在Android中查看组边缘和视图边缘的距离

Question

如何在视图组边缘和视图边缘之间获取dp（s），如下图中标记的红色箭头？

这是我的布局文件

您可以将android:layout_weight="1"和android:gravity="right"添加到第一个（左侧）LinearLayout，并将android:layout_weight="1"和android:gravity="left"添加到第二个（右侧）LinearLayout以归档类似的结果。

<LinearLayout android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<LinearLayout
    android:id="@+id/ll_select_gander"

    android:orientation="horizontal">

    <LinearLayout
