I need that in the textview displays in order 1, 2, 3, 4 etc. But the value it receives from dados.getdia() is always 3, 5, 7, 9, 11 etc. I have tried several things.

In this code below it works up to when it gets 5, then when it gets 7, it displays 5 instead of 4, which would be correct. How can I do this?

int dia = dados.getDia();
if(dia == 3){
    Log.d(TAG,"entrou Dia ==3");
    int dia2 = dia-1 ;
    txv_dia.setText(String.valueOf(dia2));
}else if(dia >3){
    Log.d(TAG,"entrou Dia >3");
    int dia2 = dia-3 ;
    txv_dia.setText(String.valueOf(dia2));
}

  • It seems easy to solve your problem, but I barely understood what you tried to explain. Could you elaborate a little more? Do you want to show only odd days? or only pairs?

  • I want to display 1,2,3 however I get odd, but it seems that I managed to solve here, I made a counter and subtract the day - counted, I’m doing the tests here

As I believe you want to print the position of the prime numbers, you cannot have the == 3, >3 and -3, because the difference between the numbers always increases.

You’ll have to treat them considering the difference between them to find the position.
