Не изменяется высота FrameLayout при замене фрагментов

Question

Как, после вставки маленького фрагмента, после большого, FrameLayout возвращался до размеров маленького? Я пытался это делать через:

            ((FrameLayout) findViewById(R.id.frameLayout1_wordsAdd)).getLayoutParams().height = LayoutParams.WRAP_CONTENT;
            ((LinearLayout) findViewById(R.id.linearLayout1_wordsAdd)).getLayoutParams().height = LayoutParams.WRAP_CONTENT;

Но безуспешно.

Чтобы было понятнее, вот, что выходит:

Вот .xml разметка:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="45dp"
    android:layout_margin="3dp"
    android:background="@color/white"
    android:orientation="horizontal" >

    <Spinner
        android:id="@+id/spinner_forms"
        android:layout_width="match_parent"
        android:layout_height="45dp" />
</LinearLayout>

<FrameLayout
    android:id="@+id/frameLayout1_wordsAdd"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="3dp"
    android:layout_marginRight="3dp" >
</FrameLayout>

<Button
    android:id="@+id/btnOK_wordsadd"
    android:layout_width="300dp"
    android:layout_height="40dp"
    android:layout_margin="3dp"
    android:background="@drawable/button1"
    android:text="Готово" />

Для ЮрийСПб:

При попытке сделать FrameLayout.LayoutParams params = (FrameLayout.LayoutParams) fr.getLayoutParams(); вылетает. Вот сообщения из logcat`a:

Код, который вышел, после добавления удаления фрагментов:

    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        public void onItemSelected(AdapterView<?> parent, View itemSelected, int selectedItemPosition, long selectedId) {
            switch (form) {

Answer 1

Тут

((FrameLayout) findViewById(R.id.frameLayout1_wordsAdd)).getLayoutParams().height = LayoutParams.WRAP_CONTENT;

вы назначаете значение полю объекта, но потом этот объект не присваиваете FrameLayout. Засим надо ещё и LayoutParams присвоить вьюхе:

 FrameLayout fr=(FrameLayout) findViewById(R.id.frameLayout1_wordsAdd);
 FrameLayout.LayoutParams params=(FrameLayout.LayoutParams)fr.getLayoutParams();
 params.height = LayoutParams.WRAP_CONTENT;
 fr.setLayoutParams(params);

UPD_0:

При этом класс перед LayoutParams должен быть родительским для того вью, чьи LayoutParams мы получаем. Т.е., если наш FrameLayout лежит в LinearLayout, то класс LayoutParams будет выглядеть LinearLayout.LayoutParams

Так же при замене одного фрагмента другим надо сначала удалить фрагмент методом remove, а потом добавить методом add. При использовании replace, судя по всему, фрагменты из разметки не удаляются, а как бы становятся невидимыми, из-за чего контейнер принимает размеры самого большого лежащего в нём фрагмента.

Т.е. примерно так:

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
    {
        public void onItemSelected(AdapterView<?> parent, View itemSelected, int selectedItemPosition, long selectedId)
        {
            FragmentTransaction fTransaction;
            //находим добавленный фрагмент и его удаляем
            //а не пытаемся удалить несуществующий фрагмент
            Fragment fragmentToRemove = getFragmentManager().findFragmentByTag("myFragmentTag");
            if (fragmentToRemove != null)
            {
                fTransaction = getFragmentManager().beginTransaction();
                fTransaction.remove(fragmentToRemove);
                fTransaction.commit();
            }

            //возможно это даже и не нужно, если мы удаляем фрагмент
            FrameLayout fr = (FrameLayout) findViewById(R.id.frameLayout1_wordsAdd);
            LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) fr.getLayoutParams();
            params.height = LinearLayout.LayoutParams.WRAP_CONTENT;
            fr.setLayoutParams(params);

            switch (selectedItemPosition)
            {
                case 0:
                    fTransaction = getFragmentManager().beginTransaction();
                    //добавляем фрагмент с тегом по коему будем искать
                    fTransaction.add(R.id.frameLayout1_wordsAdd, new WordsAddForm1_Fragment(), "myFragmentTag");
                    fTransaction.commit();
                    break;
                case 1:
                    fTransaction = getFragmentManager().beginTransaction();
                    //добавляем фрагмент с тегом по коему будем искать
                    fTransaction.add(R.id.frameLayout1_wordsAdd, new WordsAddForm2_Fragment(), "myFragmentTag");
                    fTransaction.commit();
                    break;
            }
        }
    });
}
