Android 进程间服务通信

核心提示：{public String getCurrentDataTime() {return (getCurrentDataTimeImpl());}};synchronized private String getCurrentDataTimeImpl() {Date date=new Date();return (dat

{

public String getCurrentDataTime() {

return (getCurrentDataTimeImpl());

}

};

synchronized private String getCurrentDataTimeImpl() {

Date date=new Date();

return (date.toLocaleString());

}

@Override

public IBinder onBind(Intent intent) {

return (binder);

}

}

3.现在编写一个Activity,来消费这个服务:

Java代码

public class ServicesDemo2 extends Activity {

private IDataTimeService service = null;

private Intent serviceIntent = null;

private WebView browser;

private ServiceConnection svcConn = new ServiceConnection() {

public void onServiceConnected(ComponentName className, IBinder binder) {

service = IDataTimeService.Stub.asInterface(binder);

browser.postDelayed(new Runnable() {

public void run() {

updateForecast();

}

}, 1000);

}

public void onServiceDisconnected(ComponentName className) {

service = null;

}

};

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

browser = (WebView) findViewById(R.id.webkit);

serviceIntent = new Intent(this, DataTimeServiceImpl.class);

//绑定一个服务

bindService(serviceIntent, svcConn, BIND_AUTO_CREATE);

}

@Override

public void onResume() {

super.onResume();

/**

注册广播消息的接收者,在android中服务与Activity的通信依靠广播发送消息,然后由Activity注册的接收者

接收到消息,进行相应的处理这里使用DataTimeServiceImpl.BROADCAST_ACTION来过滤,表明它只接收
