Let's take a look at the above method to calculate it: The system first assigns 3 TextView the width fill_parent they want, which means that each one fills his parent control, and here the width of the dead screen so this time the remaining space = 1 parent_width-3 parent_width=-2 a parent_width (parent_ Width refers to scr

Take the TextView and ImageView controls as an example, set to Wrap_
