GridLayout列在较小的屏幕设备上消失

Question

我在ConstraintLayout中包含的GridLayout遇到了一些问题。在较大的屏幕设备（例如，Pixel 2/3 XL）上，GridLayout看起来很好，所有三列的内容均按预期显示。

在较小的屏幕设备上，只有第一列可见，而其他列似乎完全消失了。我在这里想念什么？

设计视图应该是这样

如果要测试较小的屏幕，请在活动或片段布局中添加scrollview和constraintlayout，然后添加包含。

只需制作layout width 0dp where you are using column weight并检查：
