我在 xml 文件活动中创建了三个按钮，当我单击某个按钮时，将显示滚动，这导致隐藏屏幕底部的其他按钮，我该如何解决：

xml结构：

<LinearLayout>

<!-- Section 1 -->
    <Button/>

    <ScrollView>

        <TableLayout>
    <!-- Components -->
        </TableLayout>
    </ScrollView>

<!-- Section 2 -->
<Button/>

    <ScrollView>

        <TableLayout>
    <!-- Components -->
        </TableLayout>
    </ScrollView>

<!-- Section 3 -->
    <Button/>

    <ScrollView>

        <TableLayout>
    <!-- Components -->
        </TableLayout>
    </ScrollView>

</LinearLayout>

为每个滚动视图尝试这个

<ScrollView
        android:id="@+id/Section_1"
        android:layout_width="fill_parent"
       android:layout_height="0dp"
        android:layout_weight="1"
        android:visibility="gone" >
