I am creating a small app that has a to-do list and a calendar. At the bottom is a bottom tab navigator. Everything works and is functional, however, when I try to add style: {} inside tabBarOptions it isn’t being applied. Changing activeTintColor, inactiveTintColor and labelStyle works just fine.
I tried to create a stylesheet and replace everything inside tabBarOptions, but that didn’t work. My main goal is to simply create a slightly larger bar along the bottom of the screen. I don’t even want a crazy custom navigation bar, just slightly larger so I can make the items inside a little bigger.
MainContainer Class:
import React from 'react';
import {StyleSheet} from 'react-native';
import {NavigationContainer} from '@react-navigation/native';
import {createBottomTabNavigator} from '@react-navigation/bottom-tabs';
import Ionicons from 'react-native-vector-icons/Ionicons'
//screens
import Calendar from './screens/Calendar';
import ToDoList from './screens/ToDoList';
// Screen names
const calendarName = 'Calendar';
const ToDoListName = 'To Do List';
const Tab = createBottomTabNavigator();
export default function MainContainer() {
return (
<NavigationContainer>
<Tab.Navigator
tabBarOptions={{
activeTintColor: 'tomato',
inactiveTintColor: 'black',
labelStyle: {paddingBottom: 10, fontSize: 10},
style: {padding: 10, height: 70},
}}
initialRouteName={ToDoListName}
screenOptions={({route}) => ({
tabBarIcon: ({focused, color, size}) => {
let iconName;
let rn = route.name;
if (rn === ToDoListName) {
iconName = focused ? 'list' : 'list-outline'; //icons in package. Change later.
} else if (rn === calendarName) {
iconName = focused ? 'calendar' : 'calendar-outline'
}
return <Ionicons name={iconName} size={size} color={color}/>
},
})}>
<Tab.Screen name={ToDoListName} component={ToDoList}/>
<Tab.Screen name={calendarName} component={Calendar}/>
</Tab.Navigator>
</NavigationContainer>
)
}
For reference here is my ToDoList class
import { KeyboardAvoidingView, StyleSheet, Text, View, TextInput, TouchableOpacity, Platform, Keyboard } from 'react-native';
import Task from '../../components/Task';
import React, { useState } from 'react';
import { ScrollView } from 'react-native-web';
export default function ToDoList() {
const [task, setTask] = useState();
const [taskItems, setTaskItems] = useState([]);
const handleAddTask = () => {
Keyboard.dismiss();
setTaskItems([...taskItems, task])
setTask(null);
}
const completeTask = (index) => {
let itemsCopy = [...taskItems];
itemsCopy.splice(index, 1);
setTaskItems(itemsCopy)
}
return (
<View style={styles.container}>
{/* Scroll View when list gets longer than page */}
<ScrollView contentContainerStyle={{
flexGrow: 1
}} keyboardShouldPersistTaps='handled'>
{/*Today's Tasks */}
<View style={styles.tasksWrapper}>
<Text style={styles.sectionTitle}>Today's Tasks</Text>
<View style={styles.items}>
{/* This is where the tasks will go*/}
{
taskItems.map((item, index) => {
return (
<TouchableOpacity key={index} onPress={() => completeTask(index)}>
<Task text={item} />
</TouchableOpacity>
)
})
}
</View>
</View>
</ScrollView>
{/* Write a task section */}
{/* Uses a keyboard avoiding view which ensures the keyboard does not cover the items on screen */}
<KeyboardAvoidingView
behavior={Platform.OS === "ios" ? "padding" : "height"}
style={styles.writeTaskWrapper}>
<TextInput style={styles.input} placeholder={'Write a task'} value={task} onChangeText={text => setTask(text)} />
<TouchableOpacity onPress={() => handleAddTask()}>
<View style={styles.addWrapper}>
<Text style={styles.addText}>+</Text>
</View>
</TouchableOpacity>
</KeyboardAvoidingView>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#E8EAED',
},
tasksWrapper: {
paddingTop: 20,
paddingHorizontal: 20,
},
sectionTitle: {
fontSize: 24,
fontWeight: 'bold',
},
items: {
marginTop: 30,
},
writeTaskWrapper: {
position: 'absolute',
bottom: 20,
paddingLeft: 10,
paddingRight: 10,
width: '100%',
flexDirection: 'row',
justifyContent: 'space-between',
alignItems: 'center'
},
input: {
paddingVertical: 15,
width: 250,
paddingHorizontal: 15,
backgroundColor: '#FFF',
borderRadius: 60,
borderColor: '#C0C0C0',
borderWidth: 1,
},
addWrapper: {
width: 60,
height: 60,
backgroundColor: '#FFF',
borderRadius: 60,
justifyContent: 'center',
alignItems: 'center',
borderColor: '#C0C0C0',
borderWidth: 1,
},
addText: {
},
});
And my Calendar class
import * as React from 'react';
import { View, Text } from 'react-native';
export default function Calendar(){
return(
<View>
<Text>Calendar Will go here</Text>
</View>
)
}
I made a Task component for the ToDoList. Not sure if you need it to solve this but I’ll paste it here anyway.
import React from 'react';
import { View, Text, StyleSheet } from 'react-native';
import { TouchableOpacity } from 'react-native-web';
const Task = (props) => {
return (
<View style={styles.item}>
<View style={styles.itemLeft}>
<View style={styles.square}></View>
<Text style={styles.itemText}>{props.text}</Text>
</View>
<View style={styles.circular}></View>
</View>
)
}
const styles = StyleSheet.create({
item: {
backgroundColor: '#FFF',
padding: 15,
borderRadius: 10,
flexDirection: 'row',
alignItems: 'center',
justifyContent: 'space-between',
marginBottom: 20,
},
itemLeft: {
flexDirection: 'row',
alignItems: 'center',
flexWrap: 'wrap',
},
square: {
width: 24,
height: 24,
backgroundColor: '#55BCF6',
opacity: .4,
borderRadius: 5,
marginRight: 15,
},
itemText: {
maxWidth: '80%',
},
circular: {
width: 12,
height: 12,
borderColor: '#55BCF6',
borderWidth: 2,
borderRadius: 5
},
});
export default Task;
