Question

I need help with using an if statement in java, here is my code :

if(ans==1)
{

txtans.setText("This is a Prime Number");

}
else
{
txtans.setText("This is NOT a Prime Number");
}

if I remove the setText methods in both statements my program works, but when I leave them there and the program finds ans, then it quits, I’m wondering whats wrong with the statements? or is it not possible to use the setText method within if statements..if so how do I overcome this? What I want to do is print a string to the TextView layout when the ans = 1, any suggestions?

Answer 1

Yes, you can run txtans.setText() in an if statement just as well as you could run it if it wasn’t in an if statement. You likely just don’t have txtans initialised properly.

A quick google search brought up this as a way to print text to a textview.
