Question

I created a generic OkCancelDialog class that is conveniently invoked throughout my app via a static method:

  static public void Prompt(String title, String message) {
    OkCancelDialog okcancelDialog = new OkCancelDialog();
    okcancelDialog.showAlert(title, message);     
  }

For various reasons I need the onClick listener in the activity, so in the activity I have:

  public void onClick(DialogInterface v, int buttonId) {
    if (buttonId == DialogInterface.BUTTON_POSITIVE) { // OK button
         // do the OK thing
    }
    else if (buttonId == DialogInterface.BUTTON_NEGATIVE) { // CANCEL button
         // do the Cancel thing
    }
    else {
      // should never happen
    }
  }

This works great with a single dialog in the app, but now I want to add another OK/Cancel dialog, handled by the same activity. As far as I can tell, only one onClick() can be defined for the activity, so I am not sure how to go about implementing this.

Any suggestions or tips?

Try something like this…

public class MyActivity extends Activity
    implements DialogInterface.OnClickListener {

    // Declare dialogs as Activity members
    AlertDialog dialogX = null;
    AlertDialog dialogY = null;

    ...

    @Override
    public void onClick(DialogInterface dialog, int which) {

        if (dialogX != null) {
            if (dialogX.equals(dialog)) {
                // Process result for dialogX
            }
        }

        if (dialogY != null) {
            if (dialogY.equals(dialog)) {
                // Process result for dialogY
            }
        }
    }
}

EDIT This is how I create my AlertDialogs…

private void createGuideViewChooserDialog() {
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Select Guide View")
        .setSingleChoiceItems(guideViewChooserDialogItems, currentGuideView, this)
        .setPositiveButton("OK", this)
        .setNegativeButton("Cancel", this);
    guideViewChooserDialog = builder.create();
    guideViewChooserDialog.show();
}
