导航到先前的片段而无需重新加载 [英] Navigating to previous fragment without reloading it

问题描述

我正在创建一个正在使用片段的应用程序.我想从另一个片段返回到先前的片段，而无需重新加载先前的片段.

I am creating an app in which I'm using fragments. I want to go back to the previous fragment from another fragment without reloading the previous fragment.

转到下一个片段的代码:

Code for going to the next fragment:

Fragment newFragment;
android.support.v4.app.FragmentManager manager = ((AppCompatActivity) context).getSupportFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
newFragment = new Inner_details();
transaction.replace(R.id.content_data, newFragment);

transaction.addToBackStack("fragment6");

transaction.commit();

转到上一个片段的代码

FragmentManager fm = getActivity().getSupportFragmentManager();

fm.popBackStack ("fragment6", FragmentManager.POP_BACK_STACK_INCLUSIVE);

推荐答案

您正在替换片段，因此先前的片段将不再具有其内容，您可以尝试通过添加"而不是替换"加载片段:

you are replacing your fragments so the previous fragment will no longer be available with its content, you might try to load your fragments by "add" instead of "replace":

 transaction.add(R.id.content_data, newFragment);
