I am using TouchableHighlight, but I can change only background color using underlayColor. But how to change other content?
With TouchableHighlight you can do it like this
state = { selected: false };
setSelected(selected: boolean) {
this.setState({ selected: selected });
}
textStyle() {
return this.state.selected ? styles.textSelected : styles.text;
}
And then in the render function
<TouchableHighlight
underlayColor={Theme.palette.accent}
onPress={() => onPress()}
onShowUnderlay={() => this.setSelected(true)}
onHideUnderlay={() => this.setSelected(false)}
>
<Text style={this.textStyle()}>{text}</Text>
</TouchableHighlight>
This answer is assuming you want to change the color just while the button is depressed:
Use TouchableWithoutFeedback and define your own onPressIn and onPressOut functions to change the text color.
<TouchableWithoutFeedback onPressIn={this.colorText} onPressOut={this.resetText}>
<Text style={[styles.textColored()]}>MyText</Text>
</TouchableWithoutFeedback>
colorText: function() {
this.setState({textColored: true});
},
resetText: function() {
this.setState({textColored: false});
},
textColored: function() {
if(this.state.textColored) {
return styles.textColored;
} else {
return styles.textNormal;
}
}
