Atlas框架下通过ViewPager+Fragment加载Bundle的Activity不能回调onActivityResult问题解决

现象：MainActivity通过ViewPager+Fragment加载装载HomeActivity、SearchActivity、CategoryActivity、CartActivity、MineActivity。若在HomeActivity内部的Fragment启动新的Bundle Activity，当返回时，Activity生命周期的焦点在MainActivity上

• MainActivity不能回调onActivityResult
• HomeActivity不能回调onActivityResult
• HomeActivity中的Fragment不能回调onActivityResult
• MainActivity的onResume可以回调

可通过Host与Bundle间通信机制解决HomeActivity及其内部Fragment的回调，如RxBus

MainActivity

@Override
protected void onResume() {
    super.onResume();
    NLog.i(TAG, "MainActivity: onResume");
    onBundleActivityResume(mViewPager.getCurrentItem());
}

private void onBundleActivityResume(int position) {
    NLog.i(TAG, "MainActivity: onBundleActivityResume " + position);
    switch (position) {
        case Constants.MAIN_TAB_HOME:
            RxBus.getInstance().post(RxBus.TAG_HOME_RESUME, "home");
            break;
        case Constants.MAIN_TAB_SEARCH:
            RxBus.getInstance().post(RxBus.TAG_SEARCH_RESUME, "search");
            break;
        case Constants.MAIN_TAB_CATEGORY:
            RxBus.getInstance().post(RxBus.TAG_CATEGORY_RESUME, "category");
            break;
        case Constants.MAIN_TAB_CART:
            RxBus.getInstance().post(RxBus.TAG_CART_RESUME, "cart");
            break;
        case Constants.MAIN_TAB_MINE:
            RxBus.getInstance().post(RxBus.TAG_MINE_RESUME, "mine");
            break;
        default:
            break;
    }
}

HomeActivity

@RxBusSubscribe(tag = RxBus.TAG_HOME_RESUME)
public void onHomeActivityResume(String tab) {
    NLog.i(TAG, "HomeActivity: onHomeActivityResume");
    switch (mHomeViewPager.getCurrentItem()) {
        case 0:

            break;
        case 1:

            break;
        case 2:  //Collect
            mHomeCollectFragment.refreshCollectGoodsList();
            break;
        default:
            break;
    }
}
