html - 查看个人资料图片

如屏幕截图所示，我想在“视图”上显示个人资料图像，该图像隐藏在视图后面。我正在使用React-native实现它。

顶部的红色视图，其中添加了个人资料图像。在其下添加带有阴影的另一个视图。


HTML代码

<Content style={styles.content}>
              <View style={styles.topView} transparent>
                <View style={styles.profileImageView}>
                  <Image
                    style={styles.profileImage}
                    source={require("../Images/avatar.png")}
                  />
                </View>
              </View>
              <View style={styles.middleView} transparent>
                <View />
                <View />
              </View>
   </Content>

CSS代码

content: {
    flex: 1,
    backgroundColor: "#f5f6f8"
  },
  topView: {
    marginTop: 30,
    marginLeft: 15,
    width: "100%",
    height: 40,
    backgroundColor: "red"
  },
  profileImageView: {
    width: 100,
    height: 100,
    marginLeft: 30,
    borderRadius: 5,
    backgroundColor: "yellow",
    position: "absolute"
  },
  profileImage: {
    width: "100%",
    height: "100%",
    position: "absolute"
    // marginLeft: 45,
    // marginTop: 30,
    // borderRadius: 5
  },
  middleView: {
    width: 360,
    height: 346,
    marginTop: 14,
    marginLeft: 15,
    borderRadius: 10,
    backgroundColor: "#ffffff",
    shadowColor: "#B8B8B8",
    shadowOffset: {
      width: 0,
      height: 10
    },
    shadowRadius: 20,
    shadowOpacity: 1
  }

我已经尝试过位置：“绝对”和覆盖：“隐藏”。但是，对我没有任何作用。

希望有更好的解决方案。

最佳答案

请使用z-index属性来实现上述结构。
注意：我已包含引导程序以具有导航栏结构。您可能会完全淘汰它，并在代码中使用提到的CSS。

img {
  margin-bottom: -120px;
  z-index: 1;
  position: relative;
}

.text {
  border: solid 1px red;
  min-height: 200px;
  z-index: 2;
  background-color: pink;
  position: relative;
  width: 100%;
  margin-top: 20px;
}
