How to Insert a Override Function into a If Else Statement

Different Override method based on condition

You can create different implementations of an interface which shares the dispatchTouchEvent method. Take a look at the Strategy Pattern.

Multiple IF functions in Excel: how to override on IF statement if another IF is true.

You need to use the AND(logical1, [logical2], ...) function of Excel in your IF statements to concatenate more conditions. (read more about AND here: https://support.office.com/en-us/article/AND-function-5f19b2e8-e1df-4408-897a-ce285a19e9d9)

Also you need to turn the logic around. You need to check if all fields are TRUE first. Then if field 2-8 are TRUE and so on...

So your statement would look something like this:

IF(AND(A8=TRUE,A7=TURE, A6=TRUE, ...), 1,
    IF(AND(A8=TRUE,A7=TURE, ...), 2,
        IF(AND(A8=TRUE, ...), 3,)
    )
)

How to override a method only if a condition is found to be true?

You can't make a runtime decision about whether a method is overridden (without generating classes dynamically, which is complicated [and I have no idea if it's supported in Dalvik]).

Just check your condition in the method:

protected void attachBaseContext(Context base) {
    if (this.value) {
        // Your special behavior
        super.attachBaseContext(ZeTarget.attachBaseContext(base,this));
    } else {
        // The super's behavior, as though you hadn't overridden the method
        super.attachBaseContext(base);
    }
}

Method Override with some condition in Console application

In ChildClass you can do something like this:

public partial class ChildClass : MainCLass
{
    public override void Method1()
    {
        if(condition)
        {
            base.Method1();

            return;
        }

        //YOUR LOGIC
    }
}

EXAMPLE

public class A
    {
        public virtual void MethodA()
        {
            Console.WriteLine("A:MethodA");
        }
    }

    public class B : A
    {
        public bool CallBase { get; set; }

        public B()
        {
            CallBase = false;
        }

        public override void MethodA()
        {
            if (CallBase)
            {
                base.MethodA();

                return;;
            }

            Console.WriteLine("B:MethodA");
        }
    }

    class Program
{
    static void Main(string[] args)
    {
        A a = new A();
        B b = new B();

        a.MethodA();
        b.MethodA();

        b.CallBase = true;

        b.MethodA();

        A c = new B();

        c.MethodA();

        A d = new B(true);

        d.MethodA();

        Console.ReadKey();
    }
}

Output

A:MethodA
B:MethodA
A:MethodA
B:MethodA
A:MethodA
