Cardview不在RelativeLayout的后面位置

Question

我在RelativeLayout中实现CardView有问题。我将CardView设置在RelativeLayout的后面位置。但这似乎不是我想要的。

我想这样（由photosop编辑）：

当前显示（在实时设备和Android工作室上）

这是xml：

for x in range(0, len(my_hexplode_chains) - 1):
    match_found = False
    for y in range(x + 1, len(my_hexplode_chains)):
        for tile_id_x, tile_x in my_hexplode_chains[x].items():             #compare each chain in list
            for tile_id_y, tile_y in my_hexplode_chains[y].items():         #to every other chain
                for neighbour in tile_x["neighbours"]:                      #if tiles in different lists
                    if neighbour == tile_id_y:                              #are neighbours
                        match_found = True
                        my_hexplode_chains[x].update(my_hexplode_chains[y]) #append one chain to the other
                        del my_hexplode_chains[y]                           #delete appended chain
                if match_found:                                             #continue loop at next chain
                    break                                                   #very ugly way to do this
            if match_found:
                break
        if match_found:
            break
    if match_found:
        break

我也实现了<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"

</RelativeLayout> ，但它不起作用，所以如何修复它？ sory for my English

我将PercentRelativeLayout放在CardView内并且有效。

希望这会有所帮助：）
