Question

I divide a LinearLayout into say 7 different Views using weight_sum = 7 and the Views each have layout_weight = 1.
The whole LinearLayout spans over 100 pixels on the device.

100 pixels / 7 = 14.29 pixels.
Since pixels can only be integers the actual size in pixels of the 7 child views will be like this:

14 – 14 – 14 – 14 – 14 – 15 – 15

I’m now wondering which formula Android uses to calculate where to round down and where to round up.

For positioning, I would need to know it for any LinearLayout of size x with y child views.

Answer 1

From the source code, it casts the division to an int. See line 441.

Therefore, it always takes the floor integer value
