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

推荐答案

您必须使用 position:'absolute' 并将圆元素作为元素列表的最后一个元素，以便它位于顶部(无需使用 zIndex).此外，容器 div 必须具有使子元素居中的样式.不会有问题，因为您可以将容器 div 放置在您想要的任何位置.

You have have to use position:'absolute' and put the circle element as the last element of the elements list so it comes to top (no need to use zIndex). also the container div must have styles for child elements to be centered. There won't be an issue since you can position that container div where ever you want.

以下代码按您的预期工作.(我用视图"和不同的颜色替换了项目".你可以把这些东西改回来)

Following code works as you expected. (I replaced 'Item' with 'View' and different colors. You can change those things back)

<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>
