I'm experiencing a NullpointerException with this code:
kuglebutton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if(toggle.isChecked())
{
counter1 = counter1 + 10;
column1tv.setText("" + counter1);
}
else
{
counter1 = counter1 - 2;
column1tv.setText("" + counter1);
}
}
});
Can anyone tell me what i'm doing wrong, and maybe how to fix it?
As blackbelt said, something is null. Use logcat to see exactly where you get the exception. When you found the place, the problem is sometimes obvious.
