Navigation View : Android STUDIO - JAVA

Hello , In this repository you will get to see how to create a NAVIGATION BAR in your app in android studio using Java

STEP 1 : Add dependencies to Gradle Script -> build.gradle -> Module:App-Name.app

dependencies{
 implementation 'com.google.android.material:material:1.0.0'
}

Step 2 :Gradle Sync

STEP 3 : Use Constraint Layout Coordinator Layout and Add BOTTOM Navigation Menu in the text mode of the layout section Code as follows :

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <com.google.android.material.bottomnavigation.BottomNavigationView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/nav_view"
        android:layout_gravity="bottom"
        android:background="#FF5733"
        app:itemIconTint="@color/white"
        app:itemTextColor="@color/white"
        app:menu="@menu/menu_xml_file"
      />
</androidx.coordinatorlayout.widget.CoordinatorLayout>

Step 4 : Create Menu Resource Directory -> menu.xml and put the items according to your need code as follows

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

    <item android:title="Home"
        android:icon="@drawable/ic_baseline_home_24"
        android:id="@+id/home_menu"/>

    <item android:title="Dashboard"
        android:icon="@drawable/ic_baseline_dashboard_24"
        android:id="@+id/dashboard"/>

    <item android:title="Share"
        android:icon="@drawable/ic_baseline_share_24"
        android:id="@+id/share"/>

</menu>

Step 5: Add menu_xml_file to activity_main.xml

Step 6: Go to MainActivity.java and create instance using

private BottomNavigationView bottomNavigationView;

and also assign it with id in onCreate Method:

bottomNavigationView = findViewById(R.id.nav_view);

and then overall code :

package com.aips.navigationview;

import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.MenuItem;
import android.widget.Toast;

import com.google.android.material.bottomnavigation.BottomNavigationView;

public class MainActivity extends AppCompatActivity {
   private BottomNavigationView bottomNavigationView;

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

       bottomNavigationView = findViewById(R.id.nav_view);

       bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
           @Override
           public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
               switch (menuItem.getItemId())
               {
                   case R.id.home_menu:
                       Toast.makeText(MainActivity.this, "You clicked Home icon", Toast.LENGTH_SHORT).show();
                       return true;
                   case R.id.dashboard:
                       Toast.makeText(MainActivity.this, "You clicked  Dashboard icon", Toast.LENGTH_SHORT).show();
                       return true;
                   case R.id.share:
                       Toast.makeText(MainActivity.this, "Your clicked Share icon", Toast.LENGTH_SHORT).show();
                       return true;
                   default:
                       return false;
               }

           }
       });

   }
}
