The Android.App AlertDialog.Builder SetNegativeButton method creates a negative button for the alert dialog. This button is usually used for the cancel option, and can be customized by setting the button text and a listener that defines what happens when the button is clicked.

Example 1:

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.SetMessage("Are you sure you want to delete this item?")
    .SetCancelable(false)
    .SetNegativeButton("Cancel", (senderAlert, args) =>
                                {
                                    // Do something when negative button is clicked
                                })
    .SetPositiveButton("Yes", (senderAlert, args) =>
                                {
                                    // Do something when positive button is clicked
                                });
AlertDialog alertDialog = builder.Create();
alertDialog.Show();

In this example, an alert dialog is created with a message asking the user if they want to delete an item. The dialog is set to be not cancelable, and includes a negative button labeled "Cancel" and a positive button labeled "Yes". Clicking the negative button does nothing, but clicking the positive button triggers an action.

Package library for this example: Android.App.

Example 2:

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.SetTitle("Select your favorite color")
    .SetItems(colorsArray, (senderAlert, args) =>
                            {
                                string selectedColor = colorsArray[args.Which];
                                // Do something with the selected color
                            })
    .SetNegativeButton("Cancel", (senderAlert, args) =>
                                {
                                    // Do something when negative button is clicked
                                });
AlertDialog alertDialog = builder.Create();
alertDialog.Show();

This example creates an alert dialog that prompts the user to select their favorite color from a list. The dialog includes a "Cancel" button that does nothing, and a listener that retrieves the selected color and triggers an action. Package library for this example: Android.App.
