For Fragment Reload // Reload current fragment Fragment frg = null; frg = getSupportFragmentManager().findFragmentByTag("Your_Fragment_TAG"); final FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); ft.detach(frg); ft.attach(frg); ft.commit(); Your_Fragment_TAG is the name you gave your fragment when you created it This code is for support library. If you're not supporting older devices, just use getFragmentManager instead of getSupportFragmentManager For Activity Reload Intent i = new Intent(MainActivity.this, MainActivity.class); finish(); overridePendingTrans ..read more

To start building your Node.js applications, the first step is the installation of the node.js framework. The Node.js framework is available for a variety of operating systems right from Windows to Ubuntu and OS X. Once the Node.js framework is installed you can start building your first Node.js applications. Node.js also has the ability to embedded external functionality or extended functionality by making use of custom modules. These modules have to be installed separately. An example of a module is the MongoDB module which allows you to work with MongoDB databases from your Node.js ..read more

ConstraintLayout allows you to create large and complex layouts with a flat view hierarchy (no nested view groups). It's similar to RelativeLayout in that all views are laid out according to relationships between sibling views and the parent layout, but it's more flexible than RelativeLayout and easier to use with Android Studio's Layout Editor. All the power of ConstraintLayout is available directly from the Layout Editor's visual tools, because the layout API and the Layout Editor were specially built for each other. So you can build your layout with ConstraintLayout entirely by drag-and ..read more

A layout defines the structure for a user interface in your app, such as in an activity. All elements in the layout are built using a hierarchy of View and ViewGroup objects. A View usually draws something the user can see and interact with. Whereas a ViewGroup is an invisible container that defines the layout structure for View and other ViewGroup objects, as shown in figure 1. Figure 1. Illustration of a view hierarchy, which defines a UI layout The View objects are usually called "widgets" and can be one of many subclasses, such as Button or TextView. The ViewGroup objects are usually call ..read more

LinearLayout is a view group that aligns all children in a single direction, vertically or horizontally. You can specify the layout direction with the android:orientation attribute. Note:For better performance and tooling support, you should instead build your layout with ConstraintLayout. All children of a LinearLayout are stacked one after the other, so a vertical list will only have one child per row, no matter how wide they are, and a horizontal list will only be one row high (the height of the tallest child, plus padding). A LinearLayout respects margins between children and the gravity ..read more

If you want to deliver a web application (or just a web page) as a part of a client application, you can do it using WebView. The WebView class is an extension of Android's View class that allows you to display web pages as a part of your activity layout. It does not include any features of a fully developed web browser, such as navigation controls or an address bar. All that WebViewdoes, by default, is show a web page. A common scenario in which using WebView is helpful is when you want to provide information in your app that you might need to update, such as an end-user agreement or a user ..read more

RelativeLayout is a view group that displays child views in relative positions. The position of each view can be specified as relative to sibling elements (such as to the left-of or below another view) or in positions relative to the parent RelativeLayout area (such as aligned to the bottom, left or center). Note:For better performance and tooling support, you should instead build your layout with ConstraintLayout. A RelativeLayout is a very powerful utility for designing a user interface because it can eliminate nested view groups and keep your layout hierarchy flat, which improves performan ..read more

Last month at Google I/O we talked about what’s new for Android developers, from new features in Android Q to the latest in Kotlin and Jetpack. With Android Q, we highlighted three themes: innovation, security and privacy, and digital wellbeing. We want to help you take advantage of the latest new technology -- 5G, foldables, edge-to-edge screens, on-device machine learning, and more -- while making sure users' security, privacy, and wellbeing are always a top priority. We also talked about how we’re going increasingly Kotlin-first, and continuing to expand Jetpack with new librari ..read more

The best way to learn is to read and that’s true for a developer as well. If you want to become a better developer, you have to read more code. It’s as simple as that.Books, blogs, forums are all good to a certain extent but there is nothing that can replace some fully-functional, exhaustive open-source projects where the entire app with all its resources is right in front of you.All you have to do is sit back, take a cup of coffee and read some kick-ass code.
