For my android application I made a class that contains an alertdialog with just a yes and a no button.

I use winforms a lot and I was thinking the alertdialog in android was the same. Well it isn’t.

```java public class YesNoAlertDialogImpl implements YesNoAlertDialog {

@Override
public boolean show(View view, String title, String message)
{
    boolean result = false;
    AlertDialog.Builder alert = new AlertDialog.Builder(view.getContext());

    alert.setTitle(title);
    alert.setMessage(message);

    alert.setPositiveButton("Yes",new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialogInterface, int i) {
            result = true;
        }
    });

    alert.setNegativeButton("No", null);
    alert.show();
    return result;
}

}``` Which I would then use as such.

java if(!yesNoAlertDialog.show(view, "title", "message") return; //do your thing here But the above does not work because unlike the messagebox, the alertdialog does not run on the UIthread and your code will not wait for the alertdialog to return for you.

But it is this I needed to do.

```java public class YesNoAlertDialogImpl {

@Override
public void show(View view, String title, String message, DialogInterface.OnClickListener positiveClickListener, DialogInterface.OnClickListener negativeClickListener)
{
    AlertDialog.Builder alert = new AlertDialog.Builder(view.getContext());

    alert.setTitle(title);
    alert.setMessage(message);

    alert.setPositiveButton("Yes",positiveClickListener);

    alert.setNegativeButton("No", negativeClickListener);
    alert.show();
}

}``` With this as the implementation.

java yesNoAlertDialog.show(view, "title", "message" ,new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialogInterface, int i) { //do your thing here } },null); If one doesn’t make mistakes, one doesn’t learn.
