3. Assuming that the screen width is 480p, then when three textview widths are not match_parent. Assign the size of the control declaration first, and then assign the remaining press weight. (The result can be negative)

4. When there is only one textview, we want it to occupy half the screen width, you can set weightsum= "2", such as
