tabHost的滑动效果监听不到

Question

我的tabHost有三栏，都是listView，想加一个滑动切换tab的效果，结果发现不行，于是
用了个简单的来测试，发现如下问题。

情况一

   android:id="@+id/tab2"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical" >

                <EditText
                    android:id="@+id/editText1"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"

                    android:ems="10" />
            </LinearLayout> 

情况二

 <LinearLayout
                android:id="@+id/tab2"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical" >

                <EditText
                    android:id="@+id/editText1"
                    android:layout_width="fill_parent"
                    android:layout_height="fill_parent"

                    android:ems="10" />
            </LinearLayout>  

这个tab里面只有这个EditText，就android:layout_height不同

然后就发现滑动效果在fill_parent的时候不反应了！

这是什么问题？？？
