在我的應用程序中，我有一個activity（MainActivity）和一些fragments（ServicesFragment，NewAddressFragment）。ServicesFragment用于顯示此內容viewPager，NewAddressFragment用于顯示！ 在這個我使用過，但在其中一個中的一個不調用代碼中發生沖突。 我寫了下面的代碼，請看這個。主要活動 ：getFragmentManager().replace ...fragmentsfragmentsonActivityResultfragments onActivityResultfragments@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) { Fragment servicesFrag = bottomNavAdapter.getItem(mainViewPager.getCurrentItem()); if (servicesFrag instanceof ServicesFragment) { ((ServicesFragment) servicesFrag).onActivityResult(requestCode, resultCode, data); }}服務片段：@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) { Log.e("BazaarPaymentLog", "Result"); Log.e("BazaarPaymentLog", "bazaarRequestCode : " + bazaarRequestCode); if (iabHelper == null) return; if (requestCode == bazaarRequestCode) { String purchaseData = data.getStringExtra("INAPP_PURCHASE_DATA"); if (resultCode == RESULT_OK) { try { JSONObject jo = new JSONObject(purchaseData); purchaseToken = jo.getString("purchaseToken"); productId = jo.getString("productId"); packageName = jo.getString("packageName"); Log.e("BazaarPaymentLog", "purchaseToken : " + purchaseToken); if (iabHelper != null) { iabHelper.handleActivityResult(requestCode, resultCode, data); } } catch (JSONException e) { e.printStackTrace(); } } } else { super.onActivityResult(requestCode, resultCode, data); }}在、調用代碼和非調用代碼中編寫onActivityResult代碼時。MainActivityServicesFragment onActivityResultNewAddressFragment onActivityResult但是當刪除onActivityResult代碼時MainActivity，ServicesFragment 不是調用 onActivityResult代碼和NewAddressFragment 調用 onActivityResult代碼。我該如何解決？

在 MainActivity 的 onActivityResult 里面使用這個：
而不是這個： -
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Fragment servicesFrag = bottomNavAdapter.getItem(mainViewPager.getCurrentItem());
if (servicesFrag instanceof ServicesFragment) {
((ServicesFragment) servicesFrag).onActivityResult(requestCode, resultCode, data);
}
}
用這個 ：-
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
for(Fragment fragment : getSupportFragmentManager().getFragments()){
fragment.onActivityResult(requestCode,resultCode,data);
}
}
讓我知道它是否有效

請將此行添加到活動中的 onActivityResult
Fragment servicesFrag = bottomNavAdapter.getItem(mainViewPager.getCurrentItem());
Fragment addressFrag = findFragmentByTag("NewAddressFragmentTag");
if (servicesFrag instanceof ServicesFragment) {
((ServicesFragment) servicesFrag).onActivityResult(requestCode, resultCode, data);
}
if (addressFrag instanceof NewAddressFragment) {
((NewAddressFragment) addressFrag).onActivityResult(requestCode, resultCode, data);
}
}

我可以解決我的問題！
使用以下代碼更改 MainActivity 代碼：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Fragment servicesFrag = bottomNavAdapter.getItem(mainViewPager.getCurrentItem());
Fragment addressFrag = getSupportFragmentManager().findFragmentByTag("NewAddressFragmentTag");
if (servicesFrag instanceof ServicesFragment) {
((ServicesFragment) servicesFrag).onActivityResult(requestCode, resultCode, data);
}
if (addressFrag instanceof NewAddressFragment) {
super.onActivityResult(requestCode, resultCode, data);
}
}
