Question

我有一个看起来像这样的屏幕：

return (
    <SafeAreaView>
      <View style={styles.container}>
        <View style={styles.topContainer}>
          <View style={styles.searchFieldContainer}>
            <FavoritePointInput
              textChangeHandler={textChangeHandler}
            />
          </View>
          <View style={styles.dropdown}>
          <LocationsFound
            addressesFound={locations.favAddressesFoundList}
          />
          </View>
          <View style={styles.fieldDescription}>
            <Text>Set Location's Name:</Text>
          </View>
          <View style={styles.searchFieldContainer}>
            <Item style={styles.searchField}>
              <Input
                placeholder="Library"
                onChangeText={(text) => setLocationName(text)}
                style={styles.searchText}
              />
            </Item>
          </View> 
          <View style={styles.buttonContainer}>
            <Button style={styles.button}>
              <Text>Save Location</Text>
            </Button>
          </View>
          </View>
        </View>
    </SafeAreaView>
  );

其Stlyes如下：

export const styles = StyleSheet.create({
  container: {
    height: '100%',
    width: '100%',
  },
  topContainer: {
    height: moderateScale(750),
  },
  topTextContainer: {
    flexDirection: 'row',
    justifyContent: 'space-between',
    marginVertical: moderateScale(15),
    height: moderateScale(30),
    paddingLeft: moderateScale(30),
    paddingRight: moderateScale(30),
  },
  topMiddleContainer: {
    alignItems: 'center',
  },
  topMiddleText: {
    justifyContent: 'center',
    paddingBottom: 40,
  },
  searchFieldContainer: {
    alignItems: 'center',
    height: moderateScale(120),
  },
  button: {
    width: moderateScale(120),
    borderRadius: moderateScale(20),
    alignItems: 'center',
    alignContent: 'center',
  },
  buttonContainer: {
    flexDirection: 'row',
    justifyContent: 'center',
  },
  searchField: {
    width: moderateScale(300, 0.3),
    height: verticalScale(40),
    marginVertical: moderateScale(3),
    borderRadius: verticalScale(10),
  },
  fieldDescription: {
    alignItems: 'center',
  },
    dropdown:{
    position: 'absolute',
    top: 200,
  }
});

当我在第一个输入字段中输入内容时，我会通过LocationsFound组件获得搜索结果。但是，搜索结果开始隐藏在第二个输入字段的后面。我希望它简单地重叠并位于第二个字段的顶部，直到选择其中一个。有可能吗？

Answer 1

您尝试过zIndex吗？

dropdown:{
  position: 'absolute',
  top: 200,
  zIndex: 10,
  backgroundColor: '#fff'
}

您可以尝试做的第一件事是更改DOM对象的顺序，并确保将结果添加为最后一项：

return (
    <SafeAreaView>
      <View style={styles.container}>
        <View style={styles.topContainer}>
          <View style={styles.searchFieldContainer}>
            <FavoritePointInput
              textChangeHandler={textChangeHandler}
            />
          </View>
          <View style={styles.fieldDescription}>
            <Text>Set Location's Name:</Text>
          </View>
          <View style={styles.searchFieldContainer}>
            <Item style={styles.searchField}>
              <Input
                placeholder="Library"
                onChangeText={(text) => setLocationName(text)}
                style={styles.searchText}
              />
            </Item>
          </View> 
          <View style={styles.buttonContainer}>
            <Button style={styles.button}>
              <Text>Save Location</Text>
            </Button>
          </View>
          <View style={styles.dropdown}>
          <LocationsFound
            addressesFound={locations.favAddressesFoundList}
          />
          </View>
          </View>
        </View>
    </SafeAreaView>
  );

另一种解决方案是在您的dropDown中添加一个z-index：

    fieldDescription: {
        alignItems: 'center',
      },
        dropdown:{
        position: 'absolute',
        top: 200,
        zIndex: 1 // ... or more  
}

下拉菜单隐藏在内容后面
