React Native fixed footer

Question

I try to create react native app that looks like existing web app. I have a fixed footer at bottom of window. Do anyone have idea how this can be achieved with react native?

Answer 1

When flex is a positive number, it makes the component flexible and it will be sized proportional to its flex value. So a component with flex set to 2 will take twice the space as a component with flex set to 1.

   <View style={{flex: 1}>
            
     <ScrollView>
        //your scroll able content will be placed above your fixed footer content. 
        //when your content will grow bigger and bigger it will hide behind 
        //footer content. 
     </ScrollView>

     <View style={styles.footerContainer}>
        //your fixed footer content will sit fixed below your screen 
     </View>

</View>

The way I did this was to have a view (lets call it P) with flex 1, then inside that view have 2 more views (C1 and C2) with flex 0.9 and 0.1 respectively (you can change the flex heights to required values). Then, inside the C1 have a scrollview. This worked perfectly for me. Example below.

<View style={{flex: 1}}>
    <View style={{flex: 0.9}}>
        <ScrollView>
            <Text style={{marginBottom: 500}}>scrollable section</Text>
        </ScrollView>
    </View>
    <View style={{flex: 0.1}}>
        <Text>fixed footer</Text>
    </View>
</View>

I found using flex to be the simplest solution.

<View style={{flex:1, 
    justifyContent: 'space-around', 
    alignItems: 'center',
    flexDirection: 'row',}}>

  <View style={{flex:8}}>
    //Main Activity
  </View>
  <View style={{flex:1}}>
    //Footer
  </View>

 </View>

Here's the actual code based on Colin's Ramsay answer:

<View style={{flex: 1}}>
  <ScrollView>main</ScrollView>
  <View><Text>footer</Text></View>
</View>

@Alexander Thanks for solution

Below is code exactly what you looking for

import React, {PropTypes,} from 'react';
import {View, Text, StyleSheet,TouchableHighlight,ScrollView,Image, Component, AppRegistry} from "react-native";

class mainview extends React.Component {
 constructor(props) {
      super(props);

  }

  render() {
    return(
      <View style={styles.mainviewStyle}>
        <ContainerView/>
          <View style={styles.footer}>
          <TouchableHighlight style={styles.bottomButtons}>
              <Text style={styles.footerText}>A</Text>
          </TouchableHighlight>
          <TouchableHighlight style={styles.bottomButtons}>
              <Text style={styles.footerText}>B</Text>
          </TouchableHighlight>
          </View>
      </View>
    );
  }
}

class ContainerView extends React.Component {
constructor(props) {
      super(props);
}

render() {
    return(
      <ScrollView style = {styles.scrollViewStyle}>
          <View>
            <Text style={styles.textStyle}> Example for ScrollView and Fixed Footer</Text>
          </View>
      </ScrollView>
    );
  }
}

var styles = StyleSheet.create({
  mainviewStyle: {
  flex: 1,
  flexDirection: 'column',
},
footer: {
  position: 'absolute',
  flex:0.1,
  left: 0,
  right: 0,
  bottom: -10,
  backgroundColor:'green',
  flexDirection:'row',
  height:80,
  alignItems:'center',
},
bottomButtons: {
  alignItems:'center',
  justifyContent: 'center',
  flex:1,
},
footerText: {
  color:'white',
  fontWeight:'bold',
  alignItems:'center',
  fontSize:18,
},
textStyle: {
  alignSelf: 'center',
  color: 'orange'
},
scrollViewStyle: {
  borderWidth: 2,
  borderColor: 'blue'
}
});

AppRegistry.registerComponent('TRYAPP', () => mainview) //Entry Point    and Root Component of The App

Below is the Screenshot

Simple stuff here:

Incase you don't need a ScrollView for this approach you can go with the below code to achieve Something like this :

<View style={{flex: 1, backgroundColor:'grey'}}>
    <View style={{flex: 1, backgroundColor: 'red'}} />
    <View style={{height: 100, backgroundColor: 'green'}} />
</View>
