How to move from one fragment to another fragment on click of an ImageView in Android?

Question

I have an ImageView. I want to move from one fragment to another fragment on a click of an Imageview, the same way like we can move from one activity to another using

Intent i=new Intent(MainActivity.this,SecondActivity.class);
startActivity(i);

How can I do this? Can anyone explain to me step by step?

My codes are as follows:

mycontacts.class

public class mycontacts extends Fragment {
    public mycontacts() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
        final View v = super.getView(position, convertView, parent);
        ImageView purple=(ImageView)v.findViewById(R.id.imageView1);
        purple.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
            // TODO Auto-generated method stub
            //how to go to tasks fragment from here???
            }
        });
        return view;

    } 
}

tasks.class

public class tasks extends Fragment {
    public tasks() { 
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.fragment_layout_one, container,
            false);

        return view;
    }
}

Answer 1

purple.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        Fragment fragment = new tasks();
        FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(R.id.content_frame, fragment);
        fragmentTransaction.addToBackStack(null);
        fragmentTransaction.commit();
    }
});

You write the above code...there we are replacing R.id.content_frame with our fragment.

Answer 2

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_profile, container, false);
    notification = (ImageView)v.findViewById(R.id.notification);

    notification.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            FragmentTransaction fr = getFragmentManager().beginTransaction();
            fr.replace(R.id.container,new NotificationFragment());
            fr.commit();
        }
    });

    return v;
}

Answer 3

Add this code where you want to click and load Fragment.

Fragment fragment = new yourfragment();
        FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(R.id.fragment_container, fragment);
        fragmentTransaction.addToBackStack(null);
        fragmentTransaction.commit();

Answer 4

When you are inside an activity and need to go to a fragment use below

getFragmentManager().beginTransaction().replace(R.id.*TO_BE_REPLACED_LAYOUT_ID*, new tasks()).commit();

But when you are inside a fragment and need to go to a fragment then just add a getActivity(). before, so it would become

getActivity().getFragmentManager().beginTransaction().replace(R.id.*TO_BE_REPLACED_LAYOUT_ID*, new tasks()).commit();

as simple as that.

The *TO_BE_REPLACED_LAYOUT_ID* can be the entire page of activity or a part of it, just make sure to put an id to the layout to be replaced. It is general practice to put the replaceable layout in a FrameLayout .

Answer 5

inside your onClickListener.onClick, put

getFragmentManager().beginTransaction().replace(R.id.container, new tasks()).commit();

In another word, in your mycontacts.class

public class mycontacts extends Fragment {

    public mycontacts() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        final View v = super.getView(position, convertView, parent);
        ImageView purple = (ImageView) v.findViewById(R.id.imageView1);
        purple.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                getFragmentManager()
                        .beginTransaction()
                        .replace(R.id.container, new tasks())
                        .commit();
            }
        });
        return view;

    }
}

now, remember R.id.container is the container (FrameLayout or other layouts) for the activity that calls the fragment

Answer 6

You can move to another fragment by using the FragmentManager transactions. Fragment can not be called like activities,. Fragments exists on the existence of activities.

You can call another fragment by writing the code below:

FragmentTransaction t = this.getFragmentManager().beginTransaction();
Fragment mFrag = new MyFragment();
t.replace(R.id.content_frame, mFrag);
t.commit();

here "R.id.content_frame" is the id of the layout on which you want to replace the fragment.

You can also add the other fragment incase of replace.

Answer 7

If you're looking for the Kotlin version of the above code, you can do it in this way, and you call replaceFragment(RequiredFragment()) at onClickListener or wherever you want.

private fun replaceFragment(fragment: Fragment) {
val transaction = activity!!.supportFragmentManager.beginTransaction()
transaction.replace(R.id.frame, fragment)
transaction.commit()
}

Answer 8

private boolean loadFragment(Fragment fragment) {
        if (fragment != null) {
            getSupportFragmentManager()
                    .beginTransaction()
                    .replace(R.id.fl_fragment_container, fragment)
                    .commit();
            return true;
        }
        return false;
    }

Answer 9

in kotlin, put inside of your current running fragment button.setOnClickListener

    val bpfragment = TwoFragment()
    activity?.supportFragmentManager?.beginTransaction()?.replace(R.id.fragment_container, bpfragment)?.commit()

Answer 10

            val fragment = YourFragment3()
            val fm : FragmentManager= requireActivity().supportFragmentManager
            val ft: FragmentTransaction = fm.beginTransaction()
            ft.replace(R.id.container, fragment)
            ft.commit()
            (activity as MainActivity).binding.viewPager.setCurrentItem(2)
