在我的應(yīng)用程序中，我有一個(gè)activity（MainActivity）和一些fragments（ServicesFragment，NewAddressFragment）。ServicesFragment用于顯示此內(nèi)容viewPager，NewAddressFragment用于顯示！ 在這個(gè)我使用過(guò)，但在其中一個(gè)中的一個(gè)不調(diào)用代碼中發(fā)生沖突。 我寫(xiě)了下面的代碼，請(qǐng)看這個(gè)。主要活動(dòng) ：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(wù)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(diào)用代碼和非調(diào)用代碼中編寫(xiě)onActivityResult代碼時(shí)。MainActivityServicesFragment onActivityResultNewAddressFragment onActivityResult但是當(dāng)刪除onActivityResult代碼時(shí)MainActivity，ServicesFragment 不是調(diào)用 onActivityResult代碼和NewAddressFragment 調(diào)用 onActivityResult代碼。我該如何解決？

在 MainActivity 的 onActivityResult 里面使用這個(gè)：
而不是這個(gè)： -
@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(gè) ：-
@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(qǐng)將此行添加到活動(dòng)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(wèn)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);
}
}
