这是我的代码

<View style={{flex: 1,flexDirection:'row'}}>
            <View style={{flexDirection:'column',justifyContent:'center',alignItems:'center',alignSelf:'center'}}>
                <View style={{flex: 1,flexDirection:'row',alignItems:'flex-end',alignSelf:'flex-end',margin:10}}>
                    <Item style={{backgroundColor:AppColors.white,borderRadius:10,flexDirection:'column',height:100, width:100}}></Item>
                </View>
                <View style={{flex: 1,flexDirection:'row',alignItems:'flex-start',alignSelf:'flex-end',margin:10}}>
                    <Item style={{backgroundColor:AppColors.white,borderRadius:10,flexDirection:'column',height:100, width:100}}></Item>
                </View>
            </View>
            <View style={{justifyContent:'center',alignItems:'center',alignSelf:'center'}}>
                <Item style={{backgroundColor:AppColors.colorPrimaryDark,
                    borderRadius:10,height:100, width:100, borderRadius:100/2}}></Item>
            </View>
            <View style={{flexDirection:'column',justifyContent:'center',alignItems:'center',alignSelf:'center'}}>
                <View style={{flex: 1,flexDirection:'row',alignItems:'flex-end',alignSelf:'flex-start',margin:10}}>
                    <Item style={{backgroundColor:AppColors.white,borderRadius:10,flexDirection:'column',height:100, width:100}}></Item>

你必须使用位置:&#39;绝对&#39;并将circle元素作为元素列表的最后一个元素,使其显示在顶部(无需使用zIndex)。 容器div也必须具有子元素居中的样式。由于您可以将容器div定位在任何您想要的位置,因此不会成为问题。

以下代码按预期工作。 (我用&#39; View&#39;以及不同颜色替换了&#39;项目&#39;你可以改变这些东西)

<View style={{flex: 1,flexDirection:'row', backgroundColor:'green', justifyContent:'center', alignItems:'center'}}>
                <View style={{flexDirection:'column',justifyContent:'center',alignItems:'center',alignSelf:'center'}}>
                    <View style={{flex: 1,flexDirection:'row',alignItems:'flex-end',alignSelf:'flex-end',margin:10}}>
                        <View style={{backgroundColor:'white',borderRadius:10,flexDirection:'column',height:100, width:100}}></View>
                    </View>
                    <View style={{flex: 1,flexDirection:'row',alignItems:'flex-start',alignSelf:'flex-end',margin:10}}>
                        <View style={{backgroundColor:'white',borderRadius:10,flexDirection:'column',height:100, width:100}}></View>
                    </View>
                </View>

                <View style={{flexDirection:'column',justifyContent:'center',alignItems:'center',alignSelf:'center'}}>
                    <View style={{flex: 1,flexDirection:'row',alignItems:'flex-end',alignSelf:'flex-start',margin:10}}>
                        <View style={{backgroundColor:'white',borderRadius:10,flexDirection:'column',height:100, width:100}}></View>
                    </View>
                    <View style={{flex: 1,flexDirection:'row',alignItems:'flex-start',alignSelf:'flex-start',margin:10}}>
                        <View style={{backgroundColor:'white',borderRadius:10,flexDirection:'column',height:100, width:100}}></View>
                    </View>
                </View>

                <View style={{justifyContent:'center',alignItems:'center',alignSelf:'center', position:'absolute'}}>
                    <View style={{backgroundColor:'blue',
                        borderRadius:10,height:100, width:100, borderRadius:100/2}}></View>
       </View>
</View>
