Android GridLayout,每行有动态列数

我有不同宽度的卡片,我想创建一个网格布局,其中width =匹配父级(填充屏幕)和固定高度.
我想在网格布局中设置卡片,因此列数会相应地改变为可以适合该行的元素的宽度.

因此,元素将被设置为水平行,直到它们适合屏幕,然后转到下一行,当它们超过固定高度时,使用垂直滚动.

我正在尝试使用网格布局,但我不知道它是否适合这种解决方案.
我使用原生Android.

这里的图片应如下所示：

谢谢.

解决方法:

你可以使用FlexboxLayoutManager

将以下依赖项添加到build.gradle文件中：

implementation 'com.google.android:flexBox:0.3.2'

示例代码

LAYOUT.XML

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <android.support.v7.widget.RecyclerView
      android:id="@+id/recyclerView"
      android:layout_width="match_parent"
      android:layout_height="250dp" />



</LinearLayout>
