自定义viewGroup中放入fragment view,但是fragment中的内容不显示

自定义viewGroup中放入fragment view,但是fragment中的内容显示不到界面上,明明fragment中的oncreateview都走了,而且返回的view不为空?求解!!!

<?xml version="1.0" encoding="utf-8"?>
android:id="@+id/test_viewgroup"
android:layout_width="match_parent"
android:layout_height="match_parent"
>

<TextView
    android:id="@+id/top"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@android:color/black"
    />
<!--<TextView
    android:id="@+id/bottom"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="sssssss"
    android:background="@android:color/white"
    />-->
<FrameLayout
    android:id="@+id/bottom"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
</FrameLayout>

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test_view_group);
//mBottomView = (TextView) findViewById(R.id.bottom);
//mViewGroup = (TestViewGroup) findViewById(R.id.test_viewgroup);
mTopView.setOnClickListener(this);
mBottomFragment = new BottomFragment();
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.bottom, mBottomFragment);
transaction.commit();
}

    public class BottomFragment extends Fragment {
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.test_sliding, container, false);
    return view;
}

}

protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
Log.i("edward", "onMeasure");
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
// 测量子view的大小
//measureChildren(widthMeasureSpec, heightMeasureSpec);
}

@Override
protected void onLayout(boolean changed, int left, int top, int bottom, int right) {
    Log.i("edward", "onLayout");
    int width = getMeasuredWidth();
    int height = getMeasuredHeight();
    for(int i = 0; i < 2; i++) {
        View child = getChildAt(i);
        if (i == 0) {
            child.layout(0, 0, width, height / 2 - mOffset);
        }
        if (i == 1) {
            child.layout(0, height / 2 - mOffset, width, height);
        }
    }
}
