React native bottom tab bar pushing itself up when opening keyboard

Question

We are using createBottomTabNavigator. In one of the tab contains search bar at the top. While clicking on that search bar, we are opening the keyboard. But the keyboard pushing up the bottom tab bar also. We need the bottom tab bar remains at the bottom when opening keyboard.

1. One of the solution I have tried is, in android manifest, I have changed android:windowSoftInputMode="adjustPan" or "adjustNothing". It is working fine as expected. But we are using chat layout in another tab which needs "adjustResize". So I have to keep "adjustResize" for windowSoftInputMode.
2. As another solution, I tried to change windowSoftInputMode inside component itself. SO I have tried with this - https://www.npmjs.com/package/react-native-android-keyboard-adjust. But no use.
3. As another one, I tried to create a TabBarComponent like mentioned here https://github.com/react-navigation/react-navigation/issues/618. But not working as expected.

const SignedIn = createBottomTabNavigator(
  {
    Followers: {
      screen: FollowerStack,
      ...
    },
    Search: {
      screen: SearchStack,
    },
    Home: {
      screen: HomeStack,
    },
    Bookmarks: {
      screen: BookmarkStack,
    },
    Profile: {
      screen: ProfileStack,
    }
  },
  {
    initialRouteName: "Home",
    tabBarPosition: 'bottom',
    swipeEnabled: false,
    animationEnabled: false,
    tabBarOptions: {
      keyboardHidesTabBar: true,
      showIcon: true,
      showLabel: false,
      activeTintColor: "red",
      inactiveTintColor: "gray",
      adaptive: true,
      safeAreaInset: {
        bottom: "always"
      },
      style: {
        position: 'relative',
        backgroundColor: "#F9F8FB",
        height: TAB_NAVIGATOR_DYNAMIC_HEIGHT,
        paddingTop: DeviceInfo.hasNotch() ? "5%" : "0%",
        minHeight: TAB_NAVIGATOR_DYNAMIC_HEIGHT,
        width: '100%',
        bottom: 0
      }
    }
  }
);

1. Is there any other properties existed for making the bottom tab bar sticky at the bottom? or
2. Is it possible to change the android manifest windowSoftInputMode from inside component? Please comment below if you required any other code part for reference. Thanks for any help.

Answer 1

I used React navigation 5, is this what you want?

<SignedIn.Navigator 
   tabBarOptions={{
      keyboardHidesTabBar: true
   }}         
}>
</SignedIn.Navigator>

The document to read here.

Answer 2

Just go to AndroidManifest.xml file and change/add inside activity tag:

android:windowSoftInputMode="adjustPan"

Answer 3

Please use this on

<Tab.Navigator
screenOptions={{
    tabBarHideOnKeyboard: true
 }}
/>

I am sure it will work perfectly

Answer 4

Found it, just add your bottom navigation into a view making that view of dimensions of the screen, this way:

import React from 'react'
import { StyleSheet, Text, View, Dimensions } from 'react-native'
import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';

const { width, height } = Dimensions.get("window")
const Tab = createBottomTabNavigator()

export default function () {
    return (
        <View style={{
            width,
            height,
        }}>
            <Tab.Navigator>
                <Tab.Screen
                    name="Screen1"
                    component={Component}
                />
                <Tab.Screen
                    name="Screen2"
                    component={Component}
                />
                <Tab.Screen
                    name="Screen3"
                    component={Component}
                />
            </Tab.Navigator>
        </View>
    )
}
