create a method that will check all your inputs in your Utils class or can use it in current class

public static boolean checkifEmptyText(String[] fields,Context context) {
    for (String currentField : fields) {
        if (currentField.getText().toString().trim().length() <= 0) {
            return false;
        }
    }
    return true;
}

now check it like this

if(checkifEmptyText(new String[]{all your strings}),context)
{
 Button button = dialog.getButton(AlertDialog.BUTTON_POSITIVE);
button.setEnabled(true);
}
else
{
Button button = dialog.getButton(AlertDialog.BUTTON_POSITIVE);
button.setEnabled(false);
}

You can also do by this:

new AlertDialog.Builder(this)
    .setMessage("This may take a while")
    .setPositiveButton("OK", new android.content.DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
         ((AlertDialog)dialog).getButton(which).setVisibility(View.INVISIBLE);
         // the rest of your stuff
    }
})
    .show();

Use can do like this for positive button:

dialog.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(false);

And, for negative button:

dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setEnabled(false);

You can do this by this way :

    ....your code for alert dialog
    AlertDialog dialog = b.create(); // here b is reference of AlertDialog.Builder and in your case replace b with alertDialogBuilder
    dialog.show();
    Button button = dialog.getButton(AlertDialog.BUTTON_POSITIVE);
    button.setEnabled(false);

Hope this will help.

If i understood your requirement correctly,

You can use a TextWatcher..

How it would work:
Add the textwatcher as a listener for text change to your inputfields, it would ensure a dynamic check on those for being 'filled' and you can associate the visibility of your button or enable/disable it accordingly

Questions which would help:
1. Disable button when edittext fields are empty
2. Use on text changed listener
