Answer 1

Please try the following:

public static View getLayoutByRes(@LayoutRes int layoutRes,@Nullable ViewGroup viewGroup)
{
    final LayoutInflater factory = getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    return factory.inflate(layoutRes, viewGroup);
}

TextView tv = (TextView) getLayoutByRes(R.layout.xxx ,Null).findViewById(R.id.editd);
