Question

我有HomeActivity在viewpager中包含许多片段。现在我有2个片段

AddBalanceFragment
AddSubscriptionFragment

我从两个片段调用onActivityResult，两者都有相同的代码。 onActivityResult首先转到HomeActivity的onActivityResult正常工作AddBalanceFragment它会转到addBalanceFragment的onActivityResult，但当我尝试与AddSubscriptionFragment相同时它也适用于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) {
         }
       }

AddSubscriptionFragment.java

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


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

Answer 1

我用静态变量状态得到它：）

toggleClass("show");

Answer 2

你能确定你在打电话吗

super.onActivityResult(requestCode, resultCode, data);

on fragment的onActivityResult方法。

您甚至不需要在活动中手动调用这些方法

片段中的onActivityResult未被称为childFragment
