Android广告图保持不变形宽高比设置

根据设计的宽高比，如需宽度占满手机屏幕，或是默认宽度时，根据原图片的宽高比来设置高度，是图片不变形展示：

private static void adapterHeight(final View view, final float radioWH) {
    view.post(() -> {
        int width  = (view.getContext().getResources().getDisplayMetrics().widthPixels);
        ViewGroup.LayoutParams params = view.getLayoutParams();
        params.height = (int) (width * radioWH);
        view.setLayoutParams(params);
    });
}
