拉伸高度以适应原生的反应内容

Question

我想改变模态的高度以适应内容.它总是只是到屏幕的高度:

JSX:

  <Modal style={styles.modal}
    isVisible={props.categories.some(x => showModal(x))}>
    <Container style={styles.modalView}>
      <Header style={styles.header}>
        <Left>
          <Title 
            style={styles.title}>{getDisplayedCategoryLabel(props.categories)}
          </Title>
        </Left>
        <Right>
          <Button 
            small 
            transparent 
            danger 
            rounded 
            icon 
            onPress={() => props.setAllShowSubcategoriesToFalse()}>
            <Icon name="times" size={20} color='#9E9E9E' />
          </Button>
        </Right>
      </Header>
      <Content >
        <SelectMultiple
          labelStyle={styles.label}
          items={getDisplaySubcategories(props.categories)}
          selectedItems={
            props.categories.filter(category => category.selected)
          }
          onSelectionsChange={props.toggleSubcategory} />
      </Content>
    </Container>
  </Modal>

款式:

    const styles = {
  modalView: {
    flex: 1,
    backgroundColor: '#FFFFFF',
    padding: 20,
    borderRadius: 8,
    height: 100
  },
  modal: {
    padding: 10,
    height: 100
  }
    }

更改modal样式的高度不起作用.我似乎无法改变高度.我应该怎么做才能影响身高？

我正在使用react-native-modal

怎么样：

 <Modal transparent>
   <View style={{ flex: 1, alignItems: 'center', backgroundColor: 'rgba(0,0,0,0.5)' }}>

     {/* fill space at the top */}
     <View style={{ flex: 1, justifyContent: 'flex-start' }} />


     <View style={{ flex: 1, backgroundColor: 'white' }}>
       {/* content goes here */}
     </View>

     {/* fill space at the bottom*/}
     <View style={{ flex: 1, justifyContent: 'flex-end' }} />
   </View>
 </Modal>
