ReactNative:Styles 相互覆盖，容器错位

Question

  render() {
    if (this.state.isLoading) {
      return (
        <View style={styles.container}>
          <ActivityIndicator />
        </View>

    } else {
      let launches = this.state.dataSource.map((item, key) => {
        return (
          <View key={key} style={styles.container}>
            <Image
              style={{ width: 350, height: 520, borderRadius: 10 }}
              source={{ uri: item.rocket.imageURL }}

            <Entypo
              name="map"
              color={"white"}
              size={24}
              style={styles.MapIcon}
              onPress={() => Linking.openURL(item.location.pads[0].mapURL)}
            />
            <Entypo

            />

            <View style={styles.subcontainer}>

        );
      });

      return (
        <View style={styles.Background}>
          <ScrollView contentContainerStyle={styles.contentContainer}>
            {launches}

    }
  }
}

const styles = StyleSheet.create({
  Background: {
    backgroundColor: "#e8e8e8"
  },
  contentContainer: {
    padding: 3,
    backgroundColor: "#e8e8e8"

  subcontainer: {
    backgroundColor: "rgb(249, 249, 249)",
    position: "absolute",
    borderRadius: 2,
    padding: 10,
    marginTop: 420,
    width: "100.65%",
    marginLeft: "2.94%",
    shadowColor: "grey",
    shadowOpacity: 0.5,
    shadowRadius: 2,
    shadowOffset: { width: 0, height: -1 }
  },
  container: {
    flex: 1,
    borderRadius: 10,
    backgroundColor: "rgba(249, 249, 249, 0.8)",
    padding: 10,
    borderWidth: 0.5,
    borderColor: "#CCCCCC",
    marginTop: 4
  },
  Title: {
    color: "#007AFF",
    fontSize: 18,
    textAlign: "center",
    lineHeight: 18,
    paddingBottom: 5,
    fontWeight: "bold"
  },
  Text: {
    color: "black",
    fontSize: 14,
    textAlign: "left"

    marginLeft: "8%"
  },
  VideoIcon: {
    position: "absolute",
    marginTop: "7%",
    marginLeft: "92%"
  }
});

下面的图片显示了更好的表示，但为了彻底解释它，我有一个容器，里面有一个子容器，其中包含有关发射名称、位置、日期、火箭等的信息，以及子容器-container 应该很好地适合每个 container/card （卡片用于每个火箭发射事件，它有自己的带有填充等的容器）但有时一些文本变得太长而不得不占用另一行。这迫使子容器向下移动（显示在“它不应该如何”图像中并从 container/card 延伸出去。Q: 有没有办法让每当文本需要另一行时，子容器会随着其中的文本向上移动，因此它仍然适合 container/card 并且不会延伸到它之外？或其他解决方案。

One way to solve this problem is to absolute position your subContainer to the bottom of the Container using bottom:0, instead of providing marginTop:420. This way the subContainer View will always stick to the bottom of the Container View. Whereas providing marginTop:420 will make the subContainer View always have marginTop of 420 which will push it down when it becomes big. You can also play with left: 0 and right: 0 for the subContainer to occupy the full width of its parent View, i.e the Container.

class App extends React.Component {
  render() {
    return (
      <ScrollView style={{marginTop: 25}} >
        {[1,2,3,4,5].map(() => (
          <View style={styles.container}>
            <View style={styles.subContainer} >
              <Text>on every element in the calling array on every element in the calling array on every element in the calling array</Text>
            </View>
          </View>
        ))}
      </ScrollView>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    backgroundColor: 'blue',
    height: 300,
    margin: 10
  },
  subContainer: {
    backgroundColor: '#eee',
    position: 'absolute',
    bottom: 0,
    right: 0,
    left: 0,
    margin: 10,
    padding: 5,
    borderRadius: 2
  },
});
