Question

So I have searched through a few question here regarding the AlertDialog, and I’m not completely sure what I’m doing, so I am having a hard time relating those questions to my own example. (I’m still new to this whole android programming so please bear with me.)

I have defined this under the public class _ Activity implements OnCLickListener …

    public AlertDialog myAlertDialog;

And then I have this under the onClick

    public void onClick(View src) {

    switch(src.getId()){
    case R.id.buttonOk:
        if (score==0){
            AlertDialog.Builder myAlertDialog = new AlertDialog.Builder(this);
            myAlertDialog.setTitle("Title");
            myAlertDialog.setMessage("Message");
            myAlertDialog.setButton("OK", new DialogInterface.OnClickListener() {
                  public void onClick(DialogInterface dialog, int which) {
                    return;
                } }); 
            myAlertDialog.show();
        }

This line and the line below it have errors:

myAlertDialog.setButton("OK", new DialogInterface.OnClickListener() {

Errors:

1st: Multiple markers at this line
– DialogInterface cannot be resolved to a type
– The method setButton(String, new OnClickListener(){}) is undefined for the type

2nd: DialogInterface cannot be resolved to a type

Can anyone tell me what I am doing wrong please?

Thanks!

I’m pretty sure you just aren’t importing the DialogInterface. Try adding this statement to the beginning of your code.

import android.content.DialogInterface;
