How to Transfer from One Fragment to Another in Android

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

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.

How to move from one fragment to another fragment on button's click in android?

Use Fragment transaction to replace your second fragment with third fragment on button click,
For example,

Fragment thirdFragment = new ThirdFragment();
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.fragment_container, thirdFragment);
transaction.addToBackStack(null);
transaction.commit();

Hope it helps!

How to transfer data from one Fragment to another?

To pass data between two fragments with jetpack navigation you have to use Safe Args

pass an argument section like

 <fragment android:id="@+id/myFragment" >
     <argument
         android:name="myArg"
         app:argType="integer"
         android:defaultValue="0" />
 </fragment>

add classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version" in top level gradle file

and add the plugin apply plugin: "androidx.navigation.safeargs.kotlin"
now send the value like so

override fun onClick(v: View) {
   val amountTv: EditText = view!!.findViewById(R.id.editTextAmount)
   val amount = amountTv.text.toString().toInt()
   val action = SpecifyAmountFragmentDirections.confirmationAction(amount)
   v.findNavController().navigate(action)
}

and receive it as

val args: ConfirmationFragmentArgs by navArgs()

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    val tv: TextView = view.findViewById(R.id.textViewAmount)
    val amount = args.amount
    tv.text = amount.toString()
}

However safeargs works only for primitive types so you have to deconstruct and reconstruct if you're trying to pass Objects

How to transfer some data to another Fragment?

Use a Bundle. Here's an example:

Fragment fragment = new Fragment();
Bundle bundle = new Bundle();
bundle.putInt(key, value);
fragment.setArguments(bundle);

Bundle has put methods for lots of data types. See this

Then in your Fragment, retrieve the data (e.g. in onCreate() method) with:

Bundle bundle = this.getArguments();
if (bundle != null) {
        int myInt = bundle.getInt(key, defaultValue);
}

how to switch from one fragment to another fragment android

You can pop the fragment by name. While adding fragments to the back stack, just give them a name.

fragmentTransaction.addToBackStack("frag2");

Then in fragment5, pop the back stack using the name ie.. frag2 and include POP_BACK_STACK_INCLUSIVE

    someButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            FragmentManager fm = getActivity()
                    .getSupportFragmentManager();
            fm.popBackStack ("frag2", FragmentManager.POP_BACK_STACK_INCLUSIVE);
        }
    });
