如何在 react-native 中重叠

Question

您好，想在我的 react-native 应用中创建这样的 UI

但我是这样的

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>
                </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>

Answer 1

您必须使用 position:'absolute' 并将圆形元素作为元素列表的最后一个元素，使其位于顶部（无需使用 zIndex）。 容器 div 也必须具有使子元素居中的样式。不会有任何问题，因为您可以将该容器 div 放置在您想要的任何位置。

以下代码按预期工作。 （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）

<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>
