私はこの問題について助けが必要です。グリッドレイアウトにアイテムを追加すると、コンテナに追加された重複アイテムやスクロール位置が変化します。ここにXMLとJavaコードがあります。カスタムButtonAdapterを使用してGridlayoutに重複した項目が追加されました。
レイアウト：
<RelativeLayout
android:id="@+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TableRow android:layout_width="wrap_content" android:paddingTop="20dp" android:layout_height="wrap_content" android:id="@+id/tableRow2" android:layout_centerHorizontal="true" android:background="@color/transparent" android:minHeight="110dp">
<ImageView android:layout_height="wrap_content" android:layout_width="wrap_content" android:src="@drawable/school_logo_default" android:layout_gravity="bottom" android:id="@+id/school_logo"></ImageView>
</TableRow>
<ImageView
android:layout_width="fill_parent"
android:layout_height="90dip"
android:layout_alignParentTop="true"
android:src="@drawable/gradient_top"
android:scaleType="fitXY"
/>
<ImageView
android:layout_width="fill_parent"
android:layout_height="90dip"
android:layout_alignParentBottom="true"
android:src="@drawable/gradient_bottom"
android:scaleType="fitXY"
/>
<LinearLayout
android:id="@+id/top"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:gravity="left|top">
<TextView android:layout_height="wrap_content" android:textColor="@color/white" android:layout_weight="1" android:textStyle="bold" android:text="@string/userName" android:layout_width="wrap_content" android:layout_gravity="center_vertical" android:layout_marginRight="20dip" android:gravity="left|top" android:background="@color/transparent" android:paddingLeft="5dp" android:textSize="16px" android:paddingTop="5dp" android:id="@+id/username"></TextView>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingBottom="20dip"
android:layout_alignParentBottom="true"
android:id="@+id/bottom">
<ImageView android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/screen_icon" android:src="@drawable/sl_tools"></ImageView>
</LinearLayout>
<TableRow android:layout_width="wrap_content" android:gravity="center" android:layout_height="wrap_content" android:id="@+id/tableRow1" android:layout_centerInParent="true" android:background="@color/transparent">
<ListView android:columnWidth="120dp" android:id="@+id/gridView1" android:numColumns="4" android:verticalSpacing="10dip" android:gravity="center" android:horizontalSpacing="10dip" android:scrollbars="vertical" android:layout_gravity="center" android:stretchMode="columnWidth" android:background="@color/transparent" android:paddingTop="140dip" android:paddingBottom="80dip"></ListView>
</TableRow>
</RelativeLayout>

私が代わりに実際のアイテムを追加した理由一部重複するアイテムを教えてください。スクロール位置が変更されました。
