I have a problem with TouchableOpacity using negative margin so that different TouchableOpacities stay a little on top of each other (I’ll post an image to better understand). These buttons are being rendered into a FlatList and impressively on iOS works well, but on Android gets pretty strange.
On Android when I click on a button in front, is fired the back button.
Those are the buttons inside the FlatList, each button is on top of the other.
| iOS | Android |
|---|---|
![]() Click on the image to view it in its original size |
![]() Click on the image to view it in its original size |
On Android, when I clicked on the written button "Proposta 70", the written button "Proposta 78" was fired.
Android totally ignores the above items and always fires the item below, IE, the item that was rendered first
The code of FlatList
<View style={styles.containerList}>
<FlatList
data={proposalsList}
keyExtractor={item => item.proposta_id}
renderItem={({ item, index }) => (
<RenderItem
item={item}
index={index}
isLoweredCard={
openedCardIndex !== null && index === openedCardIndex + 1
}
changeOpenedCardIndex={changeOpenedCardIndex}
/>
)}
refreshing={loading}
onRefresh={() => getProposalsAndNotifications()}
/>
the button code (Renderitems)
<TouchableOpacity
style={styles.container(index, isLoweredCard)}
onPress={() => changeOpenedCardIndex(index)}
>
<>
<View
style={[
styles.lineContainer,
{ marginBottom: metrics.padding * 1.5 },
]}
>
<View
style={{
width: '50%',
}}
>
<Text style={styles.proposalId}>
{`Proposta ${item.proposta_id}`}
</Text>
<Text style={styles.proposalDate}>
{dayjs(item?.proposta_data_criacao).format('DD.MM.YYYY')}
</Text>
</View>
<View
style={{
flex: 1,
justifyContent: 'center',
alignItems: 'flex-end',
}}
>
<View style={styles.statusContainer}>
<Text style={{ fontSize: wp(4), fontWeight: 'bold' }}>
<TypeStatus status={item?.proposta_status} />
</Text>
</View>
</View>
</View>
<View style={styles.lineContainer}>
<Text style={styles.proposalDetailLabel}>Valor solicitado</Text>
<Text style={styles.proposalDetailValue}>
{formatCurrency(item?.proposta_valor_financiado)}
</Text>
</View>
<View style={styles.lineContainer}>
<Text style={styles.proposalDetailLabel}>Valor liberado</Text>
<Text style={styles.proposalDetailValue}>
{formatCurrency(item?.proposta_valor_financiado)}
</Text>
</View>
<View style={styles.lineContainer}>
<Text style={styles.proposalDetailLabel}>Parcelas</Text>
<Text style={styles.proposalDetailValue}>
{`${item?.proposta_valor_prazo}x`}
</Text>
</View>
<View style={styles.lineContainer}>
<Text style={styles.proposalDetailLabel}>Valor da parcela</Text>
<Text style={styles.proposalDetailValue}>
{formatCurrency(item?.proposta_valor_parcela)}
</Text>
</View>
<View style={styles.buttonContainer}>
<Button
onPress={goToDetails}
title="Ver detalhes"
titleStyle={styles.proposalButtonText}
style={styles.button}
/>
</View>
</>
</TouchableOpacity>
And the styles of the buttons
import {
widthPercentageToDP as wp,
heightPercentageToDP as hp,
} from 'react-native-responsive-screen';
import { metrics, colors } from '../../../../constants';
const styles = StyleSheet.create({
container: (index, isLoweredCard) => ({
backgroundColor: `#00${index}F${index}C`,
marginTop: !isLoweredCard && index !== 0 ? -wp(53) : metrics.padding,
marginHorizontal: metrics.padding,
alignContent: 'center',
padding: metrics.padding,
borderRadius: metrics.radius,
zIndex: -(index + 999),
}),
lineContainer: {
width: '100%',
justifyContent: 'space-between',
flexDirection: 'row',
marginBottom: metrics.padding / 2,
},
statusContainer: {
backgroundColor: colors.white,
borderRadius: 20,
width: '70%',
paddingVertical: 3,
alignItems: 'center',
justifyContent: 'center',
},
proposalId: {
color: colors.white,
fontWeight: 'bold',
fontSize: wp(4.5),
},
proposalDate: {
color: 'rgba(0, 0, 0, 0.5)',
fontWeight: 'bold',
fontSize: wp(3.5),
},
proposalDetailLabel: {
fontSize: wp(4),
color: 'rgba(0, 0, 0, 0.9)',
},
proposalDetailValue: {
fontSize: wp(4.5),
color: colors.white,
fontWeight: 'bold',
},
proposalButtonText: {
color: colors.white,
fontWeight: 'bold',
fontSize: wp(4),
},
button: {
borderRadius: metrics.radius,
backgroundColor: '#002F6C',
paddingHorizontal: metrics.padding * 3,
},
buttonContainer: {
width: '100%',
marginTop: metrics.padding,
alignItems: 'center',
},
});
export default styles;


Welcome to [en.so]! A tip, when you have a problem with RN, try to play it in a Snack , this will make it easier to decrease the problem to a [mcve] and will also make it easier for someone to help. I haven’t analyzed your entire code, but maybe the problem has to do with you changing the
z-indexfor iOS but not changing theelevationfor Android. Android does not make use ofz-index– Rafael Tavares
