GridLayout，android:layout_columnWeight，android:layout_rowWeight仅在API 21中使用，当前我的是16

所以我使用了一个网格布局，我有多个图像视图，这是我的完整视图

但仍然得到同样的错误，所以 我变了

android:layout_columnWeight

致：

但仍然没有得到想要的结果，因为在API小于21的情况下，设备没有考虑layout_columnWeight和layout_rowWeight这是否意味着我必须更改应用程序的minsdk？因为我真的不想也不想使用gridview

android:layout_columnWeight

app:layout_columnWeight
