Why we should use fragment instead of activity?
The fragment is only part of an activity, it basically contributes its UI to that activity. We can’t create multi-screen UI without using fragment in an activity, After using multiple fragments in a single activity, we can create a multi-screen UI.
Why you should use fragments on your Android application?
According to the Android documentation, a fragment is a part of applications user interface that is bound to an activity. Fragments have their lifecycle and layouts or UI components. Fragments help enrich your UI design, pass data between different screens, and adapt to different device configurations.
When should you use a fragment rather than an activity Android?
4 reasons to use Android Fragments
- Dealing with device form-factor differences. The Activity class is often thought of as the main UI class in Android.
- Passing information between app screens.
- User interface organization.
- Advanced UI metaphors.
What are the advantages of using fragment over activity in Android?
Fragments allow such designs without the need for you to manage complex changes to the view hierarchy. By dividing the layout of an activity into fragments, you become able to modify the activity’s appearance at runtime and preserve those changes in a back stack that’s managed by the activity.
Should I always use fragments?
Your life will be a lot easier if you use Fragments when you try to create applications for both phones and tablets. Since the fragments are so tied in with the Honeycomb+ APIs, you will want to use them on phones as well to reuse code. That’s where the compatibility library comes in handy.
Which one is better activity or fragment?
However Fragments also make it possible to have modular UI elements in a single screen. That is a major advantage of Fragments over having a single Activity. Maintaining the back stack of Activity in an Android app is much easier than back stack of multiple fragments.
Why are fragments important?
Fragments are Android’s solution to creating reusable user interfaces. You can achieve some of the same things using activities and layouts (for example by using includes). However; fragments are wired in to the Android API, from HoneyComb, and up.
What are the benefits of fragments?
The Fragment class in Android is used to build dynamic User Interfaces and should be used within the activity. The biggest advantage of using fragments is that it simplifies the task of creating UI for multiple screen sizes. An activity can contain any number of fragments.
Which is better activity or fragment?
“ To put it simply : Use fragment when you have to change the UI components of application to significantly improve app response time. Use activity to launch existing Android resources like video player, browser etc.
Are fragments faster than activities?
I do find fragments a slightly faster than activities but really its not something you would really notice in most cases. Regardless if they was intended for speed or not they still seem/feel little quicker. The downside of using fragments, is certain callbacks like onBackPressed is only in an activity.
What effect does the use of fragments have on the reader?
Use Sentence Fragments Sparingly and When the Story Calls for It. Sentence fragments in fiction can be a useful way of conveying pace, tone, and intensity. However, overuse can lead to lazy writing—fragments should be used sparingly, and for a good storytelling purpose.
What are the major advantages of using fragments for UI implementation?
The main reason is that fragments are more reusable than custom views….And in total they are almost no different with the one big cake.
- When you plate can’t hold a big cake.
- Better re-usability.
- It is, in some sense, a more OO ways of organising your UI logics in Android programming.
Can a fragment be used in more than one activity?
A fragment can be used in multiple activities. The fragment life cycle is closely related to the lifecycle of its host activity. When the activity is paused, all the fragments available in the acivity will also be stopped. A fragment can implement a behavior that has no user interface component.
Why should I care about fragments in large apps?
This is exceedingly important in large apps. If you try to do everything in one Activity with Fragments, you’ll find that there is a certain amount of code you have to add to everything for every Fragment you add after a certain point to keep things flowing smoothly.
What are androidandroid fragments?
Android Fragments eliminate this problem by taking on the UI details and leaving the other responsibilities to the Activity. This way a separate Fragment can be created for each form factor with the form factor specific UI details being the only responsibilities of each Fragment.
What is the use of fragmentpager in Android?
It means back to the previous fragment state. You can use the cool ViewPagerwith a FragmentPagerAdapterto create swipe interfaces. The FragmentPagerAdaptercode is much cleaner than a regular adapter, and it controls instantiations of the individual fragments.
