Fragment duplication on Fragment Transaction

Question

Ok, whenever I try to replace a fragment in my application, it only adds the fragment inside of the container the other fragment is, and leaves the current fragment. I've tried calling replace and referencing the view the contains the fragment, and by referencing the fragment itself. Neither of these work. I can add a fragment to a view with the fragment transaction manager, but even if I try to remove it after its been added, it doesn't work. Any help would be appreciated. Here are my files.

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    //Setup the actionabar. Use setDrawableBackground to set a background image for the actionbar.
    final ActionBar actionbar = getActionBar();
    actionbar.setDisplayShowTitleEnabled(false);
    actionbar.setDisplayUseLogoEnabled(true);
    actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
    actionbar.addTab(actionbar.newTab().setText(R.string.home_tab_text).setTabListener(this),true);
    actionbar.addTab(actionbar.newTab().setText(R.string.insert_tab_text).setTabListener(this));

    Fragment fragment = new insert_button_frag();
    FragmentTransaction transaction = getFragmentManager().beginTransaction();
    transaction.replace(R.id.button_fragment, fragment);
    transaction.addToBackStack(null);

    transaction.commit();
}

Here is the layout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <LinearLayout
        android:orientation="vertical"
        android:id="@+id/button_fragment_container"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" >

        <fragment
            android:name="com.bv.silveredittab.home_button_frag"
            android:id="@+id/button_fragment"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />

    </LinearLayout>

    <LinearLayout
        android:orientation="horizontal"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >

        <fragment
            android:name="com.bv.silveredittab.quick_insert_frag"
            android:id="@+id/quick_insert_frag"
            android:layout_width="350dip"
            android:layout_height="fill_parent" />

        <fragment
            android:name="com.bv.silveredittab.editor_frag"
            android:id="@+id/editor_frag"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />

    </LinearLayout>

</LinearLayout>

And here is the fragment code

public class insert_button_frag extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        return inflater.inflate(R.layout.insert_buttons,container, false);
    }
}

Like I have said. I have tried referencing the fragments parent view to replace it, and the fragment itself (by id) and still, it only adds the new fragment, inside the containing view the original fragment is in.

I solved this by using a placeholder in my Layout and then attaching my Fragment to it at runtime.

Like you, if I instantiated my Fragment within my xml layout then the contents would remain visible after replacing it with another Fragment at runtime.
