How to open New Activites by clicking on menu items in bottomnavigation bar - Android Studio

Question

I have searched a lot for this on stackoverflow and on some other professional websites but not found any solution.

I have tried different methods but result was about 0. Some methods work for me but only in that condition when I clicked in top menu navigation bar. But I don't want to show action/top navigation bar.

I only want to show these items in bottomnavigation bar like Recent News, Hot Stories, Most Visited. There are three activities which I want to start by clicking on these items, because my app is a webview app.

For this purpose I am using onOptionItemSelected I think that's wrong. So question goes here >>

I have three buttons in bottom navigation.

1. (action_item1) = on click it should start second_activity

2. (action_item2) = on click it should start third_activity

3. (action_item3) = on click it should start fourth_activity Please help me I am new in android studio.

Navigation XML is here!

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

<item
    android:id="@+id/action_item1"
    android:icon="@drawable/ic_recent"
    android:title="Recent News" />

<item
    android:id="@+id/action_item2"
    android:icon="@drawable/ic_hot"
    android:title="Hot Stories" />

<item
    android:id="@+id/action_item3"
    android:icon="@drawable/ic_most"
    android:title="Most Visited" />
</menu>

        }

From what I have understood, you want to implement Bottom Navigation and open different activities/screens for different items.

I have searched a lot for this on stackoverflow and on some other professional websites but not found any solution.

Everything is not available for copy paste as per your requirement.

I only want to show these items in bottomnavigation bar like Recent News, Hot Stories, Most Visited. There are three activities which I want to start by clicking on these items because my app is a webview app.

To dive into more details refer this tutorial. For your simplicity in this tutiorial Bottom Navigation is implemented through BottomNavigationView provided in android.support.design.widget.BottomNavigationView and fragments are used for different screens as per our requirement.

I want to start by clicking on these items because my app is a webview app.

You can open webview inside these fragments. eg in OnCreate of your fragment you can load webview.
