Question

我有一个ActionBarActivity，有时会显示DialogFragment。当我在旋转后尝试关闭对话框时，它崩溃并出现IllegalStateException：Activity已被销毁。我无法将Activity设置为

            android:configChanges="orientation|screenSize|keyboardHidden"

因为我需要在旋转时重新绘制布局。

/**
 * Shows Loading progress dialog
 */
private void showProgress() {
    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    Fragment prev = getSupportFragmentManager().findFragmentByTag(LoadingDialogFragment.FRAGMENTMANAGERTAG);
    if (prev != null) {
        ft.remove(prev);
    }
    // Create and show the dialog.
    mProgressDialog = LoadingDialogFragment.newInstance("", getString(R.string.string_loading));
    mProgressDialog.show(ft, LoadingDialogFragment.FRAGMENTMANAGERTAG);
}

private void hideProgress() {
    if (mProgressDialog != null) {
        Log.d(getClass().getSimpleName(), "hideDialogNoConnection quita dialog");
        FragmentManager manager = getSupportFragmentManager();
        manager.beginTransaction().remove(mProgressDialog).addToBackStack(null).commitAllowingStateLoss();
        Log.d(getClass().getSimpleName(), "hideDialogNoConnection quita dialog con popBackStack");

        manager.popBackStack();
    }
    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    Fragment prev1 = getSupportFragmentManager().findFragmentByTag(LoadingDialogFragment.FRAGMENTMANAGERTAG);
    if (prev1 != null) {
        ft.remove(prev1);
    }
}

我该怎么办？

- Edit-- 这是logcat：

获取'java.lang.IllegalStateException：活动已被销毁'，同时在旋转后隐藏DialogFragment
