Button not aligned in same row

[sayoojvalsan]

CustomDialog.Builder builder = new CustomDialog.Builder(context, "Discard Item ?", "Discard");

    builder.darkTheme(false);
    builder.positiveColor(context.getResources().getColor(R.color.theme_default_primary));
    builder.negativeColor(context.getResources().getColor(R.color.theme_default_primary));
    builder.negativeText("Cancel");
    CustomDialog customDialog = builder.build();

    customDialog.show();
    return customDialog;

While using the above code, I get two button stacked up instead showing in one row.

How do I get one button on left and other on right ?
