看起来像这样
现在我想在RelativeLayout中使用相同的功能，但是我发现layout_weight在RelativeLayout中不起作用.我也不想在RelativeLayout中使用LinearLayout.
还是有任何其他方法可以像layout_weight在LinearLayout中一样工作，但对于RelativeLayout
Now i want the same in RelativeLayout, but i find layout_weight doesn't work in RelativeLayout. I also don't want to use LinearLayout inside RelativeLayout.
Or is there any alternative which can work same like layout_weight works in LinearLayout but for RelativeLayout
推荐答案
您不能使用百分比来定义RelativeLayout内View的尺寸.最好的方法是使用LinearLayout和权重或自定义布局.
You cannot use percentages to define the dimensions of a View inside a RelativeLayout. The best ways to do it is to use LinearLayout and weights, or a custom Layout.
