Android Support-V4 App FragmentTransaction Tips and Tutorial
Introduction
FragmentTransaction is an API in android support-v4 app that allows developers to add, remove, replace, or detach a fragment in an activity. It allows fragments to be managed by the activity dynamically. In this article, we will learn the basics of FragmentTransaction and how to use it to control fragments in your activity.Preparation
Before we begin, you should have basic knowledge of Android development tools like Android Studio, Java programming language, and XML layouts. Also, ensure that you have installed the latest version of Android Support Library in your project.Step 1: Create a New Fragment
First, let’s create a new fragment by right-clicking on the package name in the project explorer and selecting ‘New’ > ‘Fragment’. Give it any preferred name and choose ‘Blank Fragment’. Ensure that you choose AndroidX support library.Step 2: Link the Fragment to Your Activity
The next thing is to link the fragment to your activity. This can be done with the FragmentManager. You can use either FragmentActivity, AppCompatActivity, or any of its derivatives; they all come with FragmentManager.Step 3: Begin the Fragment Management Transaction
To start a fragment management transaction, call `beginTransaction()` method in FragmentManager. This method returns a `FragmentTransaction` object that we can then use to interact with our fragments.Step 4: Add or Replace the Fragment
There are two ways to show a fragment in the activity using FragmentTransaction. We can either add or replace the fragment in our container. The first one is to add and the second one is to replace the fragment. To add a fragment, we use the `add()` method and to replace, we use the `replace()` method of a `FragmentTransaction` object.Step 5: Commit the Transaction
Once we have added or replaced the fragment, we need to call the “commit” method in FragmentTransaction. This will make changes in the fragment manager that controls our fragments.Step 6: Remove or Detach the Fragment
In some cases, we may want to remove or detach a fragment from the activity. For instance, if a user has completed a task on a particular fragment, you can remove it and replace it with another fragment. To remove or detach a fragment, simply call the `remove()` or `detach()` methods in the FragmentTransaction object and commit the changes.Step 7: Set Fragment Transition Animation
We can also set animation when we add, remove, show, or hide a fragment using Android support-v4 app. To set animation, call the `setCustomAnimations()` method in the FragmentTransaction object and pass in the animations resources (both in and out) for fragment transition.Step 8: Handle Fragment Back Stack
When we navigate between fragments, you may encounter problems in preserving fragment states when the back button is pressed. To solve that, we can add each transaction to the back stack by calling the `addToBackStack()` method. When the back button is pressed, it will recall the previous transaction and restore the previous state.Step 9: Find Fragment by ID
In some cases, we may want to find a fragment by ID. To do that, we can call the `findFragmentById()` method in FragmentManager. This method takes the ID of the fragment’s container and returns the fragment instance.Step 10: Communicate between Fragments
Sometimes, two fragments in a single activity need to communicate with each other. To do that, we can send data from one fragment to another using Bundles. The receiver fragment will then retrieve this data and perform the necessary actions.Conclusion
FragmentTransaction is an essential fragment management API that can be used to create dynamic android user interfaces. Following the above tips and tutorial, you should now have a clear understanding of how to use FragmentTransaction in android app development with Android Support-V4 App. With this knowledge, you can build more user-friendly apps that offer a seamless user experience.The Power of Android Support-V4 App Fragmenttransaction
