Here you have an example I took from my own project, i have just removed what i thought we didnt need for the example.
import React, { Component } from 'react';
import {
Text,
TouchableOpacity,
View,
StyleSheet,
Dimensions,
Image
} from 'react-native';
class YourComponent extends Component {
constructor(props) {
super(props);
this._makeYourEffectHere = this._makeYourEffectHere.bind(this);
this.state = {
showPassword: false,
image: '../statics/showingPassImage.png'
}
}
render() {
return (
<View style={styles.container}>
<TouchableOpacity style={styles.button} onPress={this._makeYourEffectHere}>
<Text>button</Text>
<Image style={styles.image} source={require(this.state.image)}></Image>
</TouchableOpacity>
<TextInput password={this.state.showPassword} style={styles.input} value="abc" />
</View>
);
}
_makeYourEffectHere() {
var png = this.state.showPassword ? '../statics/showingPassImage.png' : '../statics/hidingPassImage.png';
this.setState({showPassword: !this.state.showPassword, image: png});
}
}
var styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: 'white',
justifyContent: 'center',
flexDirection: 'column',
alignItems: 'center',
},
button: {
width: Dimensions.get('window').width * 0.94,
height: 40,
backgroundColor: '#3b5998',
marginTop: Dimensions.get('window').width * 0.03,
justifyContent: 'center',
borderRadius: Dimensions.get('window').width * 0.012
},
image: {
width: 25,
height: 25,
position: 'absolute',
left: 7,
bottom: 7
},
input: {
width: Dimensions.get('window').width * 0.94,
height: 30
}
});
module.exports = YourComponent;
I hope It helps you.
Let me know if it was useful.
