how i makes decrement value stop at zero












0















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

            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);
            }
