Попытка установить верхний край линейной компоновки программно

У меня есть LinearLayout внутри прокрутки. Я хочу, чтобы установить верхний предел LinearLayout к 50dp с использованием программно ниже кодаПопытка установить верхний край линейной компоновки программно

convertView = inflater.inflate(R.layout.apps_detail_item, parent, false); 
    LinearLayout childLayout = (LinearLayout) convertView.findViewById(R.id.childLayout); 
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
      LinearLayout.LayoutParams.WRAP_CONTENT, 
      LinearLayout.LayoutParams.WRAP_CONTENT 
    ); 
    params.setMargins(0, 50, 0, 0); 
    childLayout.setLayoutParams(params);

Но когда я пытаюсь запустить этот код, мое приложение становится все аварии. Вот журналы ошибок:

R.id.childLayout - какой вид? в шаблоне xml у вас есть –

@Dmitri Gudkov Его линейная компоновка. Я также добавил соответствующий XML-файл. –

Я решил это сам. Вот код

FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); 
      params.setMargins(0, 50, 0, 0); 
      childLayout.setLayoutParams(params);
