Even if you send 2 separate packets, the operating system will not be processed as 2 messages but only as a series of bytes. Therefore, there is no

How much value is appropriate and requires a combination of code.Pagedviewcelllayout Estimatecellhspan and Estimatecellvspan get the return value N (n is the column and row for the number of cells per screen).Take Estimatecellvspan as an example, int n = Math.max (1, (availheight + mheightgap)/(Mcellheight + mheightgap));Availheight is available height, availheight = Estimatecellvspan
