我有一个主要活动调用另一个活动。我希望在按下后退按钮时完全销毁第二个活动。当我按下返回按钮时，总是调用 onDestroy 方法，但在 Eclipse LogCat 中，我仍然看到属于被破坏活动的日志（我在屏幕方向更改时设置它们）。是 Eclipse 错误还是我的第二个活动永远不会被破坏？
这是我的 PhotoActivity，在 CameraActivity 之后调用：
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.photo);
[…]
OrientationEventListener mOrientationEventListener = new OrientationEventListener(this, SensorManager.SENSOR_DELAY_NORMAL)
{
@Override
public void onOrientationChanged(int orientation)
{
mDeviceOrientation = orientation;
int norientation = 90*Math.round(mDeviceOrientation / 90);
if(norientation == 360)
{
norientation = 0;
}
Log.d("photo","orientation function:"+norientation);
}
};
if(mOrientationEventListener.canDetectOrientation())
{
mOrientationEventListener.enable();
}
}
@Override
protected void onDestroy() {
super.onDestroy();
Log.d("photo","destroy");
}
这是我的 LogCat：

如您所见，照片活动已被破坏（我缩进了更多的破坏日志），但是当我移动手机时，日志“orientation function：degrees”继续出现。
