android-ratiolayout's Issues

Square Layout

I know it's easy to create square layout - it's special case of RatioLayout with widthRatio=1 and heightRatio=1. However, could you please make square layout built-in in this library?

RatioLinearLayout

why there are no RatioLinearLayout?

反馈Android-RatioLayout问题

你好，当前我设置heightRatio和widthRatio比例后，然后我将手机切换成横屏模式，正确的情况应该是heightRatio和widthRatio的值调换一下顺序，这样才能够适配横屏，但是当我切换横屏模式后它们没有被调换，导致横屏使用的比例是竖屏的比例，导致横屏无法适配，这种情况应该怎么做呢？

RecyclerView GridLayoutManager

RatioFrameLayout is not rounding its corner from bottom

I have added RationFrameLayout but it is not rounding from bottom

        <net.soulwolf.widget.ratiolayout.widget.RatioFrameLayout
            android:layout_width="@dimen/_40sdp"
            android:layout_height="@dimen/_40sdp"
            android:visibility="gone"
            tools:visibility="visible"
            app:cardCornerRadius="4dp"
            app:cardElevation="4dp"
            app:datumRatio="datumAuto"
            app:layoutAspectRatio="1.0" />
