I am a beginner in xamarin android and I try to develop a simple app in xamarin android that makes decrement value into zero only ... but when I am trying the decrement value is continue to the negative value I cant makes it stop at zero value
how I can make decrement value stop at zero?
enter code here public class MainActivity : AppCompatActivity
{
int txt3;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.activity_main);
TextView textView1 = FindViewById<TextView>(Resource.Id.textView1);
txt3 = 5;
textView1.Click += delegate
{
textView1.Text = (txt3--).ToString();
};
}
}
}
when I run the app the value are 5 4 3 2 1 0 -1 -2 -3 ...etc

textView1.Click += delegate
{
result = text3--;
if (result < 0) {
result = 0;
}
textView1.Text = (result).ToString();
};

Here you are decrementing the value without checking whether it reached below 0 and that is why it is going to negative values. You can try
if(0 < txt3)
{
txt3 = txt3 - 1;
textView1.Text = Convert.ToString(txt3);
}
