android - fragment 中的 onActivityResult 未称为 childFragment

Question

我有HomeActivity在 viewpager 中包含许多 fragment 。现在我有 2 个 fragment

1. AddBalanceFragment

2. AddSubscriptionFragment

我调用 onActivityResult来自两个 fragment 并且都具有相同的代码。 onActivityResult 先到HomeActivity 的onActivityResult使用 AddBalanceFragment 工作正常它转到 addBalanceFragment 的 onActivityResult但是当我尝试与 AddSubscriptionFragment 相同时它还转到 AddBalanceFragment 的 onActivityResult

//nestedfragments contains 4 fragments   3rd is addBalanceFragment and 4th AddsubsprtionFragment


// HomeActivity.java

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Log.e(TAG, "onActivityResult");
    // notifying nested fragments (support library bug fix)
    final FragmentManager childFragmentManager = getSupportFragmentManager();

    if (childFragmentManager != null) {
        final List<Fragment> nestedFragments = childFragmentManager.getFragments();

        if (nestedFragments == null || nestedFragments.size() == 0) return;

        for (Fragment childFragment : nestedFragments) {
            if (childFragment != null && !childFragment.isDetached() && !childFragment.isRemoving()) {

                childFragment.onActivityResult(requestCode, resultCode, data);
            }
        }
    }
}

AddBalanceFragment.java

public void onActivityResult(int requestCode, int resultCode, Intent data) {


    if (requestCode == 1001) {
        if (resultCode == -1) {
         }
       }

添加订阅 fragment .java

public void onActivityResult(int requestCode, int resultCode, Intent data) {


    if (requestCode == 1001) {
        if (resultCode == -1) {
         }
       }

我用静态变量状态得到它:)

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Log.e(TAG, "onActivityResult HomeActivity");
    // notifying nested fragments (support library bug fix)

    final List<Fragment> nestedFragments = getSupportFragmentManager().getFragments();
    for (int i = 0; i < nestedFragments.size(); i++)
        if (nestedFragments == null || nestedFragments.size() == 0) return;

    for (Fragment childFragment : nestedFragments) {
        if (childFragment != null && !childFragment.isDetached() && !childFragment.isRemoving()) {
            Log.e(TAG, "childFragment :" + childFragment.toString());
            //   Log.e(TAG, "childFragment :"+childFragment.getParentFragment().getTag());

            if (state.equalsIgnoreCase("AddBalance")) {
                if (childFragment.toString().contains("AddBalanceFragment")) {
                    childFragment.onActivityResult(requestCode, resultCode, data);
                }
            }
            if (state.equalsIgnoreCase("AddSubcription")) {
                if (childFragment.toString().contains("AddSubscriptionFragment")) {
                    childFragment.onActivityResult(requestCode, resultCode, data);
                }
            }


        }
    }


}
