Activity#onCreate方法中添加HomeFragment，使用FragmentTransaction#commitNow()、FragmentTransaction#commitNowAllowingStateLoss()或者FragmentTransaction#commit() + fragmentManager.executePendingTransactions()这些方式添加Fragment时，第一个Fragment适配失败。

Environment

• [x] Autosize Version: 1.2.1
• [x] Target Android Version: Android 9.0, api28
• [x] Device Model: huawei mate 10 pro
• [x] Device Resolution: 1080px * 2160px
• [x] Design Size On AndroidManifest: 375dp * 667dp

Bug Description:

需求：Activity中存在多个，第一个Fragment想实现按照高度适配。

在Activity#onCreate方法中添加HomeFragment，使用commit方法添加Fragment时，适配没有问题；

但是使用FragmentTransaction#commitNow()、FragmentTransaction#commitNowAllowingStateLoss()或者FragmentTransaction#commit() + fragmentManager.executePendingTransactions()这些方式添加Fragment时，添加的第一个Fragment就不会按照高度适配，会跟随父Activity的适配走。

HomePageFragment实现了 CustomAdapt接口，isBaseOnWidth返回false。
public class HomePageFragment extends Fragment implements CustomAdapt {
    @Override
    public boolean isBaseOnWidth() {
        Log.e("autosize","HomePageFragment#isBaseOnWidth");
        return false;
    }

    @Override
    public float getSizeInDp() {
        Log.e("autosize","HomePageFragment#getSizeInDp");
        return 1334 / 2.0f;
    }
}

MainActivity#onCreate中添加Fragment的方法：
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
// 1
transaction.add(R.id.fl_container, frag, fragmentTags[currentTabIndex]).show(frag).commitNow();
// 2
// transaction.add(R.id.fl_container, frag, fragmentTags[currentTabIndex]).show(frag).commitNowAllowingStateLoss();
// 3
// transaction.add(R.id.fl_container, frag).show(frag).commit();
// fragmentManager.executePendingTransactions();
