想要的效果是这样的，也就是可以上下拖动，顶部蓝色layout固定不动。
代码如下：
//布局如下：
<!-- 顶部蓝色工具栏 -->
<RelativeLayout
android:id="@+id/fujin_top_llayout"
android:layout_width="fill_parent"
android:layout_height="36dp"
android:background="#47a9d0"

android:id="@+id/fujin_top_llayout_lessthan"
android:layout_width="wrap_content"
android:layout_height="30dp"
android:layout_alignParentLeft="true"
android:layout_marginLeft="10dip"
android:paddingLeft="10dp"
android:src="@drawable/fujin_top_llayout_lessthan" />
<TextView

按钮列表是用代码自动生成的GridView，item是TextView。

//此处是初始化一些数据，就不贴了
