Android refresh all views

Android swipe to refresh view || Pull down refresh

Every app needs to fetch data on user interaction that may be using a refresh button or may be a swipe to refresh view or pull down to refresh view. In this blog we can get through Android swipe to refresh view tutorial.

In almost every app like youtube, facebook, twitter, instagram, gmail, yahoo and many more apps not only social media but also in news related apps where there is option to refresh we can find this view.

Swipe to refresh view is not used only for list views but also for updating all the components present on the screen.

In general we use android phone, there to answer a call or reject we use the same swipe to refresh view.Now a days to delete a row in list view and undo them also we use.

In this tutorial i will be using api which will be parsing dynamic results.

All the data, information, images got from

Add required dependencies before getting started also make sure you are providing latest versions to avoid abnormal crashes in app due to deprecated codes.

activity_main.xml

Add a swipe to refresh view to the layout this is the key aspect of this tutorial

We are making a simple view by use of multiple textviews and a imageview to show user details in real time usage you may use accordingly.

MainActivity.java

Initialize all the views in oncreate using init() method. Here you may also refer to databinding which is the fastest way to fetch the bind the UI components to the screen.

Fetch data using retrofit library here we have onResponse and onFailure states for handling the result.

In onSuccess store the data to the respective data model class User and populate it using swipe to refresh view.

In onFailure show a toast stating the reason.

Set the image to the views using glide for image view in realtime you may use a for loop to parse the data and set it to the views

AndroidManifest.xml

Add Internet permission to manifest file

Output :

This screen depicts the on swipe to refresh view

Pull to Refresh with RecyclerView in Android with Example

The SwipeRefreshLayout widget is used for implementing a swipe-to-refresh user interface design pattern. Where the user uses the vertical swipe gesture to refresh the content of the views. The vertical swipe is detected by the SwipeRefreshLayout widget and it displays a distinct progress bar and triggers the callback methods in the app. In order to use this behavior, we need to use the SwipeRefreshLayout widget as the parent of a ListView or GridView. These Material Design UI Patterns are seen in applications like Gmail, Youtube, Facebook, Instagram, etc. It allows the user to refresh the application manually. SwipeRefreshLayout class contains a listener called OnRefreshListener. The classes which want to use this listener should implement SwipeRefreshLayout.OnRefreshListener interface. On vertical swipe-down gesture, this listener is triggered and onRefresh() method is called and can be overridden according to the needs.

Example

In this example, we would store data into the ArrayList which is used for populating the RecyclerView. Whenever onRefresh() method is called the ArrayList data gets rearranged. A sample GIF is given below to get an idea about what we are going to do in this article. Note that we are going to implement this project using the Java language.

Step by Step Implementation

Step 1: Create a New Project

To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Java as the programming language.

Step 2: Adding dependencies

Pull To Refresh Views for Android Renewal ! v3.2

This project is a fork of Chris Banes’ Android-PullToRefresh project. The project provides flexibility in customization in addition to adding brand new features listed below.

New! AAR package support

Google-like pull to refresh animation support (in Android 3.x or 4.x)

NOTE: This style is now supported in Android Support Library. I recommend you to use the support library instead of this library, unless you are already using and want to change the style from old style to it.

Easy layout customization — no need to include the library’s source code directly into your project.

Easily Customizable loading layouts, labels, and icons.

Ability to customize and add multiple indicator layouts.

Configurable friction and smooth scroll duration.

This fork project is not being deprecated. Please send issues or pull requests to me, and I will provide you with feedbacks.

Are you are using Pull To Refresh v2.1.x? You’d better MIGRATE to v3.2 now!

This project aims to provide a reusable Pull to Refresh widget for Android. It was originally based on Johan Nilsson’s library (mainly for graphics, strings and animations), but these have been replaced since.

• Supports both Pulling Down from the top, and Pulling Up from the bottom (or even both).
• Animated Scrolling for all devices.
• Over Scroll supports for devices on Android v2.3+.
• Currently works with:
  • ListView
  • ExpandableListView
  • GridView
  • WebView
  • ScrollView
  • HorizontalScrollView
  • ViewPager
• Integrated End of List Listener for use of detecting when the user has scrolled to the bottom.
• Maven Central Support.
• Indicators to show the user when a Pull-to-Refresh is available.
• Support for ListFragment!
• Lots of Customization options!

Sample application is being provided as APK file (the source is in the repository):

To begin using the library, please see the Quick Start Guide.

Our Customization page contains detailed information on how to change the behaviour and look of the View.

Pull Up to Refresh

By default this library is set to Pull Down to Refresh, but if you want to allow Pull Up to Refresh then you can do so. You can even set the View to enable both Pull Up and Pull Down using the ‘both’ setting. See the Customization page for more information on how to set this.

Want to see which Apps are already using Android-PullToRefresh? Have a look here.

Please see the new Changelog page to see what’s recently changed.

I will gladly accept pull requests for fixes and feature enhancements but please do them in the dev branch. The master branch is for the latest stable code, dev is where I try things out before releasing them as stable. Any pull requests that are against master from now on will be closed asking for you to do another pull against dev.

Implementing Pull to Refresh Guide

In Android, the common «pull to refresh» UX concept is not built in to a ListView/RecyclerView. However, many Android applications would like to make use of this concept for their feeds. This is useful for all sorts of feeds such as a Twitter timeline. This effect can be achieved using the SwipeRefreshLayout class

SwipeRefreshLayout is a ViewGroup that can hold only one scrollable view as a child. This can be either a ScrollView or an AdapterView such as a ListView or a RecyclerView .

Edit your app/build.gradle file to include a library:

Make sure your libraries is up to date by adding to your root gradle.file :

Just like the previous section, wrap the scrollable view, in this case a RecyclerView with a SwipeRefreshLayout in the XML layout:

Make sure to have helper methods in your RecyclerView adapter to clear items from the underlying dataset or add items to it.

Next, we need to configure the SwipeRefreshLayout during view initialization in the activity. The activity that instantiates SwipeRefreshLayout should add an OnRefreshListener to be notified whenever the swipe to refresh gesture is completed.

The SwipeRefreshLayout will notify the listener each and every time the gesture is completed again; the listener is responsible for correctly determining when to actually initiate a refresh of its content.

Next, we need to configure the SwipeRefreshLayout during view initialization in the activity:

Note that upon successful reload, we must also signal that the refresh has completed by calling setRefreshing(false) . Also note that you should clear out old items before appending the new ones during a refresh.

If you are using SwipeRefreshLayout with Android’s new Paging Library, the data sources used to provide data to the RecyclerView need to be invalidated. Review this guide for more information.

Note: ListView is an old UI component that is no longer used in modern Android applications. Only refer this guide if you intend to update some old code that still relies on ListView.

Set SwipeRefreshLayout at the Layout you want the SwipeRefresh functionality

activity_main.xml

activity_main.xml

You could use a ScrollView instead a ListView

In the activity who points to activity_main.xml, which is main_activity(in this example), this code should be enough

main_activity.java

Now just run your application!

You could check this example on GitHub.

If you aren’t able to get the swipe to refresh working, check the following tips:

Did you accidentally call setContentView twice? Ensure that inside your activity, you’ve only called setContentView once as the 2nd line of your onCreate method.

Did you invoke setRefreshing(false) after data finished loading? With the swipe to refresh control, you are responsible for notifying the system once the new data has been loaded into the list. You must make sure to invoke setRefreshing only after the data has come back and not before. This means if you are loading data from the network, calling this within the onSuccess method.

Did you clear out the old items before updating the list? Make sure that in order for the new items to be displayed that you clear the list of any old items if needed. In other words, if you are replacing items in the list with new versions, be sure to remove the old versions from the adapter first with adapter.clear();

Are you using CoordinatorLayout? If you are using a CoordinatorLayout to manage scrolling, be sure to move the app:layout_behavior=»@string/appbar_scrolling_view_behavior» property to the SwipeRefreshLayout rather than the child RecyclerView or ListView .

SwipeRefreshLayout With NestedScrollView — Android

Refresh you View Content with SwipeRefreshLayout

Aug 26, 2019 · 2 min read

Introduction:

In Android we have SwipeRefreshLayout, we often used this in our layouts to refresh the content of a view with the vertical gesture feature, whenever we need it. The SwipeRefreshLayout can only support direct one child only, so whenever we need to add in our layout, we always try to add before our RecyclerView like this below code snippet:

Recently I have been working in an Application where I have a RecyclerView with CoolapingToolbar and NestedScrollView , and I need to add a SwipeRefreshLayout , so I just Implemented the way it looked above simply put the SwipRefreshLayout above the RecyclerView .

A f ter that, I just run the application and guess what, nothing happened and the data was not showing in the list, so then I figured it out what’s goes wrong in the Implementation.

How to Solve:

The solution is very simple, We need to add a SwipRefreshLayout above the NestedScrollView and So you should move app:layout_behavior=»@string/appbar_scrolling_view_behavior» from NestedScrollView to SwipeRefreshLayout .

That’s it just runs your application and sees the results.

Let’s see with the XML File.

Conclusion:

This article described you how to Implement the SwipeRefreshLayoyut with NestedScrollView, hows the Implementation is different from the traditional one.

I hope this article is helpful. If you think something is missing, have questions, or would like to give feedback, go ahead and leave a comment below. I’d appreciate the feedback.

I’ve written some other Android-related content, and if you liked what you read here, you’ll probably also enjoy this:
