grid.xml中,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<GridView
         android:id="@+id/gridview"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"
         android:numColumns="4"
         />
</LinearLayout>
目前的效果是此GridView显示在界面中间,现需:让此GridView在界面底部,如何实现呀,thanks
