How Do You Disable A Button Inside Of An Alertdialog?

I am trying to write an AlertDialog with 3 buttons. I want the middle, Neutral Button to be disabled if a certain condition is not met. Code int playerint = settings.getPlayerInt()

Solution 1:

You can't call getButton() on the AlertDialog.Builder. It has to be called on the resulting AlertDialog after creation. In other words

AlertDialog.Builderalertbox=newAlertDialog.Builder(this);
//...All your code to set up the buttons initiallyAlertDialogdialog= alertbox.create();
Buttonbutton= dialog.getButton(AlertDialog.BUTTON_NEUTRAL);
if(monsterint > playerint) {
    button.setEnabled(false);
}

The builder is just a class to make constructing the dialog easier...it isn't the actual dialog itself.

Better solution in my opinion:

AlertDialog.Builderbuilder=newAlertDialog.Builder(context); 
builder.setPositiveButton("Positive", newDialogInterface.OnClickListener() {
    publicvoidonClick(DialogInterface dialog, int whichButton) {
        // some code
    }
});
AlertDialogalertDialog= builder.create();
alertDialog.setOnShowListener(newDialogInterface.OnShowListener() {
            @OverridepublicvoidonShow(DialogInterface dialog) {
                if(**some condition**)
                {
                    Buttonbutton= alertDialog.getButton(AlertDialog.BUTTON_POSITIVE);
                    if (button != null) {
                        button.setEnabled(false);
                    }
                }
            }
        });

Solution 3:

The trick is that you need to use the AlertDialog object retuned by AlertDialog.Builder.show() method. No need to call AlertDialog.Builder.create().

Example:

AlertDialogdialog= alertbox.show();
        if(monsterint > playerint) {
            Buttonbutton= dialog.getButton(AlertDialog.BUTTON_NEUTRAL);
            button.setEnabled(false);
        }
