } }); } }
public class BindService extends Service { private int count; private boolean quit; // 定义onBinder方法所返回的对象 private MyBinder binder = new MyBinder(); // 通过继承Binder来实现IBinder类 public class MyBinder extends Binder{ public int getCount(){ // 获取Service的运行状态:count return count; } } // 必须实现的方法,绑定该Service时回调该方法 @Override public IBinder onBind(Intent intent) { System.out.println("Service is Binded"); // 返回IBinder对象 return binder; } // Service被创建时回调该方法。 @Override public void onCreate() { // TODO Auto-generated method stub super.onCreate(); System.out.println("Service is Created"); new Thread(){ @Override public void run() { while(!quit){ try{ Thread.sleep(1000); }catch(InterruptedException e){ e.printStackTrace(); } count++; } } }.start(); } // Service被断开连接时回调该方法 @Override public boolean onUnbind(Intent intent) { System.out.println("Service is onUnbinded"); return true; } @Override public void onDestroy() { super.onDestroy(); this.quit = true; System.out.println("Service is Destroyed"); } }manifest文件
