Contents in this project Remove Text Input Bottom Underline :
1. Start a fresh React Native project. If you don’t know how then read my this tutorial.
2. Add AppRegistry, StyleSheet, TextInput and View component in import block.
|
1 |
import { AppRegistry, StyleSheet, TextInput, View } from 'react-native'; |
3. Add View as parent view in render’s return block.
|
1 2 3 4 5 6 7 8 9 10 11 |
render() { return ( <View> </View> ); } |
4. Create custom css class named as MainContainer just above the AppRegistry.registerComponent line.
|
1 2 3 4 5 6 7 8 9 10 11 12 |
const styles = StyleSheet.create({ MainContainer :{ // Setting up View inside content in Vertically center. justifyContent: 'center', flex:1, margin: 10 } }); |
5. Call the MainContainer class in View.
|
1 2 3 4 5 6 7 8 9 10 |
render() { return ( <View style={styles.MainContainer}> </View> ); } |
6. Create another class named as TextInputStyleClass . Using the TextInputStyleClass we have been setting up Text Input hint align center and height as 50 pixels.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
const styles = StyleSheet.create({ MainContainer :{ // Setting up View inside content in Vertically center. justifyContent: 'center', flex:1, margin: 10 }, TextInputStyleClass:{ // Setting up Hint Align center. textAlign: 'center', // Setting up TextInput height as 50 pixel. height: 50 } }); |

<View style={styles.MainContainer}> <TextInput // Adding hint in Text Input using Place holder. placeholder="Enter Text in TextInput" // Making the Under line Transparent. underlineColorAndroid='transparent' // Calling the custom TextInputStyleClass. style={styles.TextInputStyleClass}/> </View> |
