是的,bindService方法也会调用onCreate方法。当调用bindService方法时,如果服务不存在,则会先调用onCreate方法创建服务,然后调用服务的onBind方法。
以下是一个示例代码:
首先,在服务类中实现onCreate和onBind方法:
public class MyService extends Service {
@Override
public void onCreate() {
super.onCreate();
Log.d("MyService", "onCreate");
}
@Nullable
@Override
public IBinder onBind(Intent intent) {
Log.d("MyService", "onBind");
return null;
}
}
然后,在Activity中调用bindService方法:
public class MainActivity extends AppCompatActivity {
private MyService myService;
private boolean isBound = false;
private ServiceConnection serviceConnection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
MyService.MyBinder binder = (MyService.MyBinder) service;
myService = binder.getService();
isBound = true;
}
@Override
public void onServiceDisconnected(ComponentName name) {
isBound = false;
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = new Intent(this, MyService.class);
bindService(intent, serviceConnection, Context.BIND_AUTO_CREATE);
}
@Override
protected void onDestroy() {
super.onDestroy();
if (isBound) {
unbindService(serviceConnection);
isBound = false;
}
}
}
当调用bindService方法时,会触发服务的onCreate方法,可以在服务的onCreate方法中添加日志打印。当服务绑定成功时,会触发ServiceConnection的onServiceConnected方法,可以在这个方法中获取到服务的实例。
