javascript - React Native Scroll View 不滚动也不跳到底部

Question

我是 React Native 的新手，我对 .滚动不适用于 ScrollView。

我尝试将“flex:1”赋值给 ，也尝试将它包裹起来，但没有用...

我已经尝试了多种提供“flex:1”来查看和 ScrollView 的解决方案，但似乎没有任何效果......

谁能帮我解决这个问题？此外，如果您能告诉我如何在向 scrollView 添加新内容时反弹/跳转到 scrollView 的底部，那将非常棒。

谢谢。

下面是我的代码:

<Container>
<Content style={{backgroundColor: 'white'}}>                  
    <ScrollView contentContainerStyle={{ flex: 1 }}>
      <View style={{flex: 1, flexDirection: 'column', alignItems: 'center', marginTop: 20, height: 555, }}>
        <View 
          style={{
            width: 80, 
            height: 80, 
            backgroundColor:'#959595',
            borderRadius: 50,
          }}
        />
        <Text style={{fontWeight: 'bold', marginTop: 15}}>Personal Assistant</Text>

        <View style={{flexDirection: 'row', marginTop: 25, marginLeft: 15}}>
          <View 
            style={{
              width: 50, 
              height: 50, 
              backgroundColor:'#E3E3E3',
              borderRadius: 50,
            }}
          />

          <View style={{flex: 1, flexDirection: 'column', marginLeft: 15, marginRight: 15}}>
            <View style={{backgroundColor: "#E3E3E3", borderRadius: 10, padding: 10}}>
              <Text>

您有没有使用过 Native Base？如果是，他们的 Content 组件实际上是一个 ScrollView。所以在你的情况下，你有 2x ScrollViews。我会删除 <ScrollView contentContainerStyle={{ flex: 1 }}> ，并且只有 <Container><Content><View style....
