別のアクティビティを呼び出すメイン アクティビティがあります。戻るボタンが押されたときに 2 番目のアクティビティを完全に破棄したい。onDestroy メソッドは、戻るボタンを押すと常に呼び出されますが、Eclipse LogCat では、破棄されたアクティビティに属するログがまだ表示されます (画面の向きの変更に設定しました)。それは Eclipse のバグですか、それとも 2 番目のアクティビティが破棄されないのでしょうか?
これは私の PhotoActivity で、CameraActivity の後に呼び出されます。
@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");
}
そして、これは私のLogCatです：

ご覧のとおり、写真のアクティビティは破棄されています (破棄ログをさらにインデントしました) が、電話を動かしてもログ「方向機能: 度」が表示され続けます。
