I want to add an explode transition in my next fragment using the latest Navigation pattern "Navigation Graph".How to add a transition XML file(#transition/fade or #transition/slide or #transiton/explode) into Navigation Graph of android app.
You will probably want to define the desired transition in your navigation graph like this:
<fragment
// here your fragment is defined
<action
android:id="#+id/your_action_id"
app:destination="#id/yourDestinationFragment"
app:enterAnim="#anim/fade_in"
app:exitAnim="#anim/fade_out"
app:popEnterAnim="#anim/fade_in"
app:popExitAnim="#anim/fade_out" />
</fragment>
Note that you can define different animations for entering and leaving a fragment.
The animations you define will go into the /res/anim folder. You might have to create it if you don't find it.

When I add the View Host Fragment, the design becomes invisible in the xml section, what can I do?
While navigating in Android Studio, when I add nav host fragment to the xml part, the design side becomes invisible, what can I do?
If you encounter such a problem, do not forget to give tools to the xml side in the navigation section, and do not forget to set the constrait to the nav host.
Navigation xml into
xmlns:tools="http://schemas.android.com/tools"
For example
<fragment
android:id="#+id/firstfragment"
android:name="com.example.countryapps.firstfragment"
tools:layout="#layout/fragment_firstfragment"
android:label="firstfragment" >
<action
android:id="#+id/action_firstfragment_to_secondfragment"
app:destination="#id/secondfragment" />
</fragment>
I have a fragment in bottom navigation when try to launch new fragment with same id using navigation controller instead of launching new fragment it redirects me to bottom navigation tab.
here is my code
<navigation 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/home_navigation"
app:startDestination="#id/splashFragment">
<fragment
android:id="#+id/baseTabsFragment"
android:name="com.abc.abc.fragment.BaseTabsFragment"
android:label="BaseTabsFragment"
tools:layout="#layout/fragment_common_tabs">
<action
android:id="#+id/action_to_baseFragment"
app:destination="#id/baseTabsFragment"
app:launchSingleTop="false" />
</fragment>
</navigation>
And code to navigate.
findNavController().navigate(R.id.action_to_baseFragment)
Here is a link for more details on this

Update: I want to avoid the code duplication. I will have same fragments with same actions but different id's looking for a better way to do it.
If i understand correctly, you want to navigate to the same fragment and fragment does not refresh.
If you use navigation component in visual interface you need to pull an arrow from your baseFragment onto baseFragment again, with this you will see an arrow like self pointed. If you don't use visual just paste below code and it will be created.
<action
android:id="#+id/action_to_BaseFragment"
app:destination="#id/baseTabsFragment"
app:popUpTo="#id/baseTabsFragment"
app:popUpToInclusive="true" />
We are using this way because if we want system to navigate, it needs different location then previous, as long as we using same fragment we need to pop the old one.
It happened due to bottom menu. In this case you need to call programmatically to click on that bottom button.
Replace
findNavController().navigate(R.id.action_to_baseFragment)
to
navController.navigate(
R.id.base_graph, null,
NavOptions.Builder().setPopUpTo(navController.graph.startDestinationId, true).build()
)
I'm using navigation component
'androidx.navigation:navigation-fragment-ktx:2.3.3'
'androidx.navigation:navigation-ui-ktx:2.3.3'
I don't understand why when I'm navigating from my startDestination to the next Fragment
I get a short blinking and I see the previous activity for a couple of millisec.
This doesn't happen when I'm navigating to different fragments.
This happens with and without the navigation animations.
Tried with no previous Activity in stack and it shows the OS home screen.
The navigation.xml file looks like this:
<fragment
android:id="#+id/barcodeScannerFragment"
android:name="com.sightplan.sightplanmobile.feature.barcode_scanner.BarcodeScannerFragment"
android:label="#string/receive_package_barcode_input_view_header_param_title"
tools:layout="#layout/barcode_scanner_fragment_layout">
<action
android:id="#+id/open_receive_package_details"
app:destination="#id/receivePackageDetailsFragment"
app:enterAnim="#anim/slide_left_anim"
app:exitAnim="#anim/wait_anim"
app:popEnterAnim="#anim/wait_anim"
app:popExitAnim="#anim/slide_right_anim" />
</fragment>
<fragment
android:id="#+id/receivePackageDetailsFragment"
android:name="com.sightplan.sightplanmobile.packages.receive_package.ReceivePackageDetailsFragment"
android:label="#string/receive_package_activity_on_create_header_bar_title"
tools:layout="#layout/receive_package_details_fragment_layout">
.......
The navigation (full) desgin looks like this:
And the code for navigating from the startDestination to the Receive Package screen is here:
val action = BarcodeScannerFragmentDirections.openReceivePackageDetails()
Navigation.findNavController(it).navigate(action)
Any ideas on how to solve this?
The problem was due to the theme set on my navigation Activity inside the AndroidManifest.xml.
I had a custom AppTheme with android:windowIsTranslucent set to true.
Removing that solved the issue.
I based my code on this question : How to create BottomSheetDialogFragment using Navigation Architecture Component?
I want to use fragment bottom sheet with navigation component I used the following setup :
<fragment
android:id="#+id/mainFragment"
android:name="package.MainFragment"
android:label="main_fragment"
tools:layout="#layout/main_fragment" >
<action
android:id="#+id/action_mainFragment_to_bottomSheet"
app:destination="#id/bottomSheet" />
</fragment>
<dialog
android:id="#+id/bottomShee"
android:name="package.OptionFragment" />
and in the code
view.findNavController().navigate(R.id.action_mainFragment_to_bottomSheet)
But the problem is that the bottom sheet appears in another fragment and not shadowing current fragment.
is there any way to implement bottom sheet with android navigation component?
Your bottom sheet fragment needs to inherit from: BottomSheetDialogFragment() and not Fragment()
How to add animation to changing fragments using Navigation Architecture Component?
In the Navigation Component documentation(https://developer.android.com/topic/libraries/architecture/navigation/navigation-implementing) in the section: Create a transition between destinations (it's near the end of the document) you have it explained in detail.
You can either add them using the editor by selecting the arrow of the desired transition and then selecting the animations in the Animations section of the Attributes tab.
Or by referencing the animations in the xml file like in the example:
<fragment
android:id="#+id/specifyAmountFragment"
android:name="com.example.buybuddy.buybuddy.SpecifyAmountFragment"
android:label="fragment_specify_amount"
tools:layout="#layout/fragment_specify_amount">
<action
android:id="#+id/confirmationAction"
app:destination="#id/confirmationFragment"
app:enterAnim="#anim/slide_in_right"
app:exitAnim="#anim/slide_out_left"
app:popEnterAnim="#anim/slide_in_left"
app:popExitAnim="#anim/slide_out_right" />
</fragment>
You can use regular anim resources for this animations
If you want to add animation through programmatically, use NavOptions (here).
NavOptions.Builder navBuilder = new NavOptions.Builder();
navBuilder.setEnterAnim(R.anim.slide_left).setExitAnim(R.anim.slide_right).setPopEnterAnim(R.anim.slide_left).setPopExitAnim(R.anim.slide_right);
//Inside Activity
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
navController.navigate(R.id.destinationFragmentId,null,navBuilder.build());
//Inside Fragment
NavHostFragment.findNavController(YoutFragment.this)
.navigate(R.id.destinationFragmentId, null, navBuilder.build());
