How to start a fragment from another activity

Question

I want to start a fragment from B activity but the fragment is in main activity. If I use FragmentTransaction, but it gives error "No view found for ID for fragment"

Code

FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.layoutContent, frag);
ft.commit();

Error

No view found for id 0x7f0e00be (com.company.app:id/layoutContent) for fragment PlaylistFrag{5764566 #0 id=0x7f0e00be}

Use inteface or local broadcast and replace fragment in its callback — Mohd Saquib, Aug 16 '17 at 05:37

you are getting error because of the you have not make FrameContainer id as layoutContent — Amit Verma, Aug 16 '17 at 06:02
I am using it as menu item. But one of my activity is not in nav item. So when i switch to fragment from that activity, it gives error. — Ganesh Sumb, Aug 16 '17 at 06:16

If I understand your question, You want to start a fragment in an Activity from another Activity. This is what I do to get Around that.

From the current Activity, I would start the other Activity on Click

Intent intent = new Intent (ActivityA.this, ActivityB.class);
intent.putExtra("EXTRA", "openFragment");
startActivity(intent);

In the destination Activity, listen for intent extras and start action.

switch (getIntent().getStringExtra("EXTRA")){ 
    case "openFragment":
        getSupportFragmentManager().beginTransaction().replace(R.id.replacableLayout, new FragmentActivityB()).commit();
        getSupportActionBar().setTitle("Fragment Activity B");
        break;
}

It works for me...

But, R.id.replacableLayout is only ActivityA not in ActivityB — Mitesh Vanaliya, Jul 26 '18 at 06:42

this will fire an exception as getSupportFragmentManager() is a function with the Activity you work on it so when you use ft.replace(R.id.layoutContent, frag); will look for layoutContent on current activity and will not found

i don't how u want to

Solution ==> - use Event Bus or Rxjava :) or may use a n interface with setter and getter and check it in another activity or use static variable to check the fragment you want to replaced to :)

Add this code in your onClick

// Create new fragment and transaction
Fragment newFragment = new ExampleFragment();
FragmentTransaction transaction = getFragmentManager().beginTransaction();

// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack
transaction.replace(R.id.fragment_container, newFragment);
transaction.addToBackStack(null);

// Commit the transaction
transaction.commit();

and add onBackPressed()

@Override
public void onBackPressed() {
    if (getFragmentManager().getBackStackEntryCount() > 0) {
        getFragmentManager().popBackStack();
    } else {
        super.onBackPressed();
    }
}

You can also use a sections pager adapter to achieve this as in my answer here https://stackoverflow.com/a/55722092/3904109 — DragonFire, Apr 17 '19 at 07:29

Make Layout like below in MainActivity.java and its layout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_add_workout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.nujster.activity.AddWorkoutActivity">

    <LinearLayout
        android:id="@+id/add_workout_fragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal"/>

</RelativeLayout>

Then, in main activity write below code to call fragment

public class AddWorkoutActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_add_workout);

            getSupportFragmentManager().beginTransaction().add(R.id.add_workout_fragment, new LevelFragment(), "levels").addToBackStack(null).commit();
    }

    @Override
    public void onBackPressed() {
        if (getSupportFragmentManager().findFragmentByTag("levels") != null) {
            LevelFragment levelFragment = (LevelFragment) getSupportFragmentManager().findFragmentByTag("levels");
            if (levelFragment.isVisible()){
               finish();
            } else{
                getSupportFragmentManager().popBackStack();
            }
        }
    }
}

@Ganesh Sumb What is your exact problem I didn't get it, please elaborate it. — SWAPDROiD, Aug 16 '17 at 06:59

You can load same fragment in different activities.

Usually Fragment loads in Activity container.

Activity-1 layout have a container say R.id.layoutContent Activity-2 layout also should have a container R.id.xxx

ft.replace(R.id.layoutContent[Container where fragment loads], frag);

May be Activity-2 do not have id of container

Activity 2 doesn't have the container ID. It isn't "maybe" it doesn't – Zoe Aug 16 '17 at 06:39
