相对布局中的ScrollView无法正常工作，影响布局

Question

我想要在我的活动布局中滚动视图。我试过很多方面，但没有成功。最后两个按钮重叠。我想在活动布局中添加更多按钮。请给我一些建议摆脱这个问题。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/cream"
    android:scrollbars="vertical">

  <Button
    android:id="@+id/button7"
    android:layout_width="70dp"
    android:layout_height="50dp"
    android:layout_alignBottom="@+id/Bconfiguration"
    android:layout_toLeftOf="@+id/Bconfiguration"
    android:layout_toStartOf="@+id/Bconfiguration"
    android:background="@drawable/round_button"
    android:gravity="center_vertical|center_horizontal"
    android:textColor="#fff" />

  <Button
    android:id="@+id/button8"
    android:layout_width="70dp"
    android:layout_height="50dp"
    android:layout_alignTop="@+id/Bquestions"
    android:layout_toLeftOf="@+id/Bquestions"
    android:layout_toStartOf="@+id/Bquestions"
    android:background="@drawable/round_button"
    android:gravity="center_vertical|center_horizontal"
    android:textColor="#fff" />

  <Button
    android:id="@+id/button9"
    android:layout_width="70dp"
    android:layout_height="50dp"
    android:layout_alignTop="@+id/Bscenario"
    android:layout_toLeftOf="@+id/Bscenario"
    android:layout_toStartOf="@+id/Bscenario"
    android:background="@drawable/round_button"
    android:gravity="center_vertical|center_horizontal"
    android:textColor="#fff" />

  <Button
    android:id="@+id/button10"
    android:layout_width="70dp"
    android:layout_height="50dp"
    android:layout_alignBottom="@+id/button3"
    android:layout_toLeftOf="@+id/button3"
    android:layout_toStartOf="@+id/button3"
    android:background="@drawable/round_button"
    android:gravity="center_vertical|center_horizontal"
    android:textColor="#fff" />

你添加了scrollview的第一件事，我瘦了你可能尝试在relativelayout里面添加scrollview并试图在不可能的地方添加多个按钮，因为scrollview只包含单个直接子代码尝试下面的代码，你会得到一个想法

<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true">
<RelativeLayout 
    android:id="@+id/main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/cream"
    android:scrollbars="vertical">

    <Button
        android:id="@+id/button7"
        android:layout_width="70dp"
        android:layout_height="50dp"
        android:layout_alignBottom="@+id/Bconfiguration"
        android:layout_toLeftOf="@+id/Bconfiguration"
        android:layout_toStartOf="@+id/Bconfiguration"
        android:background="@drawable/round_button"
        android:gravity="center_vertical|center_horizontal"
        android:textColor="#fff" />

    <Button
        android:id="@+id/button8"
        android:layout_width="70dp"
        android:layout_height="50dp"
        android:layout_alignTop="@+id/Bquestions"
        android:layout_toLeftOf="@+id/Bquestions"
        android:layout_toStartOf="@+id/Bquestions"
        android:background="@drawable/round_button"
        android:gravity="center_vertical|center_horizontal"
        android:textColor="#fff" />

    <Button
        android:id="@+id/button9"
        android:layout_width="70dp"
        android:layout_height="50dp"
        android:layout_alignTop="@+id/Bscenario"
        android:layout_toLeftOf="@+id/Bscenario"
        android:layout_toStartOf="@+id/Bscenario"
        android:background="@drawable/round_button"
        android:gravity="center_vertical|center_horizontal"
        android:textColor="#fff" />

    <Button
        android:id="@+id/button10"
        android:layout_width="70dp"
        android:layout_height="50dp"
        android:layout_alignBottom="@+id/button3"
        android:layout_toLeftOf="@+id/button3"
        android:layout_toStartOf="@+id/button3"
        android:background="@drawable/round_button"
        android:gravity="center_vertical|center_horizontal"
        android:textColor="#fff" />



</RelativeLayout>
</ScrollView>
