Navigating to a destination is done using a NavController, an object that manages app navigation within a NavHost.Each NavHost has its own corresponding NavController.NavController provides a few different ways to navigate to a destination, which are further described in the sections below..

Step 3 − Add the following code to src/MainActivity. Android Studio kept recommending that I use FragmentContainerView instead of a Fragment in my layout file for most of this year. The problem is that I could never get things to work properly, so I kept using the <fragment> tag in my main Activity's layout file, activity_main.xml.Until now, thanks to some Android Developer docs being updated recently

Using Fragments with the Navigation Drawer Activit

Since your fragments live under an Activity, it's common to use one shared ViewModel for the Activity and its associated fragments.

  2. If we use Single Activity Architecture, the sharing of the data happens in the Fragments level and all of the Fragments are wrapped inside the Activity. Doing this keeps the shared data away from other elements in the Application Scope which means it cannot be accessed by Service or Content Provider. 4
  3. The first row will find the NavController, which is the base class for Navigation Component to navigate to the destinations in our app. The second row will navigate us to the dialog fragment using the action, what we have created in the navigation graph

We will first look at how to provide up navigation in an application. Providing Up Navigation. The up navigation will allow our application to move to previous activity from the next activity. It can be done like this After creating fragments, we can now define a direction of navigation (i.e. from where navigation should start to where it should end). At this stage, it is also important to know about the concepts of destinations, arguments, and actions. A destination is a tag used to define the direction of navigation (e.g. the start destination is the first screen that the user will see when the app is. 重新設計Navigation Graph. 剛剛新增的main_navigation.xml是為Activity設計的,我們現在要把它修改為以Fragment為基底. 新增兩個Fragment: AFragment和BFragment. 然後在.

Drawer layout. val drawerLayout: DrawerLayout = findViewById(R.id.drawer_layout b) The single Activity tends to become a sort of God class. When all navigation occurs in the one Activity, that Activity needs to know about every scene in the app. c) By passing a single navigation management interface, all Fragments gain the power to navigate anywhere in the app. This might not be desirable

  4. In this example, we're expecting that the target fragment is an instance of DisplayNameFragment. My first instinct was to write a basic/generic way of handling this, but I've decided not to over engineer it. When a name is entered, we pass that result back to the DisplayNameFragment by calling setName(), and then telling the activity to pop this fragment off the top, which will then reshow our.

The Navigation Architecture component is a part of the new AndroidX package that's introduced since Android SDK 28. This component consists of new guidelines to structure your application, especially navigation between Fragments. Google recommends the Single Activity Architecture moving forward when using JetPack In its body, we list all fragments attached to activity and for this implementing our BaseFragment class/interface we notify them about the new back-press event. The notified fragment can indicate event consumption by returning true, in this case, we stop iterating and leave the method But fragments do not get notified of a back press event. Suppose an Activity has a stack of 3 fragments. For a regular android user, normal expectation upon a back press would be to navigate back through the fragments Fragment that needs to handle backPressed () event. The method: Logic to handle when backPress is clicked in SearchFragment. 3-Now it's the time to connect the dots and override the Activity's OnBackPressed () function to implement the logic, We needed to get the current fragment from fragmentManager and examine if it was of type. The Navigation Drawer; The Toolbar; And, the Back Button but also recognise the convenience of being able to add fragments to the backstack from both the activity and a fragment. And sticking to the DRY principle means that I can't put the logic into both the BaseActivity and BaseFragment so I just abstracted it out into a new class.

You are spot on with code, just make few corrections and finsih your current activity. requireActivity () will return the FragmentActivity this fragment is currently associated with. while activity? might return null if the fragment is associated with a Context instead. so, you might never get inside the navigation code For passing data from activity to fragment you can follow some steps given below: Bundle - Bundle is a mapping from String values to various Parcelable types. bundle syntax.

My bad (i am a confused person ) so suppose FragmentVue1 is your activity's name and you want to open it on clicking nth item of navigation drawer us The presenter takes in the fragment mapping and a view model loader as dependencies, which can be used later during navigation to inflate the proper fragments. Now, this next part is the one thing here that feels somewhat dirty, but its scope is pretty limited. Since the container activity is what is going to be started initially, we'll make it. Produce fragment result, to pass data to the destination. That's it, the destination fragment will receive the result and execute listener callback once it's STARTED..
