线性和相对布局之间的区别是什么?
What is the difference between linear and relative layout?
线性布局,把每一个孩子,一前一后,在一条线上,水平或垂直。有了一个相对布局,你可以给每个孩子一个LayoutParam指定的确切位置是应该去,相对于父母或相对于其他的孩子。
Linear layouts put every child, one after the other, in a line, either horizontally or vertically. With a relative layout you can give each child a LayoutParam that specifies exactly where is should go, relative to the parent or relative to other children.
