Android中Activity和Service的绑定(二)
public class BinderActivity extends Activity { private Button startBinderServices; private Button stopBinderServices; private Boolean isConnected = false; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.binder); startBinderServices = (Button) findViewById(R.id.btnstartBinderServices); stopBinderServices = (Button) findViewById(R.id.btnstopBinderServices); startBinderServices.setOnClickListener(listener); stopBinderServices.setOnClickListener(listener); } private OnClickListener listener = new OnClickListener() { public void onClick(View v) { switch (v.getId()) { case R.id.btnstartBinderServices: bindService(); break; case R.id.btnstopBinderServices: unbind(); break; default: break; } } }; private void unbind() { if (isConnected) { unbindService(conn); isConnected = false; } } private void bindService() { Intent intent = new Intent(BinderActivity.this, BindService.class); bindService(intent, conn, Context.BIND_AUTO_CREATE); } private ServiceConnection conn = new ServiceConnection() { public void onServiceDisconnected(ComponentName name) { isConnected = false; } public void onServiceConnected(ComponentName name, IBinder binder) { MyBinder myBinder = (MyBinder)binder; BindService service = myBinder.getService(); isConnected = true; service.MyMethod(); } }; }
