PercentRelativeLayout，如何以编程方式设置高度

您要设置一个新的百分比值吗？如果是，则需要：

View view = findViewById(R.id.view_child);PercentRelativeLayout.LayoutParams params = (PercentRelativeLayout.LayoutParams) view.getLayoutParams();// This will currently return null, if it was not constructed from XML.PercentLayoutHelper.PercentLayoutInfo info = params.getPercentLayoutInfo();info.heightPercent = 0.60f;view.requestLayout();
