javascript - unable to scroll in scrollView

I have a screen where I type in the input field and get search results accordingly. The list is rendered within a ScrollView but it still doesn't let me scroll when the keypad is open (in Android ).

How can I fix this?

  return (
    <>
      {addressesFound.length > 0 ? (
        <ScrollView
          style={styles.searchResultsContainer}
          keyboardShouldPersistTaps={'always'}
          keyboardDismissMode={'on-drag'}>
          {addressesFound.map((addressDetails: addressDetailsType) => {
            return (
              <View
                key={addressDetails.placeName}
                style={styles.resultContainer}>
                <Text
                  style={styles.text}>
                  {addressDetails.placeName}
                </Text>
              </View>
            );
          })}
        </ScrollView>
      ) : null}
    </>
  );
};
const styles = StyleSheet.create({
  searchResultsContainer: {
    width: moderateScale(400),
    paddingHorizontal: moderateScale(50),
    paddingRight: moderateScale(65),
    marginTop: moderateScale(10),
   flex:1,
  },
  resultContainer: {
    marginTop: moderateScale(10),
    borderBottomWidth: 1,
    borderBottomColor: 'grey',
  },
  text: {
    fontSize: moderateScale(15),
  },
});

enter image description here

I have already tried adding nestedScrollEnabled={true} but it makes no difference.

This is where the above mentioned component is called:

        <View style={styles.dropdown}>
          <LocationsFound
            addressesFound={locations.addressesFoundList} />
....
  dropdown: {
    position: 'absolute',
    top: moderateScale(215),
    zIndex: moderateScale(10),
    backgroundColor: '#fff',
    flex: 1,
  },

I tried adding height: 80% to dropdown. This makes it possible to scroll a bit. However, when the keypad is open I can scroll but not to the end. If I add height: 100%, I am not able to scroll at all.

I think that if your ScrollView contents are smaller than the screen, it won't scroll. So you can try making height: "150%" or something like that or add in an empty view with a height to stretch your ScrollView higher than your screen.

Wrapping ScrollView in a View with height > the screen will work too.
