在另一个布局上调用时，自定义视图layout_gravity不起作用

Question

我创建了一个自定义视图，当我在另一个布局上使用它时，ImageView上的layout_gravity无效。

继承人的代码

                android:layout_marginRight="@dimen/drawable_padding"
                android:layout_marginEnd="@dimen/drawable_padding" />
            <TextView

                android:layout_height="wrap_content"
                android:layout_weight="0.8"
                android:textColor="@color/warm_gray"
                android:textSize="@dimen/text_size_semi_large"
                android:text="Two line \n Text"/>
            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_vertical"
                android:layout_marginStart="@dimen/drawable_padding"
                android:layout_marginLeft="@dimen/drawable_padding"
                android:src="@drawable/ic_arrow_right_material"/>
