Добавление программы LinearLayout программно в Android не работает

Иерархия выглядит следующим образом:

RelativeLayout
- LinearLayout (вертикальный)
  - FrameLayout (вес 5)
    - ImageView
  - Вид (вес 1)

Вид - это просто фиктивный вид для задания расстояния. Я сделал это в макете xml, и он работает. Но когда я хочу сделать это программно, следующие коды не работают.

LinearLayout LL = new LinearLayout(this);
ImageView ladder = new ImageView(this);
FrameLayout ladderFL = new FrameLayout(this);
View dummyView = new View(this);
ladder.setImageResource(R.drawable.ladder1);
LL.setOrientation(LinearLayout.VERTICAL);
LayoutParams LLParams = new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);
LinearLayout.LayoutParams ladderFLParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, 0);
ladderFLParams.weight = 5f;
LinearLayout.LayoutParams dummyParams = new LinearLayout.LayoutParams(0,0);
dummyParams.weight = 1f;

FrameLayout.LayoutParams ladderParams = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT, FrameLayout.LayoutParams.WRAP_CONTENT, Gravity.BOTTOM);
ladder.setLayoutParams(ladderParams);
ladderFL.setLayoutParams(ladderFLParams);
dummyView.setLayoutParams(dummyParams);
LL.setWeightSum(6f);
LL.setLayoutParams(LLParams);

ladderFL.addView(ladder);
LL.addView(ladderFL);
LL.addView(dummyView);
((RelativeLayout) findViewById(R.id.screenRL)).addView(LL);

LinearLayout LL = new LinearLayout(this); LL.setBackgroundColor(Color.CYAN); LL.setOrientation(LinearLayout.VERTICAL); LayoutParams LLParams = new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT); LL.setWeightSum(6f); LL.setLayoutParams(LLParams); ImageView ladder = new ImageView(this); ladder.setImageResource(R.drawable.ic_launcher); FrameLayout.LayoutParams ladderParams = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT, FrameLayout.LayoutParams.WRAP_CONTENT, Gravity.BOTTOM); ladder.setLayoutParams(ladderParams); FrameLayout ladderFL = new FrameLayout(this); LinearLayout.LayoutParams ladderFLParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, 0); ladderFLParams.weight = 5f; ladderFL.setLayoutParams(ladderFLParams); ladderFL.setBackgroundColor(Color.GREEN); View dummyView = new View(this); LinearLayout.LayoutParams dummyParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,0); dummyParams.weight = 1f; dummyView.setLayoutParams(dummyParams); dummyView.setBackgroundColor(Color.RED); ladderFL.addView(ladder); LL.addView(ladderFL); LL.addView(dummyView); RelativeLayout rl=((RelativeLayout) findViewById(R.id.screenRL)); rl.addView(LL);
