How to call fragment from an activity in android?
提问by Amrutha
I am working on android fragments. In my app I am getting an issue with activityand fragment. i.e I created a buttonin fragment1and called an activity1in that buttonclick. Again in activity1I created another buttonand called activity2.
Now from activity2I called activity1and from activity1I am trying to call fragment1. But it is showing error at id(can anyone tell me which id we need to give). I researched in google on how to call fragmentfrom activitybut I didnt find any solution for this. Please help me out with this issue. Thanks in advance.

Try this..
尝试这个..
Remove android from this android.R.id.frame_container
从此删除 android android.R.id.frame_container
if you are using activity1extendsActivityuse getFragmentManager()or if you are using activity1extendsFragmentActivityuse getSupportFragmentManager().
如果您正在使用activity1extendsActivityusegetFragmentManager()或者如果您正在使用activity1extendsFragmentActivityuse getSupportFragmentManager()。
like below
像下面
MyFragment1 fragmentS1 = new MyFragment1();
getSupportFragmentManager().beginTransaction().replace(R.id.frame_container, fragmentS1).commit();
回答by Android
Fragment frag;
FragmentManager fm1 = MainActivity.this
.getSupportFragmentManager();
FragmentTransaction ft1 = fm1.beginTransaction();
frag = new Animal_Activity();
ft1.replace(R.id.activity_main_content_fragment, frag);
ft1.commit();

Write it in your activity like below
将其写在您的活动中，如下所示
Fragment fragment = new YourFragment();
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.replace(R.id.output1, fragment);
transaction.addToBackStack(null);
transaction.commit();
回答by Namrata
Do This:-
做这个：-
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager
.beginTransaction();
MyFragment1 fragmentS1 = new MyFragment1();
fragmentTransaction.replace(R.id.realtabcontent, mBarcodeScreen);
fragmentTransaction.commit();
Good Luck !!
祝你好运 ！！
回答by Ramesh R
Simply you can call like this:
只需您可以这样调用：
Fragment fragment = new FragmentName();
FragmentManager fragmentManager = ((Activity) context).getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.fragment_main, fragment).commit();
