Create Tablayout without Viewpager in Android. Tabs in Android with Fragments

Crate Tablayout with Viewpager and fragments :



In this we dont use a Viewpager , due to which we do not get the SLIDING EFFECT.


We use a lsitener on the Tablayout and get the Position of the selected tab using the getPosition() method on tab data passed to the onTabSelected() method.


Then we use fragmentsupportmanager to replace the fragments in the FRAMELAYOUT container.

Activity_main.xml : 


<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

MainActivity.java :



package com.deepesh.tabswithnoviewpagerapp;
import androidx.appcompat.app.AppCompatActivity;

import com.google.android.material.tabs.TabLayout;

public class MainActivity extends AppCompatActivity {

    TabLayout tabLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        tabLayout=findViewById(R.id.tablayout1);

        //register the Listener
        tabLayout.addOnTabSelectedListener(listener);

    }

    //Create Listener
    TabLayout.OnTabSelectedListener listener = new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {

            //getPosition() gives out the Position number or
            // the Rank in which we setup the TabItem in the Tablayout

            if (tab.getPosition()==0){
                calltab1 frag1=new calltab1();
                getSupportFragmentManager().beginTransaction().add(R.id.containerframe,frag1).commit();

                getSupportFragmentManager().beginTransaction().add(R.id.containerframe,frag2).commit();
            }else if (tab.getPosition()==2){
               smstab3 frag3 = new smstab3();
                getSupportFragmentManager().beginTransaction().add(R.id.containerframe,frag3).commit();
            }
        }

        @Override
        public void onTabUnselected(TabLayout.Tab tab) {

        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {

        }
    };

}


EXAMPLE 2 :

(Use "replace" incase of "add" else the fragments are added on top of each other)

React Js + React-Redux (part-2)

Image
  Useful : 1]  Click  2] " Click "  NOTE  :   In the "Reducer" function always have a 'default' switch case,else you'll get Undefined state error. Redux.JS Redux is an open-source state management javascript library.  As the application grows, it becomes difficult to keep it organized and maintain data flow. Redux solves this problem by managing application’s state with a single global object called Store. Redux itself is  a standalone library  that can be used with any UI layer or framework, including React, Angular, Vue, Ember, and vanilla JS. Although Redux and React are commonly used together, they are independent of each other. NOTE  :  The data in react always flows from parent to child components,which makes react  "Unidirectional" . Unlike react,  Angular makes use of bi-directional binding in which the data flow takes place in both directions. What problem does Redux solve  ? So,  state is everywhere in ...

React Js + CSS Styling + React Router (part-1)

Image
Useful : 1] Click  2] Click  3] React Roadmap React is an open source, JavaScript library for developing user interface (UI) in web application. React is developed and released by  Facebook in 2013 . React has a component based architecture i.e everything is a component ,this let you break-down your application into small parts which can then be composed to make complex interfaces. In the past, when browsers were much less capable than today, and JavaScript performance was poor, every page was coming from a server. Every time you clicked something, a new request was made to the server and the browser subsequently loaded the new page. Today, popularized by modern frontend JavaScript frameworks like React, an app is usually built as a single page application: you only load the application code (HTML,  CSS ,  JavaScript ) once, and when you interact with the application, what generally happens is that JavaScript intercepts the browser events and instead of making ...

ViteJS (Module Bundlers, Build Tools)

Image
Module Bundlers ( Useful :1] Click  2] Click ) Web browsers can only understand and execute JavaScript, HTML and CSS . However, developers often use other technologies and tools like React, Sass, TypeScript, and Tailwind to improve the development process, write more maintainable code, and add additional functionality to their applications. We need a way to combine all this JS & CSS code into a single optimized javascript file, this is achieved through module bundling. A module bundler is a tool that takes all the JavaScript files in a project and combines them into a single JS file (or a few files) that can be loaded by a browser. It usually starts with an entry point file, and from there it will start looking for "import" statements and then bundles up all of code needed for that entry file. The entry point is typically defined in the config file of the bundler. The entry point is the file where the bundler starts its traversal of the application's dependencies...
