A question about Layout_weight:

The current screen size is 430. There are two controls. Before the unassigned weight is set to 300, the weight of the left control is 3, and the weight of the right control is 2, calculate the width of the two controls?

Solution:

The total number of remaining controls on the current screen is: 400-300-300 =-170, and-170 is allocated to two controls.

The width of the left control after weight distribution is: 300 + (-170) * 3/5 = 198

The width of the left control after weight distribution is: 300 + (-170) * 2/5 = 232
